Any merit in removing "Kalifornia Gas fummes Kanistor" crap from 1200 Sport? I removed plumbing and canistor from my old Breva and truly did not notice any differance in performance or mpg. I did however gain valuble space for a air pump. Will removal aid PCV in posible performance enhancements? Not a tree hugger but I believe in doing anything possible to aid our native earth. Don't really believe our cycles make a whit of diference on world pollution though. Just asking, if one were to remove said recirculation plumbing, what would be opinions on simply capping off at throttle bodies? :whistle:
 
Well, it's not just Kaliforn-I-a nowadays, it's global. Removing it will have no impact on running, outside of correcting the secondary air intake leak, the stepper motor being the first. It's recommended to connect each spigot to the other side with a single rubber tube... you should have enough to use with what you remove, as it supposedly adds to "smoother" low RPM throttling & idle. Upside for connecting the two is that you get to leave the spigots for future throttle body balancing, make life simpler when the time comes.
 
Thanks Todd. I left the tube connection between the 2 throttles on my last Guzzi. Just thought it would be cleaner doing away with all tubing. My UK " Carbtune" manometer has fittings that fit directly into throttle bodies. Your magic should do away with any low idle smoothness issues.
 
I was having trouble with the tank pressurizing and a hard-start condition when ambient temps were on the warm side.

I removed the canister and everything cleared up, it was likely just an issue in the system that could've been fixed but I could do this in my garage and gain some valuable underseat space at the same time.

same here with tank pressure. tubes and crap gone, tank pressure issue gone. that is some crap plumbing. :evil:
 
I had such negative pressure on the V7 due to the evap can that it would expand the nylon tank by half an inch on both sides when I took the gas cap off. Its a joke.
 
I had the same pressurization problems as well. Scrapping this canister and associated plumbing was the first mod I did to the bike. After removal I had a smoother idle with less surging and much less popping on decel. I simply plugged each connection on the throttle bodies instead of running tubing from one to the other.
 
I've had mine both ways. with the tubes connected and with screws plugging the holes at the engine. didn't notice a difference in either set up.
