.39 mods???
 

I have a TT.39 that a main bearing disentagrated in and have a new one on the way. so i want to expirament with the old one.
i have to replace the piston and liner, con rod and bearings. orderd some ceramic bearings today, thought i might give them a try. and maybe clean up the transfer ports a little down twards the bottom end of the crank case, to enhance flow. also thought about removing the part of the liner from the rear boost port down, More flow. that way the entire rear boost port would be exposed to the piston. help reduce piston temp.

Have built some pretty Impressive jetski and snowmobile engines in the past. but havent realy done much cutting on a glow engine.

Any thaughts, oppinions, or tricks that work would be apritiated.

Wow! Ounds intense! My TT 39 already has so much power I can't imagine it putting out more. Its way stronger than an OS 32. good luck!
