help my mechanic

[chicago1010]

I just spoke to the mechanic that worked on my bike recently.
I've been having sputtering and some backfiring.
Iknow it needs to be rejetted, which he did, however, he didn't adjust them right.

My question is this, he told me that there are individual air filters has he took the airbox off and he said something like they were 3 stage, whatever that means.
Does anyone know what he should set them at.
Much thanks

Mike

So YOU have the magic wand. I wondered where it went....

So, what'd he do?

www.dynojet.com has a little explanation on "stages." Click on jets.

He had installed 152.5 jets and he rejetted to 147.5. It's running real good at the moment. Now that he showed me how it's done I could easily do it. I keep learning alot from this forum and from him.
thanks for all the help, not just to my post but all others.
