Hello all, I am new to this forum so please, be gentle...hehe. Over the past year I have been building a noyce TRX500r for MX, it is at its final stages, but I am having a problem with vibration (I know go figure) and need help from you guys who have already crossed this bridge (possibly you DIER-Wolf???? and whoever else). My quad is done right, A Laegar 250r based frame built by Mike Laegar himself for the CR500 motor, totally rubber mounted and everything (only 5 of these frames were ever built by him), rubber isolated steering shaft, 98 CR500 crate engine, Paul Turner pipe, hand-built for this quad specifically, JRD No-link swingarm with Elka shock, once again built for this quad specifically, etc, etc, etc. Even with ALL of the precautions taken from the getgo with this quad, the vibration is much better, but STILL not good enough to ride for extended periods of time. So this is where you guys come in (I hope) I know at this point, I am sure that there is nothing else I can do external of the motor, my question to those of you who know, what needs to be done internally???? I imagine the replies will be centered around balancing but how specifically??? How much will it improve??? I am at my last straw, if you guys can't help I give up, I just re-fabricated the steering stem 5 different ways to try and cure the handlebar vibration and might as well just pissed in the wind. PLEASE HELP!!! Thanks in advance......
