oh crap!
So I took off the side cover that covers the flywheel in order to give the flywheel weight a check that the set screws are snug and all is well.
There was about a tablespoon of oil in the bottom of the cover, so I guess the crankseal is leaking. Wonderful, after looking at the repair manual the cases have to be split to replace the seal- is that correct? 97 220.

if you use wet/dry paper, i dont see how any grit would come off. like i said, ive never done it to crank seals, so i dont know. next time one of my crankseal is leaking, ill try it........that way its my motor if something dont work out. i think it would work tho.

This is just my experience, but leaking main seals usually indicates play/slop in the main bearing. When the crank end is spinning somewhat oblong, it becomes very difficult for the seal to maintain contact, and you get a leak. This is why it never bothered me that KAW designed this bike in such a way as it has to be split to change seals. If you're changing seals, you should probably be replacing main bearings as well. Just makes sense.....

as far as mains.... I get a good tight grip on the flywheel and there is NO play whatsoever. That was the first thing I was concerned about & I think the mains are somwhat OK.
This just sucks because I just don't have the extra time to do this. Between work travel kids and "stuff", free time is limited.
Are there any tips or vids that have been posted here on splitting cases, etc? It would help alot!
Thanks!

I don't always agree with Juliend, but this time I have to say that I couldn't agree more! Change the bearings and seals!juliend wrote:This is just my experience, but leaking main seals usually indicates play/slop in the main bearing.

This is not the terrible job that most people think it is, it is really quite straight forward and a bearing/seal kit is pretty cheap really.

oh crap.... Updated-
Well, I've decided if I have to yank the motor & split it, I might as well just do it right and rebuild the whole motor.
The topend hasn't been done since we bought it 3 yrs ago, so what the hell, it's only money.
Details to follow as soon as the parts are ordered and I roll up my sleeves to get my ass moving.
