gunner88 Posted May 18, 2015 Report Share Posted May 18, 2015 Blew the top end in my banshee. Right side piston is demolished. Not sure if its been blown or bored before, I just picked it up a few months ago. Is there marks on the top of the pistons to indicate the size? Also should I split my case to remove the small pieces of aluminum from the piston? Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted May 19, 2015 Report Share Posted May 19, 2015 Yes (maybe) on the split. Have it measured for out of round and taper. If more than half accepable tolerance, bore it. Quote Link to comment Share on other sites More sharing options...
98_sheester Posted May 19, 2015 Report Share Posted May 19, 2015 Yup if its stock piston should start with a "513" but if you can put that number on here we can tell you the piston size Quote Link to comment Share on other sites More sharing options...
camp0429 Posted May 19, 2015 Report Share Posted May 19, 2015 If your keepin it, I would send crank and cylinders to builder of your choice, let them tell you if your crank needs work and what needs to happen with your cylinders. Be a good time to port it if it aint already Quote Link to comment Share on other sites More sharing options...

gunner88 Posted May 20, 2015 Author Report Share Posted May 20, 2015 Right a treasure hunt. I wanted to avoid splitting the case until this winter. Mainly because I don't know what I'm getting in to. Probably not a good tho Quote Link to comment Share on other sites More sharing options...
