I just got done with a few mods on my carbie Scrambler. One of the things I did was strip off the smog bits. I wasn't sure what to do with one hose, should it vent to air or should I cap it?

Here's the hose, with a very crude red arrow pointing to it. The hose attaches to a hard pipe between the carbs at the upper part of the carb body towards the engine.

Read Gary's Evaporative Loss system removal instructions. He has you buy a longer hose and route it down and vent it alongside the tank breather hose.

In sum, it must be vented.

Wow! I guessed right!
It is currently vented down to where the carbon canisters used to reside.

Good call. That evap system seriously made the bike a pain to work on in certain areas with all those ribbed hoses.

I have read in the past where some have found the "long hose vent" can be a problem in strong cross winds. My '03 has no hose at all--the vent is open to the air right at the carbs with a T connection. This has never caused me any problems in very strong winds. My conclusion is that Mr. T corrected a problem that did not exist in later years by adding the hose. Of course the CA models had the hose to go to the canister.

FYI, if the carb bowls are not vented, the carbs will flood BIG time.
