Hey, I have a '86 XT350 :) I'm currently rebuilding the entire bike. I would also recommend Bike Bandit. I ordered a Master Cylinder parts kit, it was just what I needed!! They can get almost any OEM part for the XT350's. Another good thing is that they have a flat rate of $6 shipping.
BTW.... Does anyone know where I can get some new fork boots? (that are NOT OEM) I really don't want to pay $100 for new OEM boots...thats just ridiculous! I saw some cheap ones on Evil-Bay but I'm not sure of they'll be long enough when I get my forks/bike back together. The OEM boots I have right now are about 12'' long, but I'm not sure if thats just because they have been stretched or not... The ones on Evil-Bay are 11'' long, but I'm not sure if they will work or not.... Anyone want to give some insight on this matter ? :)
