Hello first posting here about my first bike. Just bought one XS400 for 2 hundo. It needs some love which is fine cause its chilly out. I have experience building mopeds so I'm not a total newb. Also have repair manuals.
So currently the bike starts and idles. When you give it some throttle it bogs down. I figured the carbs need a tuning. While putting in new spark plugs I tested the cylinders compression. lefts at 90psi and rights 100psi. I assume it should be around 140psi. While checking the forum earlier someone mentioned cleaning the values?
I assume its the rings. Should I first plan to replacing the rings and seals, see if that improves the compress, if not dig deeper?
Thanks. I look forward to getting some feedback now and with future questions.
