AKheathen Posted April 18, 2009 Report Share Posted April 18, 2009 my compression was at 105 psi. Somebody said that i would need a new top end soon. Does anybody know at what psi i would need a new top end? that may be. ideally, you want 120-130 at sea level, but the readings can be off due to elevation, method, and the tester that you're using. 5 psi or more difference, on the other hand; it's time for some work Quote Link to comment Share on other sites More sharing options...

swrbansheeboy Posted April 18, 2009 Report Share Posted April 18, 2009 yes, when doing a compression check you need to hold the throttle wide open. also, what type of set up are you running? if you have a stone stock engine then 105 isn't too bad, if your running a cool head with 17cc domes then 105 sucks and it's time for a rebuild.....

RagunCajun Posted April 18, 2009 Report Share Posted April 18, 2009 mods dont matter. hold it WOT and kicked the hell out of it till it dont go no more. Unscrew it and do it again to insure it had a good seal. Quote Link to comment Share on other sites More sharing options...
