quickest and cheapest is to build your own drops. you will need some 1/4" plate aluminum, 3/16" will work also. 5" x 9" if you want to retain the stock holes, 3 1/2"- 4" is a better look in my opinion, shaped correctly and skipping the stock holes and making your own. button head allens with wizlock nuts along with loctite are my fasteners of choice.
never had any unusual piston issues on my 94-96 vmaxes and always used oem for replacements. 97's had the piston/ring issue. put many miles on those old girls. only a few lean burns, self inflicted. to my knowledge they are still alive to this day. harder on clutches.
pipes, if you can find them, wake those sleds up. a timing bump along with high quality fuel is a cheap mod.
dont lift the rear too much as it upsets the handling of the non adjustable front end, unless you relocate the skid.
