will this work?

IIRC a VM26 is what a blaster comes stock with, that one should work for you, but you'll need different jets, those jets are going to be way too small. stock blaster jetting is 230 main and 32.5 pilot.


for that kind of money, i would probably go with a keihin 28pwk. it's a little better carb IMO and it'll give you more room to grow
 
VM26SS/ Mikuni/1, is what a stock Blaster comes with.

The main jet, pilot jet, air jet, needle jet and jet needle are not suitable for a stock Blaster.

You will have to swap out all jets and valves to get it to work.

Look around for a 28mm and feel the difference.
