when you have the air box off stick 2 fingers, one in the carb on clutch side and the other in the middle. tap the throttle and see if the slides move the same, then stick one finger in the middle carb and the other finger in the carb on the mag side and do the same. also grab each choke cable and move it up and down to see if its lose. If all 3 are lose good. When you have the carbs apart make sure all the jets are the same size. Like the main jet make sure there all the same. on my 95 xcr its 260 main jet(and yes its a triple) If youve done all you can do with settin you carbs up and adjusting it right then it could be your clutches and youll have to rebuild em both. Thats what i did with mine. Rebuild em both. Bushing, helix buttons, rollers, cam arm. whole 9 yards. Hope you get everythin goin right before snow hits
