Question Questions concerning Modification

My 2006 599 is originally a California model.
The Evaporative Emission Canister was removed by the previous owner.
I now have four hoses hanging from the bottom of the bike.
Do these hoses need to be plugged or filtered?

Also I just put a slightly de-baffled stock muffler on the bike, original was too quiet.
The stock muffler had a catalytic converter inline with it.
The new muffler does not have one.
I am assuming these two changes will make a difference in the back pressure, and am wondering if this means I need to change the carb jetting.
Am I okay, or do I need to have the carbs re-jetted.

I don't have any hands on knowledge about the 599, but assuming it is more or less the same as a 919:
  1. plug any of the lines that are vacuum
  2. The bike is fuel injected. While you may want to play with the mixture with a power commander, it isn't required.

I would plug the lines, or follow them up, remove the lines and cap the ports they are connected to. (Edit: And I would be argued with by 50% of owners according to the post I found below.)

As far as the carburetor, that's going to depend a lot on the exhaust, elevation, and how the carbs are currently jetted. So.... maybe?

All US market 599's are carbureted, both 2004 and 2006 models. Just removing the smog equipment will not necessitate a rejetting of the carb. I even installed an aftermarket exhaust on my 04 and it ran fine with the stock jetting, they're set rather rich from the factory anyway.

Some of those hoses are carb overflow tubes I bet, I would NOT plug those .

Crankcase breather hose perhaps? Trace them back, find out where they go before plugging anything.
