Guys

Just courious , what would happen if you swopped your VM26 Mikuni for a slightly bigger VM28 Mikuni carb ?

Cheers

Greg

Reason for question I can buy a 28 for a lot cheaper than a 26 ... and then jet to suit !

    A 28 will lower the air flow velocity, which will probably have a negative effect at low rpm (exactly where you likely run your motor most often). You will be able to flow more of the air/fuel mixture, but only if the porting is designed to handle it.
