I got one that i just put in last winter. I have just a stock shee with t-5 pipes and the singel carb and some othere miner stuff. I love it for the trails its gives u great low-end and its also adds to the mid-range. some ppl say it hurts topend but if it did i dident notice. I would look for the trinity set up like i got with a 35mm carb unless your shee has stock pipes than go smaller on the carb. The jetting is not hard if u call trinity they can tell u how to jet it for your shee. The pic in my sig is the one i have which is made by trinity but i have the airstriker 35mm carb. If u have any othere questions just PM me.
