stock steering stem should be under 200,
hpd make a sweet +2 stem w/ clamps and bushings for like 269 shipped
u can buy any handle bars for it, anywhere from 35-130, i used pro tapers on my old pred, with the stock plastic key guage light assembley a little tight, but worked fine, otherwise u can relocate the key to the front plastics
grab bars go for like 35-70 depending on what u want
bumpers are like 80-120, had an ac on my 03 and that was around 85 i believe
plastic is about 200 for all, plus shipping through polaris, dealers may ask 130 a piece me dealership always cut me a deal
tires are about 60 a piece, and if u buy rims they run from 40-125 depending on what u want
u can buy a dg slip on for like 160, not much power gain but noise if thats what u are going for, the pro circuit sounds nice but i have heard alot good about big gun and thats about 500 for a complete system.
common defects, bad tranny's i never had a problem i think its mainly from people not knowing how to use the "clutch", 03 and 04 frames tend to crack, mine never did besides the rear fender brackers on the back of the subframe, rath racing offers some nice gusset kits for the predator though, some people had timing chain problems mine never did, motors tend to be a little loud, other than that its just like any other quad
