Grandpa,
Bartman is right. I'm selling my streetbike on traderonline.com, and I thought I'd see how many Raptors were out there, I must have counted ~20 of them. Quite a few of them were in the east, but it would be worth a look.

 

I weigh 140 pound and all my friends are 230+ so I would guess that has alot more to do with being faster than running lean. The after they installed the last engine they jetted UP to be sure it was not that but at 5500+ feet most of the time it was running rich. Plug color was good and no overheating problems. I still think it was just plain BAD LUCK ; )

 

Thanks...Check out this Raptor Ad On Traderonline

Jeez,
That guy should lay off the crack pipe for a few minutes. fmf fatties on a 4 strock eh? 120mph raptor, (nitro no less) for 2k. And what the heck is a dyno gear?? I hear crystal is real popular in showlow, maybe that's the deal.

 

Has Yamaha been doing the work under waranty?
