Oil and crankcase seals

yes mate it's the left crank seal. Might as well change the crank bearings while you're at it.

Harry,

The seals are removed to the inside so you will need to split the cases and pull the crank.

You will need a set of gaskets.

While you are there you may as well replace all of the seals and bearings for the gearbox. (saves having to split the cases again at a later date.)

It is more than a 1 beer job.

If the crankcase is the same as the non oil injected bikes sold here in Canada and the USA you may want to check into a common problem that Kawi had with oil leaking into the ignition area.Check the area around the outer part of the seal,there are 3 slots around the outer part of the seal, if the outer bearing sleeve is exposed that is cast into the case half then the oil is most likely slowly bleeding thru from the crank side into the ignition cover.This is caused by the different expansion rates of the two different metals.The solution is a simple one,just lay the bike on the right side,clean the slots with a degreaser,rubbing alcohol will work,mix up some JB weld(metal based epoxy) and fill the slots with the epoxy,you may want to do a leak down test on the motor just in case,it will reveal if the seal is actually gone.
