Carburetor Jet Kit

I needed a 42 pilot jet and this kit came with one. There's smaller kits out there that had the 42, but for barely more money, I got this kit which has all the main and pilot jets I could ever imagine needing... plenty of spares now to give to friends if they need.They are marked with the Keihin 'K', but I doubt these are real Keihin. Having said that, they fit right up and the bike runs fine. I have no way to 'measure' if the printed size matches the expected flow-rate. So, is a 42-pilot in this kit -the same as- a real Keihin 42-pilot? No idea. I tune the bike to run with the jets I have, so I am using this 42 pilot, and got the bike to idle and behave at low throttle. At the end of the day, that's all I'm looking for... make the bike run.

Nice variety

Works perfectly for nibi carburetors

Works good

Perfect for my dirt bike, 2020 xb88 250cc with a PZ30 carb W/accelerator pump.

Pilot jets have all the same size holes on the sides, only the center diameter changes, main jets seem fine. Waste of money really.

Not knowing where some of these numbers or sizes go sucks....inlet air mix?....pilot or main...doesn't look the same

My husband was able to fix our son's quad himself. It is a huge help and of course cheaper to buy parts on Amazon. All parts were in the package.
