OK guys, get out your voodoo dolls. I have looked at the jetting of 3 different factory sets of 44PHH Solex carbs for the 2000 and this is what I found:

Early carbs
37mm chokes and jets are 250 "A" blocks and 60

Early carbs
34mm chokes and jets are 250 "A" blocks and 52.5

Late carbs (external float adjustment)
34mm chokes and jets are 140 "8" blocks and 55

My question is which jetting should work best on a B cam stock exhaust 2000? I can see the difference in jets between the early sets, but the late one has me baffled. That is a huge change in the jetting...

When I went to Shasta, the best Solex tuner in Japan set mine up. I have the new style. I will look and see what I have and post the results.

That would be...YOU, of course.

(edit: the post this was a reply to has disappeared, so this probably won't make much sense to anyone who didn't see the post that alluded to a "guest" who had his Solexes tuned by the best tuner in the world.)

Are you looking for the type 1 (old style) or the type 4 (new)? The jetting is different between the two.

Good question. I have both the old style and the new style, so both answers would be appreciated.
