This may be the best way to fuel your 2020-21 500 or 501 EXCF/XCFW/FE or FE-S.  It needs to dialing in or fooling with.  The check enging light WILL most likely come on, when using this, but it won't hurt anything and will go away.  It's just the ecu figuring it all out.

     It provides enough fuel, like our piggyback programmer, to fuel the bike using our exhaust end cap and intake tube. You can use without the intake tube and leave the reeds in as well, if you want. It's a 13:1 to 14.5:1 air/fuel ratio, through out the rpm range. It's easy to install

 

THIS KIT ONLY APPLYS TO USA AND CANADA BIKES.
