Hello, After going from AKRO TWIN PIPES oops, to metal mule single. The low end power is much better. It gets hot tho, not too much.

What i would like to know is, SURGING !! i know its probably been covered a million times, the bike now seems much worse around town. Lovely once its moving.
Would the Kev mod and O2 controller fix this so its smooooooth ?

cheers
