Rear coupler to the rear #2 crank throw

I miked mine and it’s 4 thousand of an inch off. Can I still reuse it? Will it just blow up on me? Or am I safe?

Who was the crazy out on their Jetski around jordon bridge, Ontario in Lake Ontario on Saturday? lol

Is it just the tuning factor that everyone says to stay away from dual carbs?

I’m thinking about running double SNB46’s, would this still work?

Is that for a single SNB 46?
