ive got an '01 grizz w/240 miles on it. well yesterday i was climbing this hill and it started cutting out and almost died. what causes this and how can it be fixed? if i have to go into the carb,im goin to just go ahead and re-jet it. this is the first time this has happened to me and of all times for it to happen it had to be in front of my father-in-law who just baught a sp700 who also thinks if its not usa made, its junk...
