Dunno, because I am running filters with 135 main jets but am having serious fueling issues was gonna try 140 next in mine. How is your bike running?

dont know i bought it as a non runner

the guy i bought it from assures me it ran fine before he parked it up in his shed 8 years ago, so ive stripped the carbs and found this size of jet.

I've got a set in the cave all set-up with K&N's,air correctors etc, so I'll have a look tomoz and see what jet's are in there. Have to say 147.5 sounds a bit big.
