Re: SCRAMBLER 50 CHEAP MODS

Simple. (Caveat -- some people will tell you that drilling your jet is not accurate and that it will cause problems. I say BS. If the engine runs properly with the selected hole size, there are no problems. Besides, Mikuni does not supply jets for the VM17. HINT -- Holley main jets fit!!)

Take the carb off the engine. Remove the float bowl. Remove the main jet. Drill it using a 60-80 number drill set. Depending on the mods, I would start with a .032" drill, raise the needle one notch and see if the engine accepts full throttle. If it does not, go one size bigger until full throttle is achieved. Next check the spark plug to confirm jetting.
