2002 zx6r boggs down when trying to take off.

I have an issue with my 2002 zx6r, the problem is as follows, I am at a light with the bike idling perfectly, and as long as I keep the clutch engaged I can rev it, but when I go to take off the bike rpm's increase a little bit until the bike boggs down and in order to keep it running I must keep the throttle wide open. The bike then will run at 1500 rpm (max) and if I let off even a little bit the bike will quit.

I am able to restart the bike, to the same state it was in where I need to keep the throttle maxed out and it sounds as though 1 or more cylinders are not firing. The bike as 20,000 km on it and I have since cleaned and synced the carbs, changed the oil and replaced the fuel filter. I have read some similar problems where a throttle position sensor (tps) was suggested, or a rectifier/voltage regulator, but I was looking to see if there was a consensus for my specific problem.

Any information is appreciated,

I had simmilar issue... but need a bit more info.

But first thought is you running on 2 or 3 cylinders. Feels like there is no power even though bike seems to idle "fine"..?

Do you have rough idle? What happens if you blip the throttle in neutral, does it stumble and then return to idle?

I thought I was dropping a cylinder as well, I checked fire to all cylinders and changed plugs as well as the fuel filter, but I may be missing something else.

The problem doesn't arise at all until I put load on the bike, even if I cycle through gears and put it in neutral at a stop, I can still rev the bike and it seems as though it is running fine.

Also something that might be notable is that this problem doesn't happen all the time and I have incredible trouble getting the issue to re-occur when I want it to. But it always seems to happen in the worst times possible. Even after this issue happens I can sit on the side of the road with the throttle maxed and the bike will begin to run properly again and I can drive.

Anything else that you need to know?

See if the fuel pump is working well- see the repair manual or previous posts.

Add both SeaFoam and StarTron to the fuel tank, to see if this helps.
