I bought from Jets R Us, after searching this board.
Got back jets that dont fit.
After further searching, found this below from LM.
The JRU jets do in fact have the line around the head.
Where can I find the right ones? I need at least a 145, and would prefer 150

The main jets threads for these type carbs were all the same.
HONDA did use a different thread and holder with a later carb and they look the same but are not.
The newer jet will have a thin line machined into the outer edge. ............lm

Hi
Anyone know if there were different threads used for the CB72 ( and I guess CB77 ) main jets ?
I seem to have in my box of carb bits, main jets that are different threads and one main jet holder
that looks different from the others.
I measure them as M5 with either 1.0 or 0.8 pitch so either Keihin changed them at some time
or I've got bits from something else.
Any info gratefully received.
thanks

Note - reason for looking is I want to turn down some Amal jets to make a choice of > #100
main jets since its still weak at the top end n std #100s. I have a chart giving relative IDs for
Keihin, Amal & Mikuni and can't find anyone who has ( for example ) 105 & 110 jets in stock
but have lots of old Amal stuff.
