Must have for people with lots of carburetors
Useful kit to have many different jet sizes on hand to precisely dial in and tune your carburetor

Had the pilot jet size I needed
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.

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

Good product
Jet kit was as described and worked well after installation. No issues with performance or compatibility. Only observation is sizes are Lazer etched into each jet but oem is punched. I don't know if time will wear out the etching or not but other than that good product.

Decent little kit
Not a bad kit for the price but they didnโt have mikuni pilot jets in there (the smaller ones) so for that Iโd have to give it 3 stars but if your keys are the bigger ones then Iโd suggest buying !
