OK I have a 2001 blaster this thing is unique to say the least.. just had engine rebuilt from top too bottom including new head weisco piston 68mm a vitos crank...It has a fmf fatty pipe and silencer flat track set up..... Now the question!! I like mikuni the best out of carb selection what size should I go with for that size bore??? I want the most power possible out of it but want it to last longer then a few hard run so and educated opinion would be great...
