The reason I am asking this is because I want to buy a new engine for my R1. I've seen some fairly cheap on ebay but want to make sure if I buy one from the US (specifically Indiana) if it will be identical to the functionality of its Canadian counterpart.
I understand California bikes have emissions controls but I'm pretty sure those are external to the engine. All I would be replacing is the main engine block.
So any ideas from you more knowledgeable folk would be greatly appreciated.
