I took greyracer's advice and put on the 14oz flywheel weight on my 2001 426. I took it out for 3 solid days of riding. We rode everything from washes to hill climbs to putting around with the kids. The bike ran awesome. Never stalled once, and started easier than ever. We were able to putt around with the kids, ride super technical ridgelines and bogg it down like an xr or rip up the hill climbs.
I just wonder why I didn't do this sooner. I would never go back to the stock flywheel again.
I even talked my brother into doing a 9oz on his 2005 CRF450R and the same results.
If anyone has any doubts...DON'T ! You'll love it !
Hope this helps anyone on the fence about a FWW.
