Took a pair of Mikuni BS38 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 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). Plenty of pics.
