Engine Balance

[Outrage 19]

I have heard if you have scores in just one cylinder you only have to bore that cylinder. Doesn’t that throw the balance of the engine off because of the extra weight in that one oversized piston?

Re: Engine Balance

The oversized pistons are within tolerance of the standard pistons. If the others measure out OK then yes, you can oversize one cylinder.<br /><br />There have been several very good threads on the subject.<br /><br />Good luck!

Re: Engine Balance

Youre welcome. Hope that helps.<br /><br />Oh - the biggest and most important thing is to figure out why it scored a piston. We dont want a repeat situation.<br /><br />Good luck!

Re: Engine Balance

I believe a bent reed valve caused one cylinder to lean out. Thanks again
