retromlc Posted June 7, 2020 Report Share Posted June 7, 2020 Maybe sucking in air? Or the throttle cable had dislodged? Was the smoke.from exhaust overly white or did it stink as if it was burning gearbox oil? Quote Link to comment Share on other sites More sharing options...
Chris Chapman Posted June 7, 2020 Author Report Share Posted June 7, 2020 The smoke looked fine from the exhaust and yeah someone else also said could it be drawing air and the throttle is nice and feels nice to use and free I was just hoping many some how it's over heated and not liked it and revved up when it's got so hot as I noticed the fan not working but I started it afew days after not for long but it seemed all fine but I dont know if I dair take it out for the day to see what it's like or if that's a bad idea?

trapezeartist Posted June 9, 2020 Report Share Posted June 9, 2020 If you’re concerned about damage from overheating, take off the exhaust front pipe and look up the port at the piston. If it has nipped you’ll see scoring on the piston skirt. To be even more thorough take off the head to check the piston crown, ring land and the sealing of the head gasket. However I can’t see how overheating could make the revs run away. Quote Link to comment Share on other sites More sharing options...
