looking for any info on modifying the 77 cb750k keihin carbs for velocity stacks and 4-4 megs with ... limited ... baffling. I have the carbs apart now, and I'm probably going to pop the main jet from a 110 to a 115, and I was going to shim up the needle by about 2mm, using some close fitting washers. If anyone else has some info on doing this please let me know, I'd hate to be way off and have to tear the carbs apart after building the whole bike!!
