I would start by making sure the valves are in spec, there are how to's for the valves listed within the forum. Also ensure that your cam chain has the appropriate tension, its a pretty straight forward procedure. Doing both of the above will save you a lot of heartache down the road !

I would certainly pull apart the carb ensure that your jets are nice and clean. I had a problem with my low speed jet getting clogged repeatedly as gunk ran out of the lines and the carb after running it for the first time in 7 years !

By the way I am in NC as well, if you are in the Raleigh area and you need assistance let me know. I am not a pro but I rebuilt my XR pretty much from the ground up.

Valve clearance on stock motor is 0.05mm or 0.002" for both intake and exhaust. I highly recommend getting a clymer manual. Check amazon or ebay. It will make your life much easier.

According to some, Pre CDI flywheel's are noted for being difficult to keep tight on the crank (probably because a very few people actually have the correct tool to hold the flywheel while torquing down the nut). Socalxr has mentioned the problem here many times.

If you're buying a manual, the Clymer tends to be a little easier to navigate than the OE.
