Hey folks, has anyone ported, or port matched an A55 yet, and where are it’s factory faults. I haven’t torn my new bike down yet, needs to break in a little, but after that I’m going to clean up the ports if I can . I’m kind of excited to see what I can to do the ports. The last 400cc quad I ported pulled off 7mph more just cleaning up the transfer ports down were it matches the case, that was a surprising improvement, and not expected.
I’m not going to mess with the port height and timing , or the port width,just clean them up of anything to look like an air flow obstruction. Anyone had any luck yet? Thanks
