I have both the original and a scorpion can for my nc21, but the bike seems to rev better with the original. Would a rolling road tune sort it out for the scorpion can, or is it something I can do at home?
Would the scorpion can liberate a few bhp if the setup is correct?
The scorpion can sounds evil, if I go past a cop I do it on part throttle and in a tall gear, and they still look over...
I suspect I'll get pulled eventually...

Thanks,
Matt.
