Long overdue! Took a pair of Mikuni BS38(ID 2F000) carbs apart,cleaned and rebuilt, with all the help of this forum, the carb guide and some vapor blasting attention. Moved up on main jet from stock 135 to 140, stock pilot 27.5(vm22/210) up to 30 (because of pod filters and str8 exhaust) and replaced o rings on stock Z-2 needle jets and mix screws (also set turnouts on mix screws 2 1/4 turns for 1978 or 1979). Set the floats at 24mm. Carb Forum Manual here: http://www.amckayltd.com/carbguide.pdf :thumbsup:

Damn that's a nice piece of work! This is something I've been meaning to do, but to be honest have been rather intimidated. Great set of photos to inspire me forward. Do you have links for the various bits and bobs (o rings etc) you needed to complete the project? Thanks and congrats on a job well done!.
 
Hi, does anyone have a copy of the carb manual - carbguide.pdf or direct me to a new url? Link doesn't work anymore, many thanks...
I know it can b a hassle searching the "tech menu."

Still worth checking out. Under carbs there is a lot of answers to questions with information,(containing the carb guide in the first link), relevant that isn't in the carb guide.
