Radiator Fan Woes. RTFM



Thanks for everyone’s input on my radiator fan woes. Jody saved the day and sent me his stocker. I got it in the mail on Friday. I got off work at 8pm that night and got started in the garage at around 10:30pm. I hooked up both fans and listened to each within minutes of each other and it was clear that mine had a high pitched whine to it that Jody’s fan lacked. Hard to pick up on in the video, but easier to hear in person.

The wrenching part of it was pretty much just changing out parts. As Joe likes to say, this part could have been done with the ZRX tool kit on the side of the road. The tricky part was the coolant. I called John and Chuck ahead of time and asked them about the specifics of refilling the bike with coolant after having the radiator off. I wanted it to be simple. I didn’t want to have to mess with bleeder valves and pressure testers.

So we’re off to the races. I started off by adding the coolant mixture. When it filled up to the filler neck, I started the bike and ran it and waited for the level to go down. Instead of going down, it gradually rose and then went down……..down onto the floor of my garage. I repeated this process about three times and knew I wasn’t doing something right. So into the house I went and re-read the repair manual about how to use the bleeder bolts and valves. Back out to the garage…now confident with Kawasaki knowledge. I started the bike and cracked the bleeder bolt on the water pump. A very audible hissing ensues and within seconds coolant mixture emerges. Tighten the bolt and done. I did the same with the bleeder valve on the thermostat housing. By this point, the water level had gone way down and I was able to add at least one more cup of coolant….maybe two. Also very noticeable now was that the water was swirling in the filler neck and not just sitting still with the occasional bubble. Clearly the water was now actually circulating. How cool….pardon the pun. Buttoning it up was text book.

Lesson? RTFM. Read the Fuggin’ Manual.

Man Day at the Dynos - ZRX Edition

I won't bother repeating the Dyno Day setup as it is all in the previous Fizzy dyno post. Needless to say, I had no preconceived notions as to what I expected out of the Fizzy for horsepower and the 150hp pull was a nice surprise. As for the ZRX, well that is a whole different story. You guys have listened to me complain about my ZRX over the last year and given that I pulled the numbers I did on the ZRX, I feel the majority of my issues probably revolved around the coil wire that was working during the same time frame. Although I had fixed the coil wire issue on the ZRX and confirmed it ran, I only took it around the block and never ran it hard before getting the Fizzy and putting the ZRX into hibernation. I can't help but think my ZRX was not running as it should have been for months prior to me finding/fixing the coil wire issue and that reinforced some of the negative feelings I had for the bike based on the pitted Muzzy cams and my "imaginary" pinging issues. In any case, you can see from my post documenting my return to the ZRX World, the bike is running stronger than ever and I am extremely pleased with it!

Back on topic, the first pull on the ZRX showed 142hp with an A/F above 15. Bike was so lean it was shooting flames out the exhaust which you can see in the video and really popping on decel. Driveability on the street was good but I was definitely running too lean. As dyno runs were only $20, Dick and Brett suggested we rejet the bike to see what kind of difference we could make going from 135 to 138 mains. Brett ran me to the house in his truck, we picked up all the tools needed and rejetted in the parking lot. I paid for another run and the dyno operator was confused as to why I wanted to run it again. I explained we had rejetted the bike and wanted to see where A/F was at. He seemed duly impressed! Second pull netted a solid 147hp with A/F still being well above 14. At Dick's suggestion, I will come out on the air screw 1/4 turn next time I have the carbs off but I think going up any more on the mains will kill my driveability and mileage. Also, a little lean in Tulsa would only fatten up as I gained altitude in Arkansas so all in all, I think I'd prefer to be a little on the lean side. I'd love to hear anyone's thoughts on the subject.

