Main Jet and Pilot Slow Jet Kit for Mikuni Carburetors Large Hex VM4/042 & VM22/210 Set 30 Pcs

Vs my stock makuni jets: the pilot jets are a different design ( they are metered more by a ventury effect with the entrance of the jet being considerably smaller than any of my makuni pilot jets, but are larger on the exit towards the carburetor)(they do work and i was able to dial in my pilot circuit despite my skepticism about the design.) (The main jets are similar to the makuni main jets although possibly a better design, atleast visually. These jets have a counter sink leading to the orfice, where the makuni main jets do not.) Details aside, while I can't really say if they are true to their number or not, I was able to go up and down in jet sizes to change my mixture, so I would say they are worth buying base in the price.

these are actually good, however if you bought cheap knock off carbs{carbmann} the mains WILL NOT FIT thread pitch is meant for GENUINE mikuni carbs
