THIS WILL WORK FOR REPLACING A BAD STATOR OR IT WILL ALLOW YOU TO ADD 6V OR 12V LIGHT KITS, FOR NIGHT RIDING.. USES THE STOCK HONDA FLYWHEEL ON THE LISTED MODELS IT COMES FULLY ASSEMBLED AND WITH NEW LARGE ORING AND CRANK OIL SEAL. SOME MODELS WILL NEED COMMON BULLET CONNECTORS ADDED TO THE BIKE/QUADS HARNESS TO MAKE THIS UPGRADE. TRX90'S WILL HAVE TO ADD A PINK JUMPER WIRE IF THEY WANT TO KEEP THE REV LIMITER. BUT_WHO_WANT'S_TO_KEEP_THAT_? (: THIS IS FOR 85MM ID FLYWHEELS, LIKE THE STOCK HONDA CRF50 CRF70 XR50 XR70'S AND OTHERS HAVE. THE DIAMETER OF THE STATOR CORE IS 83MM IF RICKY'S HAS 90 WATTS THEN SO DOES THIS ONE !! (: CRF/ADD/LIGHTS$54.99 SOME COMMONLY USED TERMINALS Hey, I just wanted to say that I made an order for a few things, including the TM1 and TM3 bullet connectors. I received the order today and got the connectors on my workbench. They solder great with a warmed up regular pencil-style soldering iron and 60/40 solder. No (special) flux necessary for the nickel plating. Something you guys might want to put in the description. Thanks again for the fast turn around!
