check this out, the stem will hit if you use big bar adapters. i did one on a stock stem but had to use the regular bars. it came close but did not hit. as far as brackets, i had to make my own, real easy with a grinder, but do use locktite on the bolts that hold the brackets to the quad, one of mine fell off. your gonna have to hack the crap out of your plastic to get it to fit and another caution is the tank may not fit straight and level as mine didnt. to fix it i had to fill it up with boiling water and use whatever i had to reshape the damn thing. it was a pain in the ass but well worth it in the end. i can send you a pic of it all mounted up if you like. as far as the brake lines and stuff go when i did my personal bike i changed the lines, stem and just about everything else but when i did my friends with the stock stem i didnt run into any of these problems. what bars are you running ? also did it come with the rubber grommits and steel sleeves to bolt it under your seat ? get back to me man ive dealt with every situation on these tanks and still love them. later
