 Re: gas pouring out of mikuni
I had the same problem. I put a fuel pressure regulator from the same aisle right after the pump set to 4 psi and it works great. I also like that if I get in a bind and have to replace it, it doesn't matter what psi the pump is.

 Re: gas pouring out of mikuni

 Re: gas pouring out of mikuni
You need to bend your float tab and that'll stop the gas from pouring out, Known in the Mikuni's

 Re: gas pouring out of mikuni
Its nothing bad its normal on the mukuni's some do it some don't i had to do mine, it just allows the float to put more pressure on the seat and seal it off and not keep letting fuel pour in the bowl.
