My bike ran great for 3 weeks and has resumed stalling, surging, sputtering and backfiring. It is far worse than it was before. It will only idle when I crank it way up and stalls like crazy.

I couldn't get the surging at idle on the video as I was in traffic and didn't have much time.

Any ideas? I want this fixed once and for all as it cut off on me today while I was crossing a busy road and I am now a few bricks lighter.

The backfiring is MUCH louder this time around. Before it was a loud popping now it is like gunshots.

Do you use any gas treatment like Seafoam. A lot of times is a carb issue.

Does sound like a carb issue. SeaFoam might help... Cleaning the carbs of course won't last if your gas tank is full of crud. You might want to check that out too.

prolly air leak. Spray some wd-40 at the boots and see if it changes pitch.

yea, if them boots are not sealing right (meaning lined up and angled correctly) your gonna have problems, including vacuum leaks.

I am earshaved but I'll try.

the boots between the carbs and the heads can be leaking.

Earshave doesn't matter. Actually will make it easier to check. On the boots there is a little nub of rubber that should line up with a little bump on the top of the cylinder intake. Like a little half a pea size.

You can see it in this p[icture at the bottom of the boot. looks like a mistake almost. But that diggle hanging off down there, lines up with s similar bump on the cylinder head.

Performed the WD40 test and nothing happened. Sprayed it around the boots as instructed.

Also performed the blowback procedure. I am unsure if it did anything substantial.

I did notice when i took off the pods that the front carb slide and "mouth" area was soaked in fuel. I've not seen this any of the other times that I looked at or removed the carbs.

I have attached 2 vids that i took after the blowback.

The first video i tried to capture the surging while riding. It was popping and light backfiring pretty badly just prior to the video. I think i captured some of it. As i rode it became less and less prevalent.

The 2nd video i was trying to show what it does at different RPMS and an annoying ticking noise that is on both jugs but more so the rear.

I am planning on doing the ACCT to MCCT conversion and am wondering if I NEED to do it and if the ticking will go away if i do.

i cant tell about the surging issues but i can say that you need to do the acct conversion and it will help us diag the other issues
