olmick Posted December 15, 2006 Report Posted December 15, 2006 (edited) Well i was crusing at about 65 or so trying to keep up with the 4 strokes, raced my buddy again and the shee fell flat on its face, so the left side started backfiring pretty bad, did a compression test and the right side was 127lbs and the left was 62lbs , so i tore it down and got this: http://i53.photobucket.com/albums/g57/mick...28/100_0651.jpg http://i53.photobucket.com/albums/g57/mick...28/100_0643.jpg http://i53.photobucket.com/albums/g57/mick...28/100_0631.jpg my question is how can i get the piston crap out of the exhaust port, its in there pretty thick?

BigRed350x Posted December 15, 2006 Report Posted December 15, 2006 Probably wouldn't be a bad idea to split your cases and check your crank bearings for debris as well. That looks icky. Rod bearings could have crap in them... all sorts of fun stuff. Looks like it got hot and brittle and the top of the piston snapped off. Lean? Your cylinder probably needs bored, you MIGHT get lucky and have a hone clean it up, but check your piston/cylinder wall clearances and ring end gap when you get it put back together and make sure its ok. As for getting the stuff out... dunno man. If you don't have porting tools to clean it up a little bit, maybe a lot of hard work and some fine sandpaper? LOL Might be best just to send it off to get the next over-bore and whoever does the bore job should make sure its cleaned up before they give it back to you. Quote

Looks like you need to get a bore job, I agree that you also need to split your cases and check out your crank bearings Quote
