I'm haveing trouble with my "new to me" 1975 XS650. When I bought it the right cylinder would not idle. It would kick in arould 2500 rpms and run ok, but when just cruising at 50 mph or less the right side would just kind of gurgle. Under power it ran good. Me and a very experienced mechanic went through everything for about 6 hours today. Timing, valves, points, carbs... The previous owner had rebuilt the carbs a while ago and told me the right cylinder ran rich, Boy does it! When it idles for a short time the right side smokes like crazy and when I pull the plug it's soaked with gas.
We took both carbs down a dozen times. The previous owner had saved all the factory carb parts when he rebuilt them so we put them back to stock. The needles in the rebuitd kit that he had used were about 1/8" shorter then the stock ones. After we put them back together the left ran GREAT, better then with the rebuild kit parts but the right side ran the same.
I'm at my wits end. Anybody ran into this before?
I'm begining to think the right carb has a cracked passage somewhere. That being said, I guess I'm looking for a right carb body for a '75 XS if anybody's got one laying around.
Thanks...