Maybe it was just my imagination but the bike seemed peppier on the way home and I am looking forward to getting it out where I can really "wick it up"! Looking at the power curve of the second dyno run, I think it explains pretty clearly why we all love the ZRX so much. Overlay that power curve over the Fizzy power curve and there isn't even a question as to which bike would be more "fun" to ride. All in all we had a great time and I feel I got my money's worth for the $60 I spent. It was nice to spend the day with my friends and a bunch of motorcycle guys standing around watching dyno runs like they were a burlesque show. There were some pretty sick bikes out there with one guy trailering his drag bikes from Fayetteville to take advantage of the dyno. Enjoy the videos and pics!

Man Day at the Dynos - FZ1 Edition

A local bike shop, Metric Cycles, had an "End of Summer" bash on Saturday at which they were offering $20 dyno pulls. I thought this would be a great opportunity to get the Fizzy baselined for horsepower and also, I hadn't had the ZRX officially dynoed since I added the hi-comp pistons and cams so was excited/nervous to get that done. I invited a few folks to join me and Dick, Brett and I headed up to the shop arriving right at 10:00am, Dick on the Fizzy, me on the ZRX and Brett in his truck. Dyno runs were from 11:00am to 2:00pm and I was just sure bikes would be lined up in the streets for the bargain dyno runs and I wanted to get in line so we would be sure to get a pull. Well, I guess the rest of Tulsa wasn't quite as excited as I was and Dick, Brett and I were the first 3 people to show up. Fortunately there were donuts and coffee available and we sat around for a while catching up and talking motorcycles. After "breakfast", I got both bikes signed in and paid for and we rode around back to the dyno which was loaded with a beater V-Max that was just finishing a wicked 90hp pull. As much as I lusted over the V-Max in the late-80s, they seem to disappoint every time I see one on a dyno!

As we were the only bikes there, the Fizzy immediately went on the dyno. Now I really had no idea what to expect as I had read so many different things on the Fizzy board concerning various mods and expected horsepower. All I have done to the Fizzy performance wise to this point has been to add an Akra slip-on I got from Scott Vint for $300 shipped, install Ivan's Fuel Cut-Off Eliminator for about $100, gutted the catalytic converter in the mid-pipe along with opening up the airbox. Collective wisdom on the FZOA says these mods require a power commander lest "extreme damage" be inflicted on the engine due to an exceptionally lean A/F ratio. "Danger, Danger!". Well, although I had intended to pick up a Power Commander at some point just to get to play with custom mapping, I almost pulled the trigger as soon as I found out about the dyno day thinking I would need it to make maximum horsepower. As you can see from the dyno chart below, that would have been an exceptional waste of money and I may still buy one but it is by no means "required".

The other guy in the video, assisting the dyno operator, is Brad and is someone I have dealt with before as he mounted my last set of Diablos for me. Interestingly enough, it turns out he has an '07 Fizzy as well but his is bone stock but more on that below. Once the Fizzy is secured on the dyno, the operator brings the bike up to speed and pulls some baseline readings. After his first full pull, I notice him glance over at Brad giving him a strange look. Although I can see the dyno monitor, I can' really tell what is going on but fear the A/F might be so out of whack that the operator is concerned to pull again. That turns out not to be the case as the operator executes another couple of pulls. As the operator finishes the run, Brad steps up to the operator who says something that I can't quite hear and to which Brad responds with a blank look. At this point, all I am thinking is that either my A/F is way out of whack or my bike has just pulled some really pathetic numbers and they are trying to decide how to break it to me. Neither is the case and the brief exchange between the operator and Brad is due to the Fizzy just pulling 150hp! The look on Brad's face was actually surprise as he had just dynoed his bike at 133hp! Cool! See video below and then dyno chart below that.

I'm Back!!

