Default What size Main jet ?

Hi guys, my saga of getting my fuel and air to mix in a productive way continues.
I was wondering what size jets are you guys running ? and with what filter/exsaust combo ?
It just seams logical to ask rather than starting from square 1 my self.

Also I've been reading about 'open top' BMC race filters, any body got any experiance with them ?

Thanks,

Me: Micron system, chopped down can, BMC race RS filter (open top one), tank raisers, defoamed tank. 160 mains (mikuni sizing), drilled slide holes AFAIK

Cool, that's the way I'm heading. I've got a cut down scorpion can (down to 8", 104 decibels @ scrutaneering) Or a micron race can, standard lengh.
A BMC road filter with the top cut out, driled slide holes and mystery jets that were in the bike when i got it. It's runnign a little lean.
I'm looking for 160 mains on the net now, I can't find anything larger than 152.5, which I've ordered. Where are your's from ?
Does your sv ride nice ?

cheers, Boo

Mines a little bit rich, but that's the choke plungers, was alright before.

I would guess 160 is too big on standard system, the micron doesn't flow too well, but still an improvement over standard.
