all you guys that are having carb issues is because these carbs are alittle touchy, i have nether swapped a nova rossi/os carb to it because i know how they work with tune. the low end on these motors are very responsive on how the motor runs. i dont see the point of swaping carbs you might as well buy a different engine and run it . i am running the new ebmods 5 port and it has the coated crank and wrist pin and slide carb and its nice. carb is alot smoother and all the internals are not wearing as bad .
