Had the same problem on my mates 2KF xt600 , same carbs but it was getting a restricted fuel supply into the carb.

Check the fuel tap

Supply pipe

Worth also checking the elbow join going into the carb just to make sure theres no restriction there.

Other than than also check the small feed pipe linking the second stage carb.

Had similar issues with my '82 XT550....

Bought a new fuel tap.....cured the problem.

Hope your issues are as easily solved. :eusa_think:

There may be a fuel filter screen in the carb float valve seat, there may also be a filter screen inside of the fuel tank...check these are clean

Hey Yamahead It's nice to see you back on the forum

The one in the float valve seat was the one we found that was clogged on my mates, at first i thought it was a fag butt.
