Emissions Removal

This is how you remove the extra little goodies that come on a CA model VFR.

Here's what you do:

1. Removed the canister and most of the brackets that held it on. Leave the bracket that's on the left side, as this bracket is also used to hold the lower cowl on. You should secure vacuum hose that runs up to tank vent by fastening it with a zip-tie to the radiator hose. Make sure it is routed so that any fuel that may overflow from your tank does not come in contact with you head pipes.

2. The other vacuum hose that was connected to the canister goes to the Evap Purge Control Solenoid Valve. You might also want to pull the Evap Purge Control Solenoid Valve. That's the barrel shaped valve located on the right side just below the frame beam. It's connected to the canister by a vacuum hose. Just disconnected the solenoid wire (leave that in place) and removed the solenoid. Next trace the line from the solenoid valve back to a 4-to-1 connector that feeds the throttle bodies. Remove this vacuum hose and cap the open hole in the 4-to-1 connector, which prevents air from leaking in. A bicycle intertube cap with a little black silicone works great for this.

Basically, your tank will now be vented to atmosphere and you won't have any of this other crap to clutter up the bike and add weight. Besides the weight, the biggest advantage is that you will be able to access your oil filter much easier. Of course, if you went on a diet it would make a bigger difference in weight.

Thanks for the advice. I removed the EVAP can and I had a problem with flooding. This must have been caused by the lack of a vent since I plugged the lines. With the lines open the problem seems to have ceased.
