I recently came across a 1982 SR250J Exciter, in great asthetic condition, but not runnning. It had sat for nearly 5 years with the same quarter tank of gas, and was rarely run (only 2600 miles). I've cleaned the tank and replaced the fuel filter; replaced a few gaskets. Everyone with this bike seems to be looking for tech info, and I honestly cant find anyone still publishing the service manual. I really need the torque specs for the head, I would be running in no time if I could find just these things. I have all the gaskets from the bottom of the head up, i just dont want to re-assemble it half-assed. If anyone knows where I could pick up a manual or would know the specifications for assembly they would be much appreciated.
