high compression

[renegade805]

Motor is worked and a national motor compression test 185psi. Seems real high should I be worried. Motor is tight leak down passed 4 races since rebuild

That's not too high...run race fuel if ur not

Yea motor only runs on race gas

Thats about right for a 15cc head set up for race fuel.

if you ever plan on running it on anything other then race fuel you had better grab a second head and cut it or mill it to 17cc
