jamietzr250r Posted August 26, 2007 Share Posted August 26, 2007 sounds like an electrical problem to me, how has it been derestricted? this could be part of the problem. Link to comment Share on other sites More sharing options...

yoda Posted August 27, 2007 Share Posted August 27, 2007 It sounds more like piston siezure. It is possible that the fuel /oil ratio is wrong and causing a problem. Link to comment Share on other sites More sharing options...
