scotty97 Posted September 11, 2009 Report Share Posted September 11, 2009 A mate of mine has just bought a 1996 gasser JTR270 and we've noticed that it has a slapping sound coming from the engine, it sounds like the piston is slapping something but the bike has plenty of compression and plenty of power, it starts first kick every time and everything else seems fine. Anybody heard this before and can point us in the right direction????????????????????? Quote Link to comment Share on other sites More sharing options...

t-shock 250 Posted September 15, 2009 Report Share Posted September 15, 2009 It's a 13 year old bike, could be anything to be honest. Almost impossible to diagnose over the internet. Quote Link to comment Share on other sites More sharing options...
peterb Posted September 16, 2009 Report Share Posted September 16, 2009 Hi scotty, I would suggest a new piston kit from this info, I think these may only be available in A and B sizes, go for the B if available. Bye, PeterB. Quote Link to comment Share on other sites More sharing options...
