i have some dynojet 90 mains, what would that be in mikuni approx?

Multiply by .937 and it will give you a CLOSE Mikuni number... Or is it divide the DJ by point 937 to get the MIC equivellent...Oh crud...BILLLLLL!!!

That's pretty close to a Mikuni 85.

Dynojet numbers tend to be larger than Mikuni numbers.

.9375

90 x .9375=84.375

85 it is Steve!

Oh yeah....Like I said, im tired...

BTW, Steve, it appears that I will be helping Dogma rebuild the top end on HIS 850...You care if I borrow your fancy valve spring compressor?? I still havent made myself one yet, and I refuse to pay the 200 plus or whatever Z1 and others are asking for one..

You keep referring to this "some guy" and his website.

I guess we're gonna have to pressure him into becoming an active participant on the board.

so why would a dyno jet kit have smaller than stock jets in it? My jets are according to suzuki i think 105 and 95 and according to the actual mukini numbers 97.5 and 90.

The Dynojet kits have different jet needles and sometimes tap in a main air jet correcter. They also drill the slides.
All this changes the picture a bit.
I've never installed a Stage 1 kit so I've also wondered why the jets are smaller than stock.
