My setup: 2013 WR450F. Comp ECU Various FI maps attempted (going for increasing range). FMF Q4 pipe. Stock gearing, stock sprockets. Stock air filters. I'm being advised by some local shop mechanics that, if I want to smooth out the "on / off" switch-like power delivery from my stock motor, that I should also consider a heavier flywheel, or a Rekluse clutch. I know what the clutch is for, and I'm considering that for a different reason (I'm not yet skilled with a clutch on steep terrain, and it might help take some training time off me, at a price). But the flywheel idea. Should I consider installing that? The power delivery seems very abrupt. So much so, that twice now it's darn near thrown me off the back of the cycle. I'm on the bars, focused, not drifting, and paying attention. I hit a bump, which causes my hand to "blip" open the throttle. The cycle leaps forward(!) and I'm heading off the back, suddenly, and quite unexpectedly. Once was very, *very* close. It happened again, and that time I was ready for it. But, it's un-nerving. I'm like, stop that! Would a heavier flywheel be a good solution for me? Anything else you want to recommend (other than more training, I've got professional training scheduled and on the way...).
