I have it apart to replace a fouled spark plug and replace Air/Fuel filter etc..    I hear a lot about deleting the Evap-can on these, but can't find a good write up on this model.  It has one hose running from the fuel tank to the evap-can.  and two hoses running from the can to the efi-throttle body.

Do I remove and cap off both of the throttle body connection barbs? 

I think I remove the can and then run the hose from the tank up to a high point on the frame?   Near the air box??

I had already watched all those.   My CF800 is actually a 2016.   It has two hoses running from the can to the throttle body.   All those videos show them disconnecting a single hose from the throttle body..   (not two)..

I'm unsure. I know the tank has to have a vent and most often with a check valve to let air in as the pump take fuel out but not let fumes out so..if that one line is all the tank had, put a check valve on it.. and just plug the other two to the TB. It's OK to have pressure in the tank just not vacuum. 

I am wondering if that evap can with the extra hose to the throttle body, somehow has the check valve built in?   I don't want to remove the whole back section, but I don't see a check valve between the can and the fuel tank.

Hi caveeagle,

Here is my advice on removing any fuel tank breathing pipes, evap hoses, filters, traps or valves etc. 
Leave well alone!!!!!!!!!!!!!!!!!
Why....despite what you may have seen on the splinternet, one has to ask one key question....WHY!
Why do you want to remove the pipe, what are the benefits, or more importantly what are losses?
One simple key point to remember in the unlikely event of you being found in a ditch off some trail burnt to a cinder the forensics people will ask the same question. Why did he remove that pipe?
Manufacturers fit, design and develop fuel systems based on rigours testing against stringent laws to make sure the bike is safe and conforms to stringent requirements in each of the countries they are marketed in.
Removing a fuel system pipe especially one that permits venting or breathing of the system voids your insurance on the bike. All claims for property damage or personal injury will be void because you removed and or altered the fuel systems beyond what the manufacturer specified.
Whilst I am a great supporter of modification to the enjoyment of our rides, I ensure that the modification is such that it improves safety, in most cases goes above and beyond what the manufacturer specified. Especially when one is modifying Brakes, suspension, steering, lighting, electrics or fuel systems. For all fuel system modifications I ensure that systems and components follow the stringent off road/rally regulations with the components being purchased from reputable suppliers, never EBay or Amazon.
Enjoy your ride, stay safe.........Grand Master Splash & His Furious Ride
