Few YX140 issues
Hi guys,
Was hoping someone could give me some pointers...

- Engine backfires massively when letting off from WOT to nothing
- I set my valve clearance at .1 inlet and .15 outlet, but it's now started tapping. Are these clearances wrong?
- The idle is shocking. Either runs way too high, or stalls. Can't seem to get it right via the screw on the side of the carb!

Any help would be appreciated!

Thanks
Nick

I did reply but it flaming froze.

Service you bike fully, clean carb properly.

.4 tho inlet.
.6 tho exhaust.

The 2 problems about it not running right and probably the same thing to do with idle.

Idle mixture screw needs playing with.
