RE: STS Engines
1/2 gallon after break in and she is starting to sing now, i cut some ports on the sleeve to get some flow in there and it was flying around the track, temps were about 240ish so far but could be richer bun nah, its good now. i fried a clutch spring along the way so had to pack up but i'll post more as i go. when i was working on the sleeve i noticed a mirror finish inside where the piston rides, none of my other engines looked like that, always a bit more gritty looking.
