I got a deal on a 38.5mm Keinin PJ. It looks to have a power jet built-in. There is a two-wire harness on it that I asume plugs in to the bike's harness to read alternator. The guy said it was off a late '90's CR bike. I want to put it onto my TRX250R. Has anyone heard of this and how do I conect the wires to make the power jet work?

Just found out the carb is definitely off of a '97-'98 CR250R. Does anyone know where I can get an electrical diagram for this bike?

i have a 37 mm pwk airstyker with this power jet also , from 2000 rm 250 . been told just disconnect it and set it up , however when you pull it apart you'll see the needle jet is not changeable , presumably cause the power jet sets the amount of extra fuel flow ?? zedicus has one on his machine , i've not fitted mine but would also be interested in the wiring diagram , although i think you'll find its a potentiometer wired into the throttle ..

I have seen that exact carb ran on a 250R, just when putting it on don't hook up the power jet, and it will run great!

or remove all that crap and it will look great and run great.

I have plugged it off and it runs great! I would still like to know if I could somehow signal it with my harness and run with it. That way I could lean out the main and have it kick on when needed. This would be great for those few trail ride days!
Thanks!
Still lookin' for schematics for '97-'98 CR250R!!!
