Title: CB750K7/8 PD carb accelerator jets
Post by: martin_uk on March 31, 2021, 08:57:49 AM

I am having a problem cleaning passages without removing the plugs fitted to drilling for accelerator pump jets

I have read about removing the small plugs with pliers, but on mine they are flush with surface so nothing to grip and not sure about putting pressure on jet to try to push down and force plug out.

I have considered drilling out, but then would need to get some made up, unless they are available?.

I have also considered drilling out then tapping hole so that a screw with seal could be fitted, apart from the entry one on carb 2 with pump.

Has anyone found an easy solution?

Are new jets available?

Thanks guys

I managed to clear obstruction without removing by using carb cleaner and compressed air.

Changed main jets  to 110 from 125 and one 0.4mm washer under needle clip.

Now runs fine  :)
