Haven't posted here in awhile. The Raptor was solid this season, but the last couple races were showing some clutch problems shifting through the gears under power at the dirt races. I really had to granny shift, which is not conducive to winning or good ETs. At least I'm hoping it's the clutch... So I have new clutch guts on the way that should be a mild upgrade to the 20year old stock one in there. And since I like going faster, I ordered a Stage 2 HotCams cam and valve spring kit for it too. I'm hoping this should be good for maybe 4-5HP over stock, which is not insignificant. Hopefully take advantage of the good exhaust I already have.
And if that all goes according to plan, I will be doing something about extending the swingarm. Either making this one longer or buying an aftermarket. I'm shooting for a +4" longer arm, which should really let me launch this thing.

More to come.
