1982 750 xj missing at low rpms

new member here. also new owner.my '82 750 runs good at high rpms but seems to miss just off idle meaning i have to ride the clutch to get underway.does anyone have any ideas? thanks,leon

 

I am very naive about bikes, so I am probably not the guy with the best advice.

Having said that - I own an '82 XJ550. Earlier today I started it up, and fully choked, no problem. I let it warm up for a lil bit, and took off down the road. At low RPMs, it was missing and sputtering, but it ran better as the RPMs increased. I brought it back home and took the sparkplugs out only to find them all covered black (I was running really rich). I am now in the process of resyncing my carbs (on hold overnight as I have no light to see right now).

I was hoping I just needed to adjust one screw and be done with it, but each carb is independent of the others. Regardless, what you describe sounds similar to mine. I would start by looking at your plugs and see if they are blackened due to a rich mix. If not, then check the plugs to see if they are sparking. That should help shed light on what's happening.

 

Lucky:

Has this been going-on awhile ... or is it something new?

Get with us and get tuned-up.
Don't waste your Clutch when a tweak or two might set you right.

 

rick, thanks for your interest.i bought the bike recently and was told the carbs had been cleaned in the month prior to my buying it .it has good power but has missed at low rpms most of the time since i got it.leon
