Title: Mikuni 40/4mm
Post by: subarumy98 on October 01, 2009, 02:01:29 am

HI All

Might have to replace the current 40mm Mikuni on the 500XC - any benefit to going to a 44mm now /
Apart from sucking in small rodents and little kids of course ?

Gidday Subie - I understand the 44 was a difficult carb to tune (velocities lower due to larger bore) and the 40 made the 500 run much better.
