use the 96 motor so theres no coolant hose cobble work and you dont need to bore the rear bushings.
gen3 for sure

Put the 87 jug on the 96 lower end with the gen 3

that'd run good, but the crancase volume is huge.

the gen3 might have the most build threads in the AF section, some guys cut the tube and extend it while raising the Y, some guys push em with a jack and open the Y from the backside. Pretty much whatever you can feel more comfortable with. Build a headstay from the dimensions listed in algavas thread or supply an email and someone will send you the drawing. Using that headstay and the stock lower mounts will setup where the front mounts need to be installed, get the 125 swingarm bushings, its cheaper to buy the allballs complete kit than the oem sleeve only.

Get started!
