After 6 track days my GK73 sp is a little err .....smokey, any forum experts down south fancy fixing it for me ?

That's a nice looking bike!
Shame about the smoke though, I rebuilt a couple of 76a motors a few years ago and it ain't cheap......

Could be rings or valve seals or its running very rich. What colour is the smoke? When does it smoke?

Cant be arsed to do it my self to many 2 strokes in pieces in the man cave. only smokes at the top of the rpm range and between gear changes, quite low miles so think its valve guides, its def running rich too. feels like it has about 40 hp

Not good reading......

Hope it was fixed before i bought it as this wasn't mentioned at all......

How's the bike riding?
