Hi, this is my first post. This forum is awesome and has been very useful. Just bought an 2002 LC4 couple of weeks ago and it is my first dual-sport/dirtbike. So here is my problem. I traced an oil leak to the sprocket seal (pretty bad one). So I read Creeper's guide to changing the seal and Meat Popsicle's guide to replace the chain. Great , now I know what to do! However, when I inspected my bike I found that the bolt is tight, but the spring washer is completely loose and the sprocket has a few mm of axial play on the shaft. Is this normal? (I don't think so from reading the guides) I also noticed that the chain is grinding :eek1 on the metal guide for the cover. So I counted and I have a 16T front sprocket and a 42T rear one with a DID 520 VM chain (covered in bits of metal). Isn't this the stock configuration? Why is it grinding? The guide is stamped 15/16T! I don't know if it matters but the bike came with Talon Hubs. I will take this apart as soon as I get some of that Loctite. Thanks for your help.
