What size is your main jet?

[@zundappies]

90 in the video, because it was new so I drove it a bit too rich but that’s no problem because if you have a new cilinder you need to drive the cilinder in. Now I have main jet 80. Next week i have a membrane on the cilinder so I think that the jet has to be bigger.

Thanks man i appreciate your work, can u send me a link where u bought your set of main jets because the ones i bought have a different thread so they dont fit properly

[@zundappies]
