Works great on nibbi!

as described

There's 2 lenghts available so measure your original before ordering. Quality looks good and there's plenty of options from Ritch to lean. They look the same, but if you take time to measure each one is different. Have fun tuning! Oh and the extra clips are nice too.

These are 100% made for 26mm to 30mm carburetor, if you are having trouble getting to full throttle with a bog than get this kit, mostly Change the needles

Good

I bought 4 sets of these. Although the numbering doesn't line up with actual Keihin numbering, they are consistent with each other and work well in a 4 carb setup. Having lots of [cheap] choice when adjusting has been a great experience.

Good jets. They go from smaller to larger like you would expect. Not sure if they are exactly drilled, but jetting a carburetor is mostly about using the jet that works in your setup. It's not an exact science. These work very well for the money.

The #35 jet in my set was mismarked or was faulty because it was extremely rich compared to the #38. ATV idled great at sea level with #38 so I changed to #35 for higher altitude. Suddenly it was flooding out and wouldn't idle. Pulled the carb thinking it was stuck float or needle and seat but nothing. Put it back together and same thing. In desperation I ordered a new carb (not a cheapy either) and installed the #35 jet in the new carb and had the SAME problem! Installed the #38 and it idles perfectly....compared them and to the naked eye I could see a larger hole in the 35. These are tiny holes so being able to see it means it was waaay off. Cost me a new carb for no reason. Really poor quality control.

Bien

As advertised

The needles appear to be what they say they are
