mild porting job, 10.5/1 piston, mild cam.
looking into header design but theres very few out there for the ft so looking at building my own.
carb wise i was told to look for a 38mm flat slide. as for jetting hints i have no idea at present so am in the same boat as you.
company that is doing my cam has run them on anything from a stock to a 40mm lectron.
i have been looking at 250 crf/kxf etc carbs but there a bit out of my price range atm. i'll keep looking.

If it is, I can wholeheartedly recommend a Mikuni 38mm roundslide carb. I had one of these on my XR500 I vintage raced, and besides giving a little bit of boost in power, it is a very easy carb to live with. Starts well, idles smooth, takes sudden/quick throttle openings well (you do have to sorta roll the throttle on smoothly & quickly), & is overall easy to tune. I have some jetting specs, if anyone is interested......
Carb: Mikuni 38mm VM Round Slide
Slide Cutaway: 2.5
Needle: 6DP1, clip in the middle notch
Pilot Jet: #35
Needle Jet: Q-0
Main Jet: #220
Air Jet: #2.0
Hope this helps some!!!
Added in Edit: This was the first VM Roundslide carb I've ever had to change that "Air Jet" mentioned on the last line of the jetting specs. It's the little brass one that takes a smallish regular/slotted blade screwdriver to remove from the "belled-out", or air intake, end of the carb. Sits at approximately 6 'oclock or so in that part of the carb, and mostly controls idle/low throttle openings, if I recall......
