I calculated the diameter and length of the runners by measuring what would fit in the chassis. Very scientific.

I'm still trying to get them synched. I have two motorcycle synch tools that measure vacuum at each carb from the port at the top of the carb. It's not easy and I am going to have to do some tweaking, but it idles fair and revs like a banshee! Just fiddling around, it easily revs very quickly to 6500 with no load, in neutral.

Bike EFI with MS controller would be nice!
