tri650,
I have 140 mains which the operator said was a ba' hair rich at the top, over 6000rpm, not really worth changing to 135. But that's not where I run my bike anyway, the important thing is that the mid range is very strong and that was achieved on Thruxton needles with two shims (each)
A lot of figures you see quoted by folk on here for jets with pods are for Bonnies, T100, Thruxton etc. Our 865 270' motors have a mild inlet cam by comparison, it doesn't get as much gas in there at high revs compared with a 360' inlet cam or even a 790cc 270' cam.
What I've got will be a reasonable starting point for you, but the dyno' is the best place to make sure. The only thing that was changed after my runs was weakening the pilots a bit, the rest was what I'd installed by experiment. I did remove the shims at one stage for experiments sake and the mid range dropped right off, that might save you a bit of time.
