right side not firing on all three cylinders

[La.F6/X]

Ok went for a quick ride this evening and the right bank does not seem to be firing all the time, you can  feel the power change when she hits on all 6 cylinders. What could be wrong??? Coil, wires ???Any help
Thanks in advance

Try the easy stuff first.  Change the plugs and see if that cures it.

If it happens to be intermittent, check the input connections at the coil.

[Dave Weaver]

wouldn't think it is coil problem, there are three coils and each on feeds 2 cylinders

A bit more information might help find the problem. You mentioned that it sometimes fires on all cyclinders is the problem only at low speed? Will all cylinders fire with the choke on?
If the answers to these questions is yes, you have clogged slow jets.

Sure sounds like varnished low jets,, get yourself some Sea-Foam.. A full can per tank and run several tanks thru it.. As your running it keep slowing down until it begins to run poorly and keep it there until it starts to clear up, then slow down some more..

[La.F6/X]

Run a whole can in 5 gals of gas?? But the clogged slow jets could be the problem It does seam to run better with the choke on.
But I still have 1 question, why would only the right cylinders be running poor??

Thanks for the advise will try some sea-foam today. one more question can the carb bowls be pulled with the carb still on the bike?

Because the right side is high on the Kickstand so the fuel is at a different level .

[John U.]

Yes, the bowls can be romoved with the carb bank in place. You can tie up one side at a time with the intake tubes, tank and airbox removed. It helps to have the bike on a lift. A mirror and flashlight will be needed as well.
First drain the carb bowls, try Seafoam as reccommended (Techron works better IMHO).
Give the carb vleaner some time to work, an even stronger dose (full can to 1/2 tnak or less) won't hurt. Run it and let it sit for a few hours run it again. let it sit over night. If that won't do it get the wrenches out.

Yep, to what John said.. Good heavy doses of Sea-Foam may be what is needed.. If that doesn't help, its time to get your hands dirty.. I would rather pull the bowls off the offending carburetor than remove the whole assembly.. Some compressed air and a good spray carb cleaner like Deep-Creep[spray made by  sea-foam]and a tag wire or number drills will work..Its not that bad a job..The reason we believe it to be a low jet carburetor issue is that this is a fairly common problem and that the ignition system uses 1 coil to fire the 2 cylinders opposite one another[1 and 2; 3 and 4; 5 and 6] so that pretty much rules out an ignition problem..

[Ricky-D]

Yup, can't say it enough.  Try everything first before removing the carburetors or making any adjustments.

The fact that it is happening to the three carburetors on the right side is very telling.

The common factor is clearly evident that it is a gasoline problem and not an ignition problem.

This is not the first time that this problem has been reported on this forum. You can research it!

Seafoam or Techron or any others is indicated, and in massive doses, repeated until it clears up.

I have a question.. Why do parts of some posts appear 'lined out' ?? Is some one doing that or is it one of lifes little wonderments ??

[Chrisj CMA]

Most likely carbs as mentioned, however there if one ingnition pulse generator is bad or gapped just a tad to far it may be intermittent and there is one for each head I believe they fire juice to three plugs each

Because someone hit the strikethru button LOL
