My friend has a zip ac with mhr cylinder kit,motoforce full circle crank,pwk 21 mm carb i said eiva mhr team or c21 but what do u think?
i think you should use that magic search button, or just look up on this page. from the barrel and pipe guide by swift
from the same damn giude, literraly 2 secs down the page, opens your eyes and dont be so lazy man 5 suitable pipes, pick just one thats wat i think
Different kettle of fish when it comes to air cooled... The C16 actually matches up better to an un-tuned air cooled MHR cylinder kit than their normal high end race exhausts. You should only be pushing for a C20/C21 if the MHR kit has had some serious work. Also not sure why someone would cheap out on the crank and why you would run a shit 21 when it should be a 25mm. arc:
