So as goofy as it may sound, I do like to pedal my Raptor around. So I wanted some more gears for the longest and decided to tackle this mission. The cheapo Chinese freewheel is destroyed when taking it off. Just had it open up the side cover and lift the assembly off. Ball bearings all over the place. Screwed on a Maillard 5 speed freewheel, with 14T being the smallest gear. I can only use 4 out of the 5 gears. The derailleur rubs on the motor side cover in 5th gear.
I used a cutting bit, 2x4, Royal Purple motor oil, vice and a router for a poor man's machining job. I got the 255mm rotor installed on the rear.
