I have a California spec bike. Tired of having trouble with hot starts. I'm sure this has been done before, but I have yet to find documentation. Or maybe I have and I just misunderstood what I read. Anyways, excuse my ignorance.


I do not want to get rid of the Ca can. I just want to re route the fumes from the throttle bodies. I saw where a few people routed it to the airbox?? Seems to me this could cause some fueling issues. Does the carbon can emit any fluid or purely just vapors? Or could I just cap the tube to the throttle bodies and run a new hose from the can down and out into the atmosphere? Assuming only vapors will come out of the can.

It is only vapor coming out of the can, and the throttle body only puts the vapor into the front cylinder causing it to become excessively rich when trying to start. Routing to the airbox is fine, as both cylinders will get an equal amount, and it has a chance to mix and dilute with the air in the airbox rather than a strong concentration in the front throttle body.

I've not heard anyone having issues with this setup.

I went belt and suspenders on the issue as it's hot down here in Sun Diego...scroll down for pix.

I routed mine to the airbox and still had some hot start issues, much better but not perfect, so I have now routed it to ground, actually out behind the number plate. No problems at all.
