weak spark on right side

[piperraider]

Have spark on both right side cylinders,but if i pull plug caps off it doesnt change the way bike runs,if i pull left side cap off bike will stall.Right side exhaust gets hot when running,but not as fast as left side does.

You sure it's spark your missing? Could be the carbs are plugged?

Sounds like carbs are out of synch, left side is doing all the work at idle...

I had a similar issue with the left hand side. Ended up pulling the HT lead off the coil and using side cutters, trimming about 10mm off the end and reconnected it. The seemingly better connection has sorted it and I have a much better spark

Check you connections at the coils. I had one of the leads inside the plug get pushed rearward and was actually unplugged even though the plug was seated. If that doesn't fix the problem, take your air box off, start the bike and see if you can see the slides moving equally and if you see gas in each carb squinting when you give it gas.
