Beta Evo 80 Carb Jets

Recommended Posts

Hi,

We have a 2010 Beta Evo 80 Big Wheel, which needs the pilot jet cleaning regular as it seems to block quite easily.

It is a #38 and i was wanting to know if this is the right size ?

The bike can also momentarily cut when on half throttle and it catches the lad out when

on a climb, is this connected to the pilot jet size ?

Any suggestions are welcome ?

Thanks.

38 jet or much smaller should not block

Sounds like you have dirt or water in your fuel, thorough clean out of tank, fuel lines and carb needed, perhaps the in tank filter is faulty.

38 is the correct pilot jet,we had the same problem with the engine cutting out,it was caused by low float height,we set it to 16mm

and the problem went away.basically it was continually running the carb dry !!

the float height should be 16mm measured from the gasket face to the furthest part of the plastic floats

make sure both sides are the same,adjust by bending the central tab - be gentle !!!!
