Anyone using a 36mm and a rad valve in liquid R?

[250RNUT]

I just aquired a Boyesen rad valve for use in my 86 250r.the carb I an going to use is a 36mm Keihin. Just wondering if anyone else has this combo because I need some jetting info from you as to what jet sizes you are running. Any help would be appreciated.

What other mods do you have done? I am about to put my 86R back together thats been freshly ported by esr, and an esr pipe and silencer. I am using a rad valve with the same carb. Are you using the pj or pwk? Mine is an old pj that has been done up by duncan racing. I am interested in anyones input.

No mods just a rad valve and fmf pipe and silencer. Stock .040 motor.I am going to be using a 36mm PJ that has not been done up at all, but I have NO clue where to start the jetting as far as sizes

[Dammit!]

When in doubt, go big. Better to be way too rich and slowly lean it out than the other way around.

I'm running the rad valve with a 38mm PWK, FMF Fatty and powercore silencer, mx ported top end and Uni clamp on. Currently running a 175 main and a 50 pilot. This is at 1100ft above sea level in a very dry climate. I would GUESS (let me re-emphasize GUESS!) you'll end up with about a 165-168 in there for the main. Especially if you're running an aftermarket filter with no lid. The difference in climate could throw my guess way off though.

If you hook it up and it appears to run just fine, DON'T TRUST IT! Do plug chops immediately no matter what. A lean running motor will very often appear to be running great. Right up until it burns a hole through the piston.

Thanks for the info Dammit(thats funny) It gives me a good place to start from.

I don't have the RAD valve but I've got the 36PJ along with FMF pipe and silencer and K&N. I run the following jetting:

DGJ needle 2nd groove from top/summer -- 3rd groove winter
6.0 slide
62 pilot
170main-summer/175-winter

I'm at about 500' elevation.

The jet needle I have only has 2 letters.Yours shows DGJ where mine only shows GH.My slide is a 6.0 though which is common up to 36mm
