Hiya Captain ere.Got an xt with an overheating problem.when i stripped dow the carb i took out the mixture screw(pilot screw #35 on page 280 xt250 1984 clymer manual)and didnt count how many turns!! I have since had it re-bored to 4th size over.checked oil(flow/type)inlet manifold,and air filter,but I feel the problem may be with aforementioned pilot/mixture screw,any ideas.Pleaseeee!!