As I e-mailed Douglas Wednesday morning last week before heading into the office, I had gotten my ZRX fired up Tuesday night with it taking a little more effort than I thought it would. I don’t know why I thought she would fire right up as the fuel tank was almost empty when I parked her 4 months ago and with all the coil issues and misfiring I was going through just prior to putting her on the rear stand, I think a couple of the plugs had been wet-fouled and were marginal at best. In any case, after draining the battery trying to get her started, I put her on the charger and finally got her cranked up. After a few minutes of idling, she smoothed right out and although I wanted to take her out for a spin, it was late so I just put her on the trickle charger and closed the door to the garage with the sweet sound of the Kerker still ringing in my ears.

Waking up Wednesday morning, I had not intended to ride the ZRX to work as she was pretty dusty and I wanted to get her cleaned up, along with an oil and filter change, before taking her out on the streets but as I walked out into the garage to saddle up the Fizzy, she just seemed to beckon to me. Having a total lack of self-control, I asked myself “why not?”, dropped her off the rear stand, rolled her out onto the driveway and at the first push of the starter, she cranked right up. After gearing up and getting on the bike, I could immediately feel the difference in weight between the ZRX and the Fizzy as I rolled the bike around in the driveway. The ZRX is definitely more of a handful to maneuver around at rest but I managed to get her out into the street with no issues, got her pointed in the right direction, snicked her into first gear and off we went.

I have been off of the ZRX and riding the Fizzy for enough time that I had forgotten all the subtleties of my ZRX. First thing I notice is that my clutch setup with HD springs all the way around is a little absurd to pull. That combined with my shorty Pazzo clutch lever and it feels like I am setting a grizzly trap every time I grab for some clutch! Although I had been commenting on the smooth shifting on the Fizzy, the Armz’s shifter rod I have on the ZRX provides very accurate feel and minimal gearshift slop, much more precise than the Fizzy shifter. I now feel the shifting issues I have complained about on my ZRX are due to improper lever adjustment which I will address by dropping the lever a spline or two on the shaft. Also, I had the clutch set up on the ZRX to begin engaging almost instantly upon release whereas the Fizzy releases much later in the throw. A quick flip of the adjusters on the Pazzos and a nice compromise was found to bring the two clutch releases to a similar point. Another difference immediately noticed was the seating position between the ZRX and the Fizzy. Although subtle, when sitting astride the Fizzy, one feels encapsulated within the bike due to the lower seating position along with the wrap around fairing and gauge package. Sitting astride the ZRX is more like sitting on my dirt bike, you are sitting “on” the bike, not “in” the bike. Other than that, the ergonomics are comparable and I find both bikes equally comfortable.

Off and running and the first thing I notice is the sound! This thing sounds like a motorcycle should sound and the Kerker is everything the Akra on the Fizzy is not. It is crude, unrefined and screams "look this way NOW"! The second thing I notice is how it keeps wanting to fall over in every neighborhood corner I go around. Yikes! I had forgotten how much attention this bike requires at slow speed! Where the Fizzy has very light steering and almost seems on remote control at times, the ZRX has to be steered through the neighborhoods and needs constant attention. The third thing I notice is how bad the suspension on my Fizzy is in comparison to my ZRX suspension. The ZRX handling is taught but still soaks of the small road variations with ease whereas the Fizzy is like, to quote Douglas, “riding a go-kart”. It is that stiff and any decision of mine to keep the Fizzy would need to include addressing the suspension issues. In all fairness, I have not spent the time adjusting the Fizzy suspension to suit my weight but I am fairly certain it would never get to the level of the ZRX suspension.

Out of the neighborhood, I chortle my way along surface streets and take the long way to get to an entrance ramp I know I can hammer it on. I let the ramp clear, get the bike straightened up and hammer the throttle in first gear as I typically do on the same ramp on the Fizzy. It didn’t take me long to remember how bad an idea this is on the ZRX as the bike proceeded to launch itself straight up in the air. WOW!! The Fizzy is geared so much taller in first whereas it seems the ZRX is geared to pull stumps out of the ground. The rest of the ride to work was uneventful with the most significant difference on the freeway being the absolute butter smoothness of the Keihin CVK carbs, especially at very small throttle adjustments.

