A Heli-Coil can fix that problem. ...............lm

First: I never cleaned up my cylinder walls. In the right, problematic cylinder, theres a little more going on then I can just ignore. I think the metal bit protruding may be from the bad right piston. I'm going to have these professionally cleaned up, but what do I tell the machinist I need? Keep in mind the new piston and rings are not oversized.

Second: What I thought was a stretching case bolt was actually the threads in the upper case being stripped out. After putting a missing washer on the bolt and attempting to re install the bolt, it spun freely, and I ended up pulling the threading out with the bolt. The little devil on my should is saying "eh, dont worry about it, the starter motor is holding this corner of the cases together." How would you fix?

While I wait for answers, I'm going to get this little guy on the road. The neighbor kids are going to go nuts when its done!

Helicoils are pretty easy to do and the kit comes with the correct sized drill a tap and an insertion tool.

As for the bore(s) - follow LM's advice or take it to a machine shop and ask them to hone the bores.

LM,

I am going to do this, I just have to grab some muriatic acid from the hardware store. I needed muriatic acid for removing rust on the mufflers, so 2 birds with 1 stone.


You didn't mention using a 3 stone hone drill tool, and I bet theres a good reason why. I have one in my tool box.

Ya may want to try what we did with racing 2 strokes that seized a piston.
Using a good pair of rubber gloves and rag we applied straight MURIATIC ACID to remove the aluminum from the steel then washed with dish soap and lots of water.
Followed with a BALL STONE HONE. ............lm

I have both style hones but I use the BALL hone to break the ring glaze and not remove very much sleeve metal. .............lm
