Hello, my china dirt bike wont run on full throttle, everything is stock, carb is clean, and carb needle set to the highest position, air filter is clean, what problem coud it be???
It start to run sluggish and backfiring alotdefine won't run a little better, does it act like its low on power and sluggish? or does it literally just quit running? like flipping a switch
What would help is more information. As in,I could post a video how it runs, would that help with information?
It stutters but dont die, its 250cc loncin engine, i cleaned every hole in the carb and put everything back like it has to be, this is not my first bike but its firts 4stroke and im out off ideas how to fix that stutter at full trotthle, and when i set the needle at highest point it started to run better but still stuttersA video would help quite a bit.
I'm interested in
Model?
Engine Size?
Has it ever run any different?
When you say "won't run" do you mean it stutters (backfire), bogs (loses power but comes back with release of throttle), or dies completely?
Did you clean each jet?
Did you set the needle clip at it's extreme for a reason?
Happy to help when I feel there is something to stab at. -BIG DAN
My bet is we're going to replace the carburetor... They physically break.
Idk, just got it last sundayHow old is it?
