So on the Warrior, there are three common places to relocate the rectifier:
1) in a chin scoop. I did that on mine.
2) mount it on the right side and actually display it. You can polish the fins and it looks pretty cool.
3) under the bike. You run a strip of metal from one side of the frame and bolt it to the top of the metal strip. There is room up under there between the frame rails.
All three have been proven to last over the years.
Oh!
There’s a 4th: under the tank on a plate. Kinda like a coil relocation plate.
Here is the open pulley on my Warrior.
