Hi mike just had to have my collins kt100 rebuilt. I wasnt happy with what it looked like. I broke a skirt off the piston running it at 15500. Squish was too close piston hit the head. he tried to set it up for more off the turn power. maybe you have heard of the guy he has many national titles building his own kts, his name is Barry Greenzwieg, many time national champ sprint racing for coyote.
