I've just read this interesting thread somewhere on somebody attempting to put a 1000cc engine into a 250cc frame with only minor modifications.
What I'm wondering now is how this beast would be registered. Let's say I've purchased this motorcycle frame and then I stuff a new engine into it and basically just put together my own motorcycle. How do I tell ICBC what sort of bike it is? Will they assume that it's a 250 just because the frame comes from a 250? That would be nice... Paying for a 250's insurance when you've really got +100Hp between your legs. Do I need to bring the bike somewhere so they can inspect it before I get it registered?
Anyways, just sounds like something fun that I might consider if it were possible.
