Hi Lads,
Just removed a Mikuni VM off my Jawa 350(Model 634)as the previous owner had it fitted.
I was getting 42mpg.
I fitted the standard Jikov Carb as I have always done and I am now getting 53mpg with no difference in power or top speed.
Just thought I would point this out as this was my experience with the Mikuni.
Regards,
Ger
