This video is a rough explanation of how a CV carb works while focusing specifically on the Mikuni BSR36 from a 2006 DRZ400SM. This style of carb is extremely common on motorcycles so the concepts apply to almost all bikes with carburetors. The work was being performed as the bike had been surging and hesitating as the throttle was applied partially, or while cruising at a constant and steady speed. When idling or accelerating hard the bike ran perfectly.
These symptoms often indicate a too lean condition from a poorly adjusted needle.
