Help: OKO 30mm Jetting for 8,000-11,000ft Elevation

[Lindso]

Anyone ever run their blaster this high? I took it that high when it was stock, and it was too rich to idle without my help. I'll be heading up that high again next month but it will be my first time with my current setup (Setup details are in my sig).

On top of that, I can't figure out the OKO carb jetting. Mikuni, pfft cake. Help from any fellow OKO runners appreciated.

In case you were wondering, Silverton, CO is the destination weekend of 07/14 if anyone happens to be in the area


EDIT
I'd like to jet for ~7,000 to be on the safe side, if anyone is near that elevation and has some ideas.

Come on, I know there's gotta be a couple mountain men out there somewhere with an idea! Or even one of you countless mo'fuggas at sea level!

Its the 30mm OKO which is not the flavour of the day.

There are guys here that are struggling to jet the OKO at sea level, I dont like your chances that someone will offer advice about jetting at evevation.

You should grab a handful of smaller jets, half a dozen b8es plugs and be prepared to do a few plug chops when you reach the heights.

You might consider a couple of leaner needles as well.

OKO's are terrible, get it right in one place then utelize one of these two formulae to compentsate for altitude:

I always seem to end up with the bastard products no matter what I'm building. My concurrent project is a Honda Prelude..talk about PITA to find the right parts for.

Anyway, I've have the OKO perfect at a tad rich for where I'm currently at with my light modding, so it's really just a matter of the A/F when I get there. Here at 5500ft I've been using a 148 main, and I think a 46 pilot. I have it taken apart if anyone really wants to know.

But yeah I did go this morning to buy everything..picked up 138main up through 142, and picked up a 38 and 40 pilot along with a few plugs. We'll see though.
