Mikuni vs the world

[nastyjones]

I asked the dealer for generic 135 large head main jets & they sent me small head 135 Mikunis. I know they're not the same size but am unable to find that conversion chart that was posted here earlier. Any help is appreciated. Couldn't find it using search.

Hope this helps...

nasty, I don't think it matters what the head size is. A 135 main is the same large or small head. Correct me if I'm wrong.

Sorry, I can see that my post is misleading. What I meant was a generic 135 jet is different from a Mikuni 135 jet, IIRC.

True?

There might be some small manufacturing differences between O.E. Mikuni and the more popular K&L 'generic' jet's, but I think you would have to flow test them to know if there is any difference or find someone who already has. BUT, will it matter that much for the minute differences between the two brands until someone actually runs the engine to see what it really needs?

It may be just splitting hair's...

Jeff at Z1 might know for sure. P.M. him and ask.

It is dynojet jets that have a the difference from OEM jets.

Got it. Thanks everyone.
