So when you run your finger around the inside of the cylinder on the walls or around the outside of the piston you don't feel scratches . That's good. Unfortunately all the pictures you posted showed the same view of the piston and the same angle of the cylinder. All the cylinder pics were looking at the intake port. None of the exhaust port . Same with the piston. All were looking towards the piston form the fly wheel side.:ROFLMAO::ROFLMAO: The big thing is you shouldn't feel any scratches. You should see the cross hatch pattern in the cylinder walls which is normal.

Don't sand the cylinder walls. You need the cross hatch pattern ( those fine micro scratches) for the ring to seal against, works with the oil in the fuel. If you sand anything just the edges of the port openings.

Hard to tell because of the shadow. It would be nice to know where the ring was pinched between the piston and cylinder.

Thats what i meant...just sand the edges and make sure they are smooth

Your piston looks fine to me. Your transfer bridge (the part were all worried about) I could go either way.... still really hard to tell from the pics. But it almost looks like it's been tweaked a bit.

Yea it almost looks twisted. I don think the piston is ever gonna slide smoothly across that. Probably eat the ring up in that spot too

1000 grit sandpaper and wd40..is it alright to do the same with piston ..because there a scratch that didn't show in the pics.

I'll post the result once I get the ring ..then if it doesn't work out .i'll buy a new cylinder and piston and will have learned something new.all this is the result of overtightening the the muffler bolt..one ldad's to another.peace

ok i hear that..its probable that both the head and the piston is jacked after my sanding job. ebay seller danic 4 ..i believe he has the right replacements ..55.00 bucks .so stay positive its gonna happen.
 
Well as we all know with the holiday season setting in on us it can get really busy... heck ingot the high flow fuel lines and body wrap for the DBXL and haven't even had a chance to take them out of the boxes to post up some pics.
 
Well.... we had Thanksgiving then hunting season. That ended this past Saturday. Not to mention work and a 2 year old and 2 month old?. Now its Christmas season and the wife wants to spend all my money. And it's cold out. Just gets to be a little much at times
