I got a cheap 1995 sportsman 400 that I wanna turn into a nice little mud bogger I'm wondering what spring would help with more bottom end where would that spring go in primary or secondary clutch.. I don't want anything to drastic I just want more tourqe when hitting the throttle and have no idea what to buy just looking for spring I don't want a whole clutch kit just don't care for top speed I'd like a little top end but willing to sacrifice a top end for bottem end I've never had a automatic atv only ever had manual shift atvs any help would be greatly appreciated thanks
