Carburetor Fuel Screw For Beta Rev4

Featured Replies

Hy DennisGr,

I have the fuel screw on my beta rev 4, it's the easiest thing to regulate the carburetor, absolutely perfect.

But I think, your scorpa has not the same carburetor as the beta...!?

I am sure it isn't have the same carburetor but they are both Mikuni and it might have the same thread and the same tip on the fuels screw so that I could use it after modifying. If you follow the link there are pictures of the Scorpa 125 original and a CMX fuel screw next to a ruler with millimeter scale. I modified the CMX fuel screw to fit. The thread M6x0.5 was right but the tip was too different so the adjustments range was not right. So what I wonder now is if the Beta Rev4 fuel screw is a better candidate for modifying or not. From the not so good pictures I have seen of it it seems too short so would have to lengthen the stem. Just as long as the thread and tip is right it should be doable.
