  1. I assume you are buying Pilot Powers because you like to go fast around corners.

    (If not, I'd be shopping for a tire that lasts longer than a Pilot Power)

    A 190 is too wide for the stock rim. It was designed for a 6 inch rim. Mounting that tire on a 5.5 inch rim will change the profile.

    Typically it will make your bike handle worse. How much worse depends on how hard you corner.

  2. I'd like to know why it is that the various dyno companys don't conform to a unified standard. Hence 1hp = 746 watts of power etc.

    The dynojet dyno was developed as an inexpensive alternative to other dynamometers. It works by measuring the time it takes to accelerate a heavy drum. A mathmatical algorythm is used to estimate actual torque/hp. This algorythm was developed after much testing in order to give results close to what you would get from dynos that apply resistance.

    Regular dynamometers apply resistance to the spinning drum (either electrically in the case of the eddy current, or by using hydraulic pressure) These dynamometers measure the actual torque generated, and from there they can display horsepower by using the standard calculation.

    So, which one would you trust to give the most accurate results?

    If I wanted something to brag about, I would go with whatever system gives the biggest numbers. :icon_evilgrin:

    If I wanted to tune my bike for all operating conditions, I would use the eddy current dyno, and use the hp/torque numbers only as reference points.

    If you did nothing but drag race, a dynojet dyno may actually work best. Anything that you do to help accelerate the drum faster (such as a lightened crankshaft or lighter flywheel) may not show as increased horsepower on a regular dyno, but can help you at the drag strip.

  3. I had Lindemann redo my forks, including springs. He spends a lot of time reducing stiction on the BlackBird forks.

    I was extremely happy. After I put them back on, I found that even the preload was dead on.

    The ride was firm, but the forks soaked up bumps like the stock forks never did.

    Lindeman supplied and set up a Penske rear shock at the same time. I would use him again.

  4. I never checked mine until around 40,000 miles because everyone said that they never go out of adjustment. I had a number of valves that checked out of spec. They were on the loose side.

    I would have expected them to be tight. So, they may have been loose all along.

  5. Based on a 20 mile ride with a borrowed GPS (at a bunch of different speeds), and what has been posted online, I assumed an 8% speedometer error. I found it was not all that easy on a short ride with a GPS stuck by velcro to my tank bag to verify the speedometer to the GPS. After the ride, my odometer showed a 3% error, which was confirmed by boring rides on the interstate where I could check my mileage against mile markers.

    I decided to set my speedohealer at 6% as a compromise between the speedometer and the odometer. To my surprise, the 6% adjustment brought my speedometer almost dead on. This has been confirmed by a number of those side-of-the road radar trailers, and at least one LEO. :icon_frown:

    My odometer is now 3% slow instead of 3% fast. My perceived fuel mileage has dropped by about 6% :icon_think: Duh.

  6. It's definately not the clutch. The clutch makes a different noise.

    It's the cam chain.

    It acts like it takes a little while for the oil pressure to build in the CCT before it tensions properly.

    I might try an oil additive like BG EPC to see if this makes a difference.

  7. I was just wondering if anyone else gets noise from their cam chain when their engine is first started?

    It happens at a lower rpm than what is usually reported. (from about 2000-3500 rpm)

    It's the typical "bag-o-marbles" rattle.

    The noise goes away after a few minutes of riding.

    I replaced the original CCT with one of the X11 models maybe 20,000 or so miles ago.

  8. I dropped the inner fender down, and installed my remote reservoir on the inside of left side of the subframe. This makes it easy to get to the adjuster. You just pop the seat and it's right there.

    It also hides the installation from prying eyes.

  9. Now we are back to the origional thread, and Tom has asked the question I have.

    How is the ride at the higher speeds. I have only seen 172 indicated (155?). I know things are busy even at those modest speeds.

    Salt flat bikes seem to lose traction as they go faster. This makes going faster, and straight a problem.

    How about my beloved Bird. Does it continue to hunker down, and get smoother?

    260 MPH on a street bike! On Sunday, October 30, Lee Shierts smashed out a 260.2886 MPH pass at the East Coast Timing Association's (ECTA) Maxton, NC one-mile track to become the first street bike rider in history to set an official record over 260 MPH. Shierts rode the Rich Yancy built and tuned "BUD BUSA" Suzuki Hayabusa through the 132-foot traps in only 0.34577 seconds, after a one-mile

