I had a 500 xcsp it got around 10-12mpg. I bought this one with 1400miles on it. at first it ran like crap on the
low end. so i jetted it down to 410 mains and middle in the clip. Now it runs fine ,plugs are tan to light brown
but this thing just drinks gas ,oil usage is noramal. i was riding in some fresh snow but 6mpg seems low.
any ideas on what going on?
