just got new carbs-need a starting point

[harbinger of death]

First of all, merry christmas to everyone. My problem is that I got new pwk 28's and I dont know where to begin with jetting and the rivers are almost ready to ride. Here are my mods-t-6's, +4timing, pro-design foam filter-no lid, and v-3's. Elevation is around 500 ft. and temp is between 0 and 30. Thanks for any help you can give.

can anyone help me? I've never run keihins before. Is there a general rule of thumb for going up and down on mains to adjust for temp? I just want a starting point.

there was a thread in there of something like list your mods and jetting like 5 pages long

52 pilot 155 main is safe but stock port dont be suprised if you end up going down into the low 140s

I have PC's k and n open airbox sea level 30-50 and kevin from hjr told me to run 148 / 48 to start. Havent got around to putting them on yet but Ill let ya no when I do

Thanks for your help guys. Looks like I'll have to get jets ranging from 140 to 170 to cover the weather here in wisconsin. I try not to ride much when it's below 0 or when it's over 90 so hopefully those will be enough jets. How many main sizes do you usually change before you have to change the pilots? Looks like I have some experimenting to do to get her dialed in. Once again, thanks for your help.

I'm working with the same thing. I just got some pwk 28's as well a couple weeks ago. I threw in some 190 mains (only set I had) and 52 pilots and it ran fine but was far from perfect. I ended up busting an idle screw right away and just threw in the towel til I get more jets in the mail. Be careful with those things. They break so easy. I happened to have a couple extra but I will be getting some steel screws in the future. I didn't even bother to look at my plugs so I have no idea if or how rich I was running. Do you trail ride in the winter? I head across the border to ride in the summer but have always wanted to ride in the winter over there. The trails are so nice!
