Actual jet size

[Tim kapopoulos]

I was wondering if anyone could tell me if the orifice sizes of a genuine kehin jet and the knock off kehin style jet do they have the same orifice? Basically If a a real kehin 110 is the same as the ones that would be in the 21 pwk carb on the drr stock. I found a lengthy jet comparison chart that gives you orifice and jet sizes between kehin - dynojet- mikuni just not sure .. Without measuring ....... If that makes any sense?

I always pitch the generic jets in the trash can, I've seen weird chit on the dyno with the knock off jets :ermm:

That chart you found is very good for those comparisons.some knock offs use the same jets as dynojet just stamp a different name on em. But for the most part what the problem with any other no name company is their quality assurance. 2 jets of the same size aren't exactly the same size. And especially if your using 2 different companies cause you needed more jets.
