Yes pressure regulator or no if you buy the right fuel pump instead. 57, 145, 170, F6 for a start. 145/170 might be a bit lean, you do need a rolling road session or at least to experiment a bit. It's a black art!
I'm having a but of a stress with these carbs - has anyone fitted the CB performance kit before? I know this may sound stupid, but I can't work out which way round these carbs should go! Has anyone got a pic of these installed, as I can't find anything on the net!
No problem now - worked it out in the end! Lovely looking kit, and just feels so much better than the Marmitee EMPI kit - I'd recommend this kit to anyone!
