yup......IM HOOKED! went to corral canyon today near san diego. lots a trails, and some tight single track and had a blast! wasnt sure what to expect in those conditions, and it was the first time riding the bike, other than around the neighborhood. it pulled great, , never had plug issues, never had any stalling issues, ran a gear high and it muscled up everything with ease. im coming off a 250f which i considered fairly nimble and easy to ride, but the 500 seemed fairly easy to ride also. i was surprised out how easy it was. very impressed! i cant wait to take it back out there. bottom line, i dont think this will be a bike i get rid of anytime soon. glad to be back on a 2 stroke also, forgot how fun it was to get in the pipe and take off! only issue i had was, hard clutch pull got to me after a few hours, and when i shut down to wait for buddies to show up, i was in some awkward terrain and slightly off balance so kicking was interesting. usually just got off the bike and kicked with my left foot. so on the list of stuff to do is a compression release and somehow lighten the clutch pull.
