I people I have my bike that as soon as I slow down on the road for a light it stops. I start it right away no problem but have to keep a little bit of gas so it does not stop, in idle it runs not too good, I played with my rpm but when I adjusted it it runs in the 2000 rpm and does not go down.. I therefore cleaned my carbs, balanced all four carbs played with the mixing screw and still it does not work. When it's hot I let go the gas and it stops.

Anyone have more suggestion please for my problem?

 

Although unlikely, have you checked your timing to see if it's off? Otherwise, spray some ether (aka: starting fluid) around the carburettor boots and lines to see if the idle changes. If it does that would be a sign of a vacuum leak. One other thing to check is the float levels of your carburettor fuel bowls. make sure they are correct.

 

Yeh continue with the basics. Check for vacuum leaks as mentioned and float level. But I have not had a level issue cause an issue when hot only though. Have you ran the choke up abit to check if it still runs when hot?
