I just bought a 07 Brute 750i with about 600 miles and its a turd off the line. I can barely pull the front tires up. It seems to perform well throughout the rest of the power band. My 08 Brute 650i walks it pretty good from the start through the whole power band. Is it a jetting issue or maybe a dirty carb or gum in the jets? the last guy didnt ride it much, only 59 hrs in the first 2 yrs. Oh ya both quads are bone stock other then 26" mudlites on both. Any info would be great. thanks
