900 king cat

Sure we do, did you ask for help?

I don't see where you are asking for any advise? Also need more info to help you out. I got a pretty good take on mine, but have no idea what advise to give for some guy in montana, at 10k feet. Good Luck! -00's
 
Just ask.........

Let's asume that your engine is tuned right. Then for mountain riding in Boseman area, you should be able to run 66 gram primary with 52 deg helix and green sno-pro sping in the secondary. What else do you want to know?
Or 49 deg helix and a red/white secondary.almost as good.

68 gram stock ti spring
51 helix cutler red white (same as cat green)

I am ported and running a single at 8000-10000 feet.
 
what I run

I have a 162 x 2.5, CPI single pipe and can, VF3 reeds, .015 off the heads (135 psi) oliver drop brackets, poweder pros.

I have 69 gm stock weights, stock front spring, red white cutler in the rear (not quite as stiffas the Sno Pro green, 49 helix.

jets are at 350s (I know most say 400+) I ride 6000-10000.

but the biggest trick by far is re-gearing to 19/45. I will go 19/46 next. it makes it a climbing MONSTER.

I weigh 250 + gear so that while swinging a big track might be the reason but it made a HUGE gain. Highly recommended. If you would want my 45 let me know I want a 46, 4 rides on it, my old 43 had about 100-110 rides and was still pristine so this will be immaculate also!
