i guess if your only at 800 feet, it makes sense you're hitting 14 psi. im abou 12 at 6000 feet with the 22/31 setup. runnning about 8800 rpm with my clutching. what a re you using for clutching around your area? i tried a bunch and couldnt get anything to work well here (1800 feet). i tried a few different kinds of weights and none seemed to be very good. thanks

I am running the STM weights, what do you mean by not like? And what have you run?

Thank you Skydog

trid a few different yamaha weights, cant remember which ones anymore. also tried a bunch of different sec. setups too. could get it to pull good on hard, but lose too much rpm in the soft. couldnt get it right with any setup. guess i'll keep trying, thanks skydog.
