1982 Clutch Cover diffrences

So I have both a 250 and a 430 XC. I would think they would have the same Clutch Cover but they don't. The 250 has some sort of domahicky below the Kickstarter and the 430 dosn't. The 430 has a Vent Hose but the the 250 dosn't. One or the other probably isn't an 82 or is there really a diffrence between a 250 and 430??? Oh and Yes I'm in need of one of these if anybody has a line on one.

Sounds like the one on your 250 is off of a 510 four stroke with the whatchamacallit being for a decompressionlater, fun aside it think it is really for a four stroke. 250-500 clutch covers are all the same but all should have a vent.

They are a common sought after used part. I think they are being repopped but I have heard of quality/fit issues.

They tend to crack at the rear locating pin or get damaged in crashes. Somewhere around 1986 they added another bolt which pretty much stopped the cracking at the real locating pin but by then they had a water pump cast in. Not aware if anyone has actually tried to see if the Italian four stroke covers will work. They moved the water pump up to the cam and added still another bolt hole but they probably will fit and look better than one with a capped off water pump base.
