Evap removal from V7III

Godfrey said:
I took some pictures while working on disabling the evap can yesterday. Hopefully this will help someone out there... :

Illustrated Procedure:

- remove seat​
- remove left side panel (three bolts)​
- remove starter cover (two bolts)​
- locate vacuum tap line from manifold to canister under the gearbox​
​
View attachment 13673

- cut vacuum line and block it (I glued an aluminum slug in place)​
​
Follow the line and cut it in a convenient place, then block it ... particularly the upstream side that comes from the inlet manifold.​

View attachment 13674

- locate breather line with valve connected to canister​
- cut breather line above the valve and below at the canister inlet​

View attachment 13675

View attachment 13676

- leave the breather line open ended behind the starter ... put a filter on it if you worry about environmental dust getting into the tank (but it ain't going to happen... :)​
​
- replace starter cover​
- replace side cover​
- replace seat​
​
Hope that's clear ... ask if you have any questions.

Great explanation, thanks.
I realised I needed to do something as my tank gasped loudly when I took the cap off. I plan to remove the evap canister when I get more time, but for now I've simply severed the vacuum pipe down near where it joins the canister. To plug it, and keep the vacuum intact, I lightly oiled an M8x30mm button head machine screw (an old disk bolt) and screwed it tight up the vac pipe which it blocked completely. I then treated the sealed end to "belt and braces" cable ties - crimping the pipe even tighter to the bolt. I left the pipe from the tank overflow to the canister (with the little filter in line) intact. Do you think that'll be OK until I get time to remove the whole canister and gut it - to act as a sort of catch tank, or should I chuck the canister and vent to atmosphere?
 
I just removed the entire canister. I preferred not to gut it as I wanted the ability to reinstall if necessary. As it happened I traded my V7 for a V85TT recently, and the dealer was happy to get the canister back so they could resell the bike in stock form!

The only issue I had with venting to atmosphere was a gassy smell in the garage for a while after riding the bike, which was annoying! Some people added an inline fuel filter to the vent line which would help with that.
