Tommy10bikes Posted March 17, 2014 Posted March 17, 2014 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. TTB
Moderator YamaHead Posted March 18, 2014 Moderator Posted March 18, 2014 Had similar issues with my '82 XT550.... Bought a new fuel tap.....cured the problem. Hope your issues are as easily solved.
Moderator Airhead Posted March 18, 2014 Moderator Posted March 18, 2014 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
