17 Beta 4T carb spitting fuel hard to start

Featured Replies

Hi

i got 17 evo 4T factory and every time my bike die on little hill it always spits fuel from carb on ground.Also it's very hard to start when hot afterwards.

should I adjust the float bowl or do the billy mod?

jetting is 130 main and 25 pilot

fuel screw out 1.5

thanks

The mod is because the carb on the two stroke has a bit of a downdraught and is sensitive to float level.  That on your bike is more or less horizontal so should not be a problem (though any carb has to be correctly set).

There is a hot start mechanism but I am not familiar with it - the manual can be downloaded.

Fuel screw setting sounds wrong to me.

2.5 to 4.5 turns out I have used.

All ways use the red hot start button when the bike is warm. Even then if i kick it twice and it does not fire, i will have to hold the throttle wide open as well as the red button on as i kick it.

Yeah that is good news. I hardly ever need to use the hot start knob.
