As this seems to be the place for the XR500, I figured I'd post this here. I do my own maintenence, and i had a couple of questions about what should be done with these bikes, and some general questions about dirt riding. Firstly, apparently the 83 was the first year the RFVC engine was used. I've heard everything from "honda reliable" to "the rockers are made of chocolate" on these. Thoughts? Secondly...I'll be doing what will be considered "light offroad" use. I've got some new knobbies that came with the bike at the moment, the tire sizes are: Front: 3.00-21 Rear: 5.10-17 What are people's recommendations for tires? I probably won't be riding anywhere too extreme, probably 50% pavement and 50% light dirt roads. Third: What sort of maintenence should i be doing now, having no idea what kind of maintenece the PO has done? I'm figuring valves, oil, lube the shock linkages and the axels. Also, i'll be checking the rockers after the warning of a guy on another forum. Do i need to check the spokes? Thanks guys!
