Hi all, I have an XT660R for dual purpose on and off road with 2into1 Metal Mule, BMC filter and PC III, and I�m going to put it on the dyno to make a custom fuel map but I don�t know if put the snorkel or take it off because I can feel the difference in better thorttle reponse without the snorkel, but in off road (dust, water, stones...) I�m affraid of let strange things come into the airbox.

Offroaders, are you riding with or without snorkel?
Cheers.
