Mikuni VM30 special jetting

[akremzar]

Hi guys, my project is a ’69 CL350, and I’m looking for some feedback on where to start with Jetting. The cylinder is currently at the machinist being bored to fit my new 1.5mm (65.5mm) oversized pistons from Boretech. He also has my head and is doing a full-on valve and head job, including port/polish the intake and exhaust. He’s an old engine builder so he had quite a bit of experience cleaning the head up and removing unneeded metal. I am sticking with stock cam and valves (for the time being). I have Mikuni VM30’s, and the exhaust is the stock CL headers with Dime City Cycles “12” SS “Shorty” cone mufflers.”

Being that there’s so many variables that have been changed, can anyone offer any guidance or advice as to where to start for selecting jets for the Mikunis?

thanks in advance for any help!
Regards,
Alan

Call Speedmotoco they did my mikunis on my old cb350 after a rebuild and they were dead on after I told him all that was done to engine and exhaust. You can ship them to him and he will jet them.
