    Ralph Nader explains Why early Corvairs were/are unsafe

    "A few weeks ago a young co-worker was complaining that his BMW 3-something skidded wildly and unexpectedly while he was turning coming into the dry paved parking lot. On a whim He had switched off the traction control." Very funny stuff :) Maybe he needs to drive something a bit older and...

    V-Twin Flywheels

    This is why the guys that race them will weld the crank pins to the crank(fly)wheels after they have been trued (with the lead hammer). Pretty common practice in the motorcycle world.

    Wrist Protectors

    From the look of it the Pro-Circuit bar system is just intended to reduce vibration and fatigue. The Flex-x system is probably going to be the best option to help reduce injuries on motorcycles. If you had a 4wheeler I would suggest a product called the wrist wrester that is a sliding block...

    Wrist Protectors

    :) Yea I watched the video that you had posted before. Didn't look like it was much fun, or inexpensive. Oh well that's part of racing. I do the 4 wheeler thing cause I can get the same kind of thrill and competition, while spending much less than I would on a sprint car. Scoobystu, I just...

    Split (decoupled) anti-roll bar?

    Thanks guys, I didn't realize that there was that much work being done with this idea. I like Pat's idea, or maybe a center joint with some rubber in it to make it more progressive, but I think (as John points out) it might be better suited to off road situations, where you would normally not...

    Wrist Protectors

    4 wheels won't help you either, I have broken wrists and dislocated both of my shoulders coming up short on jumps, and bashing into things. Yes Pat is correct, my 4 wheelers tend to hunt me down and pounce on me when I have a get off. :) Other than wearing some sort of "stretchy&quot...

    Convert to Methonol Fuel

    Rod, I have bee on this quest myself for the past year. I race oval track ATV's and want the extra torque that I can get from switching to methanol and upping the compression. The standard response that I get from the motor builders is "send it to us and we can do it for...

    Split (decoupled) anti-roll bar?

    I just had this idea and wanted to bounce it off of you guys. Have any of you tried or had any experience with a split anti-roll bar. What I am thinking of is something like a standard anti-roll bar that has been split in 2 with a rotating coupling in the middle. The coupling would rotate a...

    Leaded vs. Unleaded Gas

    Sounds like the lawyers wrote the owners manual for you. IMHO this was only added to the manual so that the bike would be 50 state legal. California is really starting to ratchet down on off-road bikes, which is why there isn’t a whole lot of development going on in the 2-stroke bike world any...

    Motorcycle carb tuning

    Check out the slides like Metalguy advised. I had one last week that the diaphram was not sealing properly on, and on a single cylinder it wouldn't get out of it's own way. With a 4 cylinder as you have, it wouldn't be as drastic of a difference, but would still drag the whole thing down...

    Motorcycle carb tuning

    Did you set your needle clips in the position that the instructions told you? When you put the clips on, did you count from the top groove down, or bottom up? I believe that you need to go from the top down using the dynojet instructions. How does it run at idle? If you get past your 6000...
