what changes would a blue or purple secondary make to a 90 500. what needs to go with it? some one offered to sell some springs and I have no idea if I can use them, or should even try? primary will get a mild upgrade when I get it sorted out what i need.
500 is fresh rebuilt .040, single pipe, 1.5"x133"
not sure on gears yet, but will be down a notch or two from stock.
primary use will be S MN ditches and trails.
Porting give a 500 much of a wake up call?
I'm loosing my mind, but as long as I keep the part that tells me when I gotta pee I should be OK.
