49 State 919 and California 919 Comparo

Besides the Evap canister and gas tank on the California 919, any other differences? Do all California 919s say "California" on the VIN plate?

I'm trying to figure whether or not my buddy's 919 is from out of state. There was no Evap Can, which could've been removed. I don't the know obvious differences between the tanks.

Pre 06 CA models had a cat & stainless Y. The pre 06 49 state did not. The cat equipped models also have a different ECU as far as I know. 06 & later all have a cat & stainless Y but I believe the CA models still have tougher emmisions to mett through the ECU.

They're also narrower so they can split-lanes easier on the freeway!


Just kidding...

On the 04-07 Yamaha YZR-R1 I was able to hollow out the cat. with a big screwdriver. Do you think this would be posible on the 919?

Slightly different throttle bodies with more vacuum ports & extra vacuum lines associated with the canister too.

Are you sure you want to get rid of the cat?

I have an 07 cbr600rr with a cat. It's the cleanest motorcycle exhaust I have ever seen. No soot, no smell, no nothing. I love it. I wouldn't dream of changing it. Yeah, I could change the exhaust and put a PC on it and get another 5 HP. It runs perfectly as is. I'd rather not have the smell.

Honda does cat converters better than anyone. I'd leave it in.

My 919 never came with a cat in 02. Cat-equipped bikes have a matching ECM (which I dont have) so no point to leave it in on my bike when changing to a stainless Y.
