Lynn,

Talking to David McC on carbies. I believe you advised him that 2x 42mm Mikuni's are sufficient for a 13B to 300 hp.

I'm working on the single and for the demonstrator I will stick to Carby, I'm looking at going for a 44mm inlet and am hoping for at least 125hp at a max RPM of 7,500, if I can get it at 7,200 all the better.

 

If I go for a 44mm tube what size Mikuni should be sufficient?

 

The tube I have is 41mm or 44mm, should I go for the 41mm ID for increased velocity and a 42mm carby or a 45mm carby?
