I found myself with the smog can removed from my bike, though I didn't take it off myself. So I'm curious if all this plumbing I see threading it's way around my engine & carbs once made it's way to the canister.... and if it's a simple matter of removing all the seemingly needless plumbing and plug the various in/out-lets???

See below:

I assume it's a 790, right? If so it would be a bit different than mine but similar enough to tell you basically what must happen. There are nipples on each carb that are hosed to the evap system and those hoses get $hitcanned and the nipples capped. There is a hose to the right manifold (right on mine, may be left on yours) that also goes and gets capped. The tank breather i believe can be left alone since in now is just hanging open ended with the cannisters off. (tho it has that tipover valve in it)
The important part is the float bowl vent. There is a T fitting on a tube that connects the carbs. in the moiddle of it is a T joint where it connects to a hose. That hose must NOT be plugged. If it is the float bowls will overflow. With the EVAP system in place (on mine at least) the hose goes to a valve which opens when the key is turned on. The other side of the valve is wide open to the atmosphere. So with the bike on it's just the same as having a hose hanging down open ended. So just make sure theres a hose on the T fitting hanging down to below the bike. If you wish you can put some breather material in it to keep debris out of it. By the way, the "float bowl vent tube" is NOT connected physically to the float bowls, tho i'm sure you realize that having jetted these bikes in the past. It does vent the bowls, but via a passage where it connects to the carbs that goes to the bowls. Just wanted to mention that because one person thought i meant it was physically connected to the bowls.

Pat, heres a link to the directions for removing the evap system from the Bonnie..You can probably reverse engineer them and see what parts and hoses should be removed/capped off etc...

Thanks guys ,as I want to ditch this stuff too.I was riding with a friend a few weeks ago,he had all that stuff gone and it was a nice clean look.

Before you guys do this, consider what i just read in a post at NTBF. Someone said the Cal air resourse board is onsidering a new motorcycle inspection plan ! Trust me, putting the stock pipes and jetting back for a annual inspection isn't a big deal and well worth it. But reinstalling the EVAP system would be a real pain. And considering it doesn't affect performance you might wanna think twice about doing this considering this news. I'm not only NOT suprised to hear this, but i am suprised it hasn't happened yet in this overly PC state. If this happens i may well do what i considered a while back....get a rocket. I can't be happy with the speedy in stock form, but a rocket will be much more than adequite to say the least. Hoping for that rumored mid range bike...

Yeah, but i fixed it. Knowing what i know now it would be simple to troubleshoot and fix any problems with it. And it could go for the life of the bike w/o every needing repair agin. And thats a better option IMO then reinstalling it every year. If you do remove it tho, note that the hoses are very hard to replace if you route them as stock. (at least on the speedy) if i were to do it even knowing there were inspections to come. I'd get some longer hoses so i could route them temporarily any way they'll fit just for the test.