    acceleration from a standing start. Shierts' record is the new world, American, association, and track record for street bikes. The red, highly modified 1999 Suzuki Hayabusa is equipped with a "Mr Turbo" turbo system; that is basically a standard system with an ice intercooler fabricated by Yancy. Yancy reports about 500 horsepower in the tune up used for the 260 MPH record run. Although Yancy's bike has nearly standard wheelbase and fairings, his chassis may carry up to 200 pounds of ballast, in an effort to find and control traction. In repeated testing, Yancy and team riders Shierts, Wayne Pollack, and Scott Guthrie found that too much rear-wheel traction was possible, allowing the front wheel to lift at over 240 MPH. This raised the possibility of a "power wheelie" going over backwards at near 250 MPH, especially if the air got under the bike and continued the lifting the bike even after the throttle was closed. Too little rear wheel traction, the bike would spin the tire for 5,280 feet, and reduce top speed. Yancy and Shierts used Saturday's ECTA racing as a tuning and practice session in preparation for the expected better weather on Sunday morning. With 5-8 MPH headwinds, and with temperatures as high as the 70's, Shierts rode passes of 245.9084 MPH, 252.3412 MPH and 256.2424 MPH, all national speed records. Giving in to the high winds and high temperatures, the team packed up for the day at only 3:30 pm. Sunday dawned beautifully cool and clear. First ECTA record runs began at 8:00 am, but Yancy and Shierts waited until almost 9:00 am to bring the Bud Busa to the line. Yancy risked the chance of bad winds, hoping to see that the crumbling World War Two concrete track was clean, and the timing equipment was "working good". Off the trailer, with no warm-up or practice, Shierts made an almost flawless run at 260.2886 MPH to take the record in a 1-3 MPH headwind and about 54-55 degree temperature. Combining Shierts' last run of Saturday, and his first run of Sunday, Bonneville style, Shierts established a two-run average of 258.2655 MPH. The fastest street bike record at Bonneville is 252.832 MPH. With Shierts aboard, the Bud Busa was the first to set a street bike record over 250 MPH, in October of 2004. He was also the first to break 255 MPH, in October 2004. The Bud Busa, with veteran team rider Scott Guthrie aboard, holds the 251.148 MPH motorcycle track record at the Goliad, Texas "Texas Mile" land speed racing track. The Yancy Bud Busa is the only bike to hold the track record at two major land-speed racing tracks at the same time.

  10. I didn't really think of this, I'm more concerned of the "filtration" ability, and is it really as good as Scott promotes? I let the dealer take care of the oil change but why do you think he suggested I stick with OEM? Thanks for your response, it make sense.

    Here are the standard replies.

    1. The OEM Honda filter has have a valve that does not allow the oil to drain back into the engine. You don't know if that is true on your replacement filter. (engine wear issue)

    2. The OEM filter has a bypass spring specified by Honda. The bypass spring in the replacement filter may not be setup to bypass at that same pressure level. (possible engine damage issue)

    3. The generic filter may not filter per Honda specs. (engine wear issue)

    (NOTE: The shop guy does not know what the specs are for the Honda filter any more than you or I do.)

    4. Your service guy didn't want to spend the time cleaning your new replaceable filter. (an oil change is a flat rate charge and it doesn't include time spent cleaning an aftermarket filter)

    5. The service dept. didn't get to sell you a new filter. (dealer revenue issue)

  11. After 40,000 some miles, I decided that I should take a look at the valves. The result? I had one valve that was borderline tight, but within specs, and 10 valves that were out of spec loose and needed adjustment.

    I didn't expect that.

  12. When the Reg/Rec fails, most of the time, your system overcharges.

    Limiting voltage is the primary job of the Reg/Rec. That's why they get so hot.

    Symptoms include blown light bulbs, (dash bulbs go first) and a cooked battery.

  13. Been there, done that. Still have the scars.

    Don't waste you money trying to rebuild and refit old crap. Keep in mind that CBR 900 and 600 owners are replacing their shocks with something better. Do yourself a favor, save up your coin and buy a good, new fully adjustable aftermarket shock that is set up just for you and your riding style.

  14. The RR does need to dump heat to the frame, and Honda supplies a big flat mounting pad for just that reason. Don't relocate. It probably wouldn't hurt to use some of that grease that they use between a computer heat sink and the chasis when you mount up a new RR. (or, do it just as a maintanence project on the one you have)

    I replaced my OEM (still working at 37,000 miles) RR with one of the replacement units that is finned. I do throw my original part in my tank bag when I go on a long trip.

  15. I had my valves checked at 28,000 km and they were well within spec. This is an expensive service in Vancouver [$340CAD incl tax]. Is there any sound or feel that indicates when they are too tight [i am assuming they get tighter as the shims wear]? I just hate to pay that much when I oculd go 100,000 km without adjustments needed. On the other hand, having a piston hit a valve doesn't thrill me either.

    The valve adjustment in motorcycles that use shims usually get tighter, but not because of wear on the shims. It is because the valve itself tends to distort and "tulip". If they distort enough, they still won't hit the piston, but they will quit sealing properly, and you will loose compression.

  16. The only substitute for cubic inches is rectangular dollars.

    There are a few guys on this board who have modified their birds to the point that they can beat a majority of the Busa's that they come up against, but don't forget, there's a ton of hop up goodies available for the big Suzuki, and not much for the Honda.

    There are probably more modified Busa's running around in the US than all the BlackBirds combined.

  17. My OEM chain lasted about 18,000. It was near the replace marks. I replaced the OEM chain with a mail order D.I.D. right before a hard trip to SanDiego and back. The new chain went bad on the way to San Diego even though I lubed it at every third gas stop. (it developed kinks and tight spots) but I ran it for at least another thousand miles after I returned home. I gave the chain to "a friend" who owned a local shop. He was supposed to give the chain to the D.I.D. rep, but never heard anything. I don't deal with that shop any more.

    I was concerned about damage from the bad chain to my OEM sprockets, so I replaced everything with an AFAM kit. I bought it from "my friend". It was the same kit that is in the sprocket center link.

    This chain has held up well. It has about 18,000 miles on it and is no where near the wear limits. I don't think I needed to adjust it at all this past riding season. I didn't even change the adjustment when I replaced my rear tire.

    Just lucky on this one I guess.