Trust me, I am aware of all the mystique the ZRX brings to the table when talking about torque but it is incredible how different the power delivery is on the ZRX versus the Fizzy. I realize I am overstating the obvious and preaching to the crowd but it was still stunning and I was grinning ear-to-ear all day at work! I had gotten a little taste of the ZRX torque riding Dick’s bike back from Mountain View but it was nice to be back in the saddle of my own ZRX again! When purchasing the Fizzy, I knew I needed to give myself enough time on the Fizzy to let the “new” wear off before I ever thought about making a decision that would separate me from my ZRX. I know now that I could never get rid of her, end of story, as the ZRX has too much character and too much of my blood, sweat and tears in her. This bike has a special place in my heart and will be with me until the end!

Pocket Biking "Under the Lights"

Hey all. I deleted the "Fan Noise" thread because it had served its purpose and I didn't need it taking up space.

I wanted to post this Youtube video up though. We raced "exhibition style" last Thursday night in a new location here in KC. It was at a local sports bar that has a bike night. It was cool as shit racing at night, something I had never done. We we're trying to drum up a little more support for the sport.

Also wanted to show off my new camera, which shoots video in HD. Enjoy. In order to get the full effect and resolution, make sure you click the "HQ" button in the bottom right of the view window.

My First Love

Here's a pic of the first car I ever owned. It's a 1974 Toyota Celica and obviously not the actual car I owned but an excellent example highlighting the beautiful lines of the car. I have been playing around with the idea of getting one to restore but fortunately I am too lazy for such an endeavor!

Finally!!

Well, I have had my iPhone for almost a week now and am completely disappointed in myself for having put off purchasing one for this long. You guys know I am a techie, love my computers and all of the latest A/V toys but I am not an early adopter of anything. I could bore you with a bunch of reasons why I have put it off for so long but the bottom line is I hate following the crowd and so many people were on the iPhone bandwagon.

Well let me tell you this, there is a reason there are so many people on the apple-cart as they have this smart phone thing figured out and the iPhone is as simple and easy a device to use as I have ever put my hands on. The user interface is intuitive and straight-forward with key user settings only 1 or 2 levels deep, not 6 levels deep like on my Samsung Blackjack! The “touch” interface is exquisite making navigation through the phone just plain fun!

After hammering on this thing for an entire week now, the only two things I see as issues are battery life and the digital keyboard. If hooked up to Wi-Fi, downloading/installing apps, watching YouTube videos and doing a lot of Facebook updates and e-mailing, the battery won’t get you through the day. If used as most regular adults use phones, I imagine 2 days before charging would be possible. As for the keyboard, to keep the form factor slim, Apple chose to go with a digital keyboard on the screen and this will take me some additional time to get used to.

As you have probably heard, the “Apps” are what this phone is all about and this unit has the power to deliver them running at 600 mhz with 256MB of dedicated RAM. For Christ’s sake, I have a running desktop with stats less than that! This power, coupled with an accelerometer and built-in GPS gives you a device that can do essentially anything. There are apps for everything from online banking to blogging to letting you know what’s going on in town to auto performance apps that give you ¼ mile times and horsepower as well as reading/clearing error codes. Anything you can think of and I mean anything!

For those of you wanting to get in on the cheap, the 2nd gen iPhone 3G is still available for $99 if you are eligible for an upgrade and sign a 2-year contract with AT&T. The final point of contention for me in getting the iPhone was that you have no choice but to opt for the $30/month Apple data package in addition to your standard calling plan. For me it wasn’t as big a deal as I already had a $15/month data package for my Samsung, but it was just the idea that AT&T and Apple had me over a barrel on this with no options. Given what I know now, I would do it in a heartbeat even at $30/month as the device is that frakin' convenient. I have just begun to scratch the surface of what this device can do and will keep everyone posted.
