Default Re: Engine max went from 34mph to 25mph? wth?

i found out you need to check the head nuts too for air leaks, because they're not always sealed off, if you have too large of washers under the head nuts then air can go through there and cause minor problems. i solved this problem by drilling the perfect size hole in four pennies. (which are soft enough to seal well) i also re torqued my head nuts slightly after the first 4 warm ups because if there isn't enough pressure the gaskets will burn out and the threads are too week to get it tight enough the first time.
its only too fast if you cant stay on!
