lt80 Jack I think it is. the kids kfz80 has flatspots again I'm thinking. I put 3 I think it was. what ever you told me last spring. and she has been playing in the sand. It's got a trinity pipe on it thats all. I cant rember how much your motor's are but dont think I have the cash now any way for the whole thing. she is racing flat track this winter with it and was trying to stay away from down time. can she run your clutches with stock motor? do you have them in stock? or do you need the core's up frount? will your clutch last in the sand? or will I still get flat spots every 6mo thanks for the help
