Just beware regarding the old tax disc. A few people have been done by the bobbies for displaying an out of date disc. Even though we are electronic now.

CB750 / Carb main jet settings CB750 K1

1972 CB750 K1 with HM241 pipes. Currently running with 110 mains and 40 pilots but it is bogging down on 1/2 to 3/4 throttle.
Never did this before the top end rebuild I have recently completed.
When I restored the bike back in 2003 I had to change jets to 110 to make it run OK so why the change now?
Any comments from the experts out there?

OK
Engine top end rebuild clean carbs, new plugs, carbs balanced, timing spot on but have a misfire. Bogs down over half throttle and pops on overrun as if the exhaust is leaking.
The only thing I can find is that the rubber bellmouths are not a great fit into the air filter casing as they have shrunk with age.
Any of the experts out there with any clues?

its the one for a K1 if it is a genuine one. Want to sell it if it has the push pull throttle cable?
