Above 6k is a 14.1-1 compression dome. I am putting one of those on myself. Did the drop-in kit this year.

I talked to Kelsey(RKT) about mine today and he told me it was 14.8to1. JDU what are you gonna run for gas. I'm gonna mix 3gal. Av-gas per tank.

Half the areas I ride I am high enough ill just run 91 or 93. The other half will mix a few gallons avgas.

What elevation you ride? I am 6500-11k.

I ride from 7400+, I've had the PTO side go down twice in 2 seasons,the first time I was jetted at 360. The sec. time I was at 370 and I rode the whole season with no probs. last ride 4-2-2010 it went down again. I think our gas SUCKS.

Both of those failures on the drop-in? You running forged or cast?

Ya, both with DIK, first ones I will take the blame (jetting I guess) but the second time I'm not sure yet. As far as cast/forged IDK all I know is they were his latest ones for last season.
