it's a early gen not the later gen Yamaha xs1100 and the timing chain tensioner doesn't seem to be doing it's job. I looked at the rubber stopper which was leaking. the compression was good when I got it I synced the carbs- then I lent the tool to someone- I don't think the carbs are messed up but it doesn't idle perfectly and the radio gets quiet when the engine is on. I think there is something wrong with the timing chain adjuster which is on the front of the bike. the upper two or three thousand rpm is lacking in comparison the lower rpm rush.
