Hey Everyone, as you might know (from an previous post of mine) I have a new 05 WR450. So far i have not had a chance to get it dirty (love that new bike smell) I really want to dial it in first. So far i have clipped gray wire, Put on the pro circut 496 pipe, opened air box (including cutting holes in right side) and jetted with JD. The bike has of course really come alive. 2 things, after checking on here I'm not sure if cutting the blue wire is still necessary and JD's kit says to put clip on 3rd groove for wr and 4th groove for yz. Does anybody know why, if i do yz timing should i go 4th groove..... Well i went with 4th groove and did not do yz timing and the bike runs great. I have an area that i test ride but still have not got it dirty yet, i soooooo clean and pretty i don't want to ..... well yes i do, get it dirty that is Maybe this weekend.
