Anyone using these new Hotcams, wondering what stage ( 1 or 2 ) you went with and what you think of the performance.

Map changes?

I have stage 1s in my 250 and 450. They do what they say they will. The 250 i build from boxes, so i never rode it before the cams. The 450 has almost too much bottom. And the remap i got with it made even more fun. I like them. Only thing that was weird at first was getting used to valve noise. They are loud and have their own valve lash values that are different from stock.

Humm.. was leaning toward stage 2, as I think the bike needs a little help up top. 4hrs on a stock engine with a FMF 4.1

FYI: I have found that using the OEM valve clearances works best. I tried the Hot Cams specs and found the engine to be very hard to start as they were tighter than OEM.
I liked the stage 1 on my Honda CRF450R. I liked the stage 2 on my YZ250F.
