84 250r Carb Question

[ziggyscheller]

I am wanting to buy a new Mikuni carb, i am want to jump from the stock 30mm to a 34mm. But my question is, what is everyone else doing on the intake/exhaust boots since the 34mm carb has a different diameter than the 30mm on both intake/exhaust sides?

why would you switch to a mikuni? i went from the stock 30mm keihin to the 34mm off an 85r with no mods required. some people boil the boot but i didn't find a need to. hope this helps

Like bradshea said, either boil it in water to loosen it up and stretch it out or use a hair dryer like i do!! If you do stretch it out put like a beer bottle in the boot and throw it in the freezer to permanatly stretch it..
