Hey guys.
This fall my '79 Xs was popping fairly badly and pulling some heavy vacuum through the right side carb. I suspected a burnt valve or something of the like when i stored it for the winter. Well here i am getting the itch to ride on the nice MN days were getting. So today i pulled the motor from the frame and have proceeded to take the head cover and the head off. The right side head looks pretty dirty and crummy compared to the left. I currently have parts washer fluid in both heads to see if any is leaking past the seats to indicate a bad valve/seat. Early indication seems to be pointing to the right intake to be letting a little by. Anyways just wonder if you guys have dealt with anything like this. Looking for some insight because this is the farthest i have dug into this motor, i've done rebuilds befoer but never on the XS. Do you guys have any suggestions on what else to check while im this deep? I've heard that replacing the front cam chain guide would be a good idea? What about replacing the cam chain? Let me know anything that ya'll would suggest! Thanks guys!
