Picked up a secondhand ride a few months back and after awhile I finally have the time to start tearing it down and really looking into things. One of the biggest issues I noticed with the bike was that when I first try to take off it seems like it takes a good bit up into the rpm band before the clutch will finally grab. Just pulled off the belt/clutch cover today and the first thing I noticed was that it seemed to have a good bit of a tacky buildup in the housing. (I'm sort of guessing that it might have been residue from a previously worn belt though, so I'm not terribly worried about it.) Pulled off my primary and secondary, but beyond that point I'm pretty clueless. I know if I dig a little further I'll find the wet basket, I believe it's called. At this point I'm just mostly curious if it sounds like something is worn, or maybe an aftermarket clutch kit would be a good idea. (It is sitting on 27's atm, not too sure what comes factory.) If you suggest a clutch kit, what brand?
Alright, thanks. Didn't even think of that. Question about the roller weights. Is there supposed to be anything to lube them or is that whole part of the case supposed to be dry? My brother mentioned that he read somewhere that the rollers are supposed to be greased.
You should also be certain that it has wet clutch compatible oil in the crank case. If you don't know and previous owner put in the wrong oil, you could be experiencing slip caused by wrong oil. If I wasn't sure, I'd change to the correct oil.
As long as it is a dry/tacky buildup, I wouldnt be too worried, but if it is oily, I would be looking at the seal behind the primary clutch. It is a VERY common issue on bikes of that era.
Okay, cool. Looks like I'm all set. The buildup is dry and tacky like you mentioned. I'll be cleaning the case out and getting it put back together today. Oil was already drained with plans to change as well, so that's no big deal.
