I have recently acquired a 1980 CB750C. The P.O. tore apart the carbs, eventually realized he was in over his head and bought a used replacement set and then had someone rebuild them. I have taken them apart for my own inspection and habe come across something I can't find much info on.
The primary main jet and secondary main jet on all 4 carbs are #102. I am aware that when stock they are something like 68 and 102 and can be bumped up for tuning purposes but I have never read about anyone using the same size for both main jets. I have retrieved the original 68 jets and am wondering if I should clean them and put them in or if using 102 for both is a viable approach.
I am thinking the guy that he paid to rebuild them either fucked up and/or didn't know what the fuck he was doing. Any input would be much appreciated. This is my first bike and although I know a fair amount about working on engines and mechanical stuff, carbs are still new to me and everything I can find always has the main jets being different sizes.
Thanks in advance.
