99 blue blaster. good eye... thanks... you are correct. you guys in the USA have SAE measurments on the bottle so I can see why you need to measure it out. But for us up here in Canada and I think almost every other country in the world our oil comes in 1L bottle with the metric measurments on them. [img]i/expressions/face-icon-small-smile.gif[/img]

First thing you gotta find where the leak is from, Start by removing the left side cover (since you will need to remove it to take off the sprocket anyway. If there is fluid around the flywheel then you have a bad main and you will need a puller to pop off the flywheel to change the main seal.If it is dry in there, remove the sprocket.
Wipe everything down cleanso you can cheak for fresh oil leaks. heck the seal may have blown completely out of the case...if not once you have the sprocket off you can start the bike back up and put it in a high gear. now just look for the oil leak as it is running.

BTW make sure there is oil in thebtranny before you start looking for a leak.
