Enhance Performance with 20-Piece Carburetor Main Jet Kit: PWK Keihin OKO CVK PWM Type Review

Please note they will NOT fit Ruckus/Metropolitan chf50/nps50 nvk003 carburetors as searched. Luckily I have another scooter that suits them.

So far, BOTH pilot injectors I've used have failed IN THE CARB. I just leaned in gently and knowing that carburetors can be easily messed up this isn't my first rodeo. They have a Keihin star on them. Really disappointed. I was able to get one, although I NEVER had a broken pilot jet in the carburettor as a defect; and 2 from a package? Poorly.

The upper main shaft, which has the size marked on it, is actually wider than the original pilot jet that came with the carburetor (KOSO OKO PWK).

I contacted the seller and he sent a free replacement set and nothing had to be returned. Great service, great experience! Installation was relatively painless. When installed, the new pilots looked different. Looks like they're about to get drunk before eating the carbs. After the first one, I poured a little wd40 on the injectors before installation, the rest went fine. Huge…

Being moderately mechanically inclined and familiar with carburetors, this wasn't what I was hoping for, but I've found great use for them and other uses with other carburetors, they are strong, the threads are not, they don't seem to shed, they don't retract and the value is definitely there, a price I couldn't find anywhere else, I've seen a plane cost the same as a package, I received them the next day, my delivery was fast. I am so thankful that Revain makes this possible. I used to spend…
