wr with yz/lighter flywheel??

wr stuff

looked into small wr fly wheel two years ago..............where do you get one ?



so. how did your yz cam work out ? I was cautioned to beware less low end for small increase in top end.

tried several exhaust systems, using 07 yz muffler with fmf head pipe right now.

Will see you at the summit for easter to compare the cams v/s stock cams with the yosh exhaust. Mine turned into a tractor pulls stumps from the very bottom through the midrange with a bit more up top but really shines through the midrange, can run a gear high now even in the pow. I ended up gearing it up so it just pulls 5th in hardback still no problem in 1.5 feet of fresh up high in the Hoodoos Arcticman did not disappoint was the best snow in the north so far. :face-icon-small-hap
