Progress on the 750
Johnny4428:
Thanks K2-K6 for the info regarding oil circulation on the 750 and fuel situation with the 550. I have done a fair bit of fettling with the Pd46a carbs on the 550. I have had the carbs off three times, maybe I made a mistake by not replacing the slow jets, but I did give them a good clean. Now I have adjusted the screws both ways in and out but ended back to 1.5 turns which is the base mark for these carbs on this bike having not made any improvement on the starting. Also to take the bike above 60mph and 4000rpm works better opening the choke with throttle opened, hence my theory for needing more fuel. Maybe I should replace slow jets yet? I know these carbs are tricky but a bit of a challenge too as far as I’m concerned. Not going to do anything with the 550 for a couple of months until 750 is finished and road ready.

This is the state of play now. Just ordered Dot5 silicone based brake fluid (won’t strip paint), fork oil to put in also and still deliberating over number plate design. (Pressed aluminium black and silver probably)
