I've got vapor line that sticks out below the bike between the rear engine mount. It's rigid and occasionally leaves a drop. I can smell fuel vapor once in awhile when I'm laying on the ground whipping down the undercarriage. If anyone can expound on deleting the vapor valve TinCup has mentioned please share your project.....thanks
The #62150-85 vapor valve in on the left side of the bike right near the steering head clamped on the frame; follow the black vapor hose and you'll run right in to it. It's a black cylinder just above the frame clamp; the vapor hose from the fuel tank is plugged in to it. The vapor valve is plugged in to another short piece of rubber hose, from there the line is shaped rigid plastic running under the tank and it drops down right at the rear engine isolator.
I removed the valve, used a longer piece of hose coming from the tank and plugged a straight vacuum connector in to the short piece of clamped hose and the hose from the tank; clean and discrete. I left the shaped rigid plastic tubing in place, all I did was delete the vapor valve.
Some will post that removing that valve is, ::: gasp ::: illegal. And so is venting crankcase gasses to atmosphere, and every other thing we all do to our rides Don't care, and I haven't noticed being followed by the black EPA helicopters, ether...
The gascaps are supposed to be vented, could a cap that won't vent cause the tank to build pressure......I would think yes? I know the cap gasket should be replaced every so often, how long since yours was replaced?

Truly....yeah not worried about inspections until they start emission testing bikes again. Does the tank have to come off to eliminate that small valve, it kinda looks like it may?

Yea luckily for me Michigan doesn't do emissions testing. No the tank doesn't have to come off.
Ok so this is what I did with the helpful info TinCup shared with me:
The valve looks just like a PCV (valve cover ventilation valve on older model vehicles) I removed the valve from the line:
Cut me a 2" piece of brake line to take it's place:
Easy peasy, the brake line idea worked out perfectly, the only reason I used a longer vapor hose was so I could completely hide the hose connector and make it look like one piece.
TUCCI, great idea adding this DIY mod to the database. You recognized a useless, mandated add-on and immediately corrected it. You can pretty much figure if the .gov wants something there, it's a bad idea
You motivated me to see if I could clean up that vapor line even further; I went to Auto Zone this morning and bought 12" of 7/32" (5.56mm) rubber hose along with 2 black clamps for the fuel tank crossover. Used alcohol to remove the imprinting on the new hose and lifted up the console and removed the current 1/4" rubber hose. The vapor hose is plugged in to a connector that comes off the fuel tank vapor line barb under the console; that hose coming off the barb to the connector is 7/32"
Took the 1/4" hose stub off the rigid plastic line and ran the new hose directly from the under console connector to the rigid plastic line; the new hose is smaller in diameter and cleaned up the neck area even further; grabbed a quick image then added the black clamps to the fuel line crossover; it's all about the details
