Hi I have a 2002 bws 50 w/ a 70cc BBK yasuni z exhaust, foam filter. When I get to 50kmh it sputters and if you hold it long enough sometimes it clears up and hits top speed. Also it only does it when it’s warm. Anyone have any ideas?
Thanks.

If it also backfires you may be going lean. Check for air leaks if none try to upjet or move the needle clip down (if applicable )

The backfires aren’t too loud but sometimes it does pop a little louder than usual
