Hey all, I bought an '82 XJ1100 Maxim, and have absolutely loved it, but the bike has been giving me a slew of issues... Brief history on the bike, I bought it off a guy for cheap. It was running and riding, albeit with quite a few problems. It ran super rich so smoke was blowing out the exhaust, and the bike wouldn't start or run if there was any choke at all on it. Plus it wouldn't start unless the engine was already HOT. So you'd be sitting there just cranking the starter in short bursts for like 5 minutes and then it would finally turn over, and you had to sit there and rev it at 2500 RPM for another minute or two to warm it up. But after that, there were virtually no problems with riding it around. Throttle was responsive, shifted smooth, idled perfectly fine, etc. I tried working on it myself a bit, but eventually passed it off to a buddy of mine who has more tools and know-how than I do. Here's a quick list of what all was done to it; Replaced coils Replaced spark plugs and spark plug caps Float needles Intake manifold gaskets Float bowl gaskets Mixture screw o-rings Cleaned and rebuilt carbs Timed the carbs I got the bike back yesterday, and upon starting it this morning, it started right up no problem. The problem NOW is the engine idling speed, and trying to ride the bike at low RPMs. When the bike is idling, it dances around between 900 and 1200 RPM. Usually sits at 900 or 1000 and then pops up to 1200 (where it should be) for less than a second. The needle just keeps jumping. Which in and of itself, I wasnt SUPER worried about. But the big problem is when I try to start moving the bike, I HAVE to rev to about 3000 RPM and keep it there, otherwise the bike will stall out in first gear. Which, when I release the clutch, does 1 of 2 things; either it goes flying like a bat out of hell because i have to crank the throttle so far, or it bogs down to about 1500 to 2000 RPM and will not go any higher no matter how hard I twist the throttle until finally it decides to start revving higher. Usually when it bogs down to that 1500 to 2000 RPM, its shaking pretty violently, and while I'm cruising at low RPMs, I can hear the exhaust quietly sputtering the whole time, almost like really quiet consistent backfires. It seems like the bike was almost running better before everything got fixed up and cleaned, although it was definitely not running as efficiently as it is now. The weather is so nice lately and I dont feel safe or confident enough in the bike to ride it on the street. Im at my wits end trying to figure out what the next step to take is, so any help from you guys would be really appreciated. Thanks!
