bike start after a long while then cut out
Permalink  
 


trying to get a project up and running  new spark plug cleaned all carb and jets air mixture screw 2 and bit turns out.

bike starts and runs for around 30 - 40 seconds then cuts out seems to run better with choke out (bit of back firing also)

 

ANYONE ANY IDEAS?? many thanks!

If you undo the float drain screw do you get a constant flow of fuel out? 

If so, it sounds like the common problem of a slightly blocked pilot jet.

Some tips here

Maybe you didn't clean the pilot jet quite enough, soak it in some solvent for a good long time and blow through with compressed air if you can, or you could just replace it, they don't cost too much
