kevin j Posted September 24, 2007 Report Share Posted September 24, 2007 I can't comment about 250, but the 350 mono is turtle slow on response both up & down due to the flywheel. Common mod is take off half the outer ring and it helps alot. some take all the ring off, but it vibrates alot more. I take off half to 60%, biggest change is on shutdown, say at top of a bank or something. The whole flywheel takes you on forever, the trimmed version is a bit more modern feeling. kcj Quote Link to comment Share on other sites More sharing options...
benj Posted September 24, 2007 Report Share Posted September 24, 2007 i had one of these for a few years. the throttle reponse on mine was the same, not sure if it was suposed to do it but it never let me down. i never trialed it so it wasnt such a problem for me but i think its normal on those.

kevin j Posted September 30, 2007 Report Share Posted September 30, 2007 forgot to note: You can get around it by using the clutch a lot more. I came off the street, tended to ride old style, no stop, with throttle only. Took a lot of instruction (i.e.nagging) from friends to learn slipping the clutch doesn't hurt it. The TY I had had a 19 year old clutch original, so they can take it! Quote Link to comment Share on other sites More sharing options...
