CS Seal Leak, '78 TS185
My original 1978 Suzuki TS185C has a small oil leak. After sitting for a week or two, there will be some oil on the bottom of the shift lever. I removed the left cover, cleaned everything out, retested, and it appears to be transmission oil (10W40), and not 2-stroke oil, so I'm guessing that it's coming from the countershaft seal, behind the sprocket.
Can this seal be replaced from the outside, or do the cases need to be split in order to get at it?
Thanks in advance for any advise/suggestions.
