MarkRoberto Posted December 1, 2008 Share Posted December 1, 2008 I'm trying to find a starter clutch rebuild kit for my '81 XS400. This would be the three rollers, springs and caps. Does anyone know where to find one in either Canada or the US? Ebay would work for me. Thanks all! Mark Link to comment Share on other sites More sharing options...

MarkRoberto Posted December 2, 2008 Author Share Posted December 2, 2008 I didn't try Yamaha. I guess I just assumed the bike was too old. Called them up and ordered the parts I need. Thanks for the tip! Now, I have another question regarding the sprocket that the clutch grips on. As you can see in the photo below, the inner bushing is proud of the hub on the sprocket. You can also see the wear marks on the outer diameter of the hub which do not go down to the bottom of the hub. My question is, should that bushing be flush with the surface of the hub so that the sprocket is fully engaged by the clutch pins/rollers? Thanks for the help everyone!

Moderator drewpy Posted December 2, 2008 Moderator Share Posted December 2, 2008 just checked a spare i have and the bush is level with the bevelled edge of the sprocket. ie approx 1mm below the surface. the wear marks you show correspond with the one I have here!! hope that helps drewps Link to comment Share on other sites More sharing options...
MarkRoberto Posted December 3, 2008 Author Share Posted December 3, 2008 Thanks Drewpy! That does help. I'll get it pushed back in and hopefully it'll work come spring. The only other thing I need to investigate once the bike is out of storage is why the starter chain has worn a groove in a couple of the ribs on the engine forward of the crankshaft. I'm hoping it's because of the bushing being pushed out but I'll have to look at it more closely once it's apart again. Here's hoping it's a short winter in Ontario this year! Cheers!

Mark there should be a chain tensioner keeping the starter chain from lashing around. this wears as well as the starter chain. Link to comment Share on other sites More sharing options...
MarkRoberto Posted December 4, 2008 Author Share Posted December 4, 2008 I just had a look at the "tensioner" - a piece of black plastic that just pops into place, right? It has wear marks on it, but I wouldn't say that they're excessive. I also don't recall noticing that the chain was loose before I took it apart and the chain itself looks like it's in pretty good shape. I'm hoping that with the new rollers in the clutch, my issues will be solved. Link to comment Share on other sites More sharing options...
