Heres a PDF of the manual, or a manual for the PHH series.

Mikuni has website with a lot of info as well:
http://www.mikunipower.com/PHH01.htm
Even has jet recommendations for a 12A. Image is bit large. This is page
29 of the manual. They have scanned in the 30 page manual with links
to each page on here.

Yeah I think his venturies are probably spot on for a 13B but the jetting is off. I gotta
believe the 13B needs more gas than the 12A According to Mikuni a 12a uses the
39 venturi and he has a 41 which should be fine for a 13B.
Kory, just remember to tune in the right order. Idle, progression, cuise and then
WOT. Each builds on the other. By progression I mean the transition from idle to
cruise.
Get that idle mixture setup right and at a reasonable rpm. Then
work out any transition issues going from idle to cruise. Usually involves adjusting
AP, pressure and/or floats. Then take it on the road to get loaded and WOT tuning
done. I'd do it on a large empty lot or road where you can pull off randomly to
tweak things. Engine sound, exhaust smell and plug color are the old school ways
to tune a carb. If you have access to a wideband that would be ideal I guess.

good advise! the great thing about the carb is that the old school way does actually work great. i have a WB and used it on the P port, but really only to check my work.
i also kept a little notebook, and went thru each part of the carb one at a time, IE i tried all my idle jets first, then the main fuel jets, etc etc. so i can go back and look at my notes and i can tell you what each part did. once you know what each part does, then you know what part to change.
