Some type of clamp on style air filter set-up, Dasa has a nice one but this mod is neccesary cuz stock filter doesnt seal very well.
Muzzy or DASA full exhaust, depending on what sound levels are tolerable.
Clutch kit, VFJ or Dalton depending on whether u wanna keep KEBC (engine brake) in tact.
Overdrive plate, several vendors have them.
38mm throttle bodies, DASA, Benchmark, and a couple others have them.
After these mods you may or may not need some sort of syphon brake.
In about that order. Some vendors can hook you up with all that stuff and when you buy from a vendor from forums, since the MSD is programable they can set you up with proper programs for the other mods you do and on top of that the customer service you get from them is top notch!!
SO.. Your homework assighnment is do some searching about the above mods and n the end you will be giving your rzr buddie fits. Soon enuf you will be craving a BBK, but that is next semester
