How to identify what year stator/flywheel help needed

Post by Unchained »

I picked up a good running 87 (83H) motor for my 83 Vmax project but the motor was in an 85 chassis with an 8U9 cdi. Is it safe to assume the stator and flywheel is 83-86? I can't find any Yamaha part numbers on either but there is a few stamped numbers letters so any
help here is appreciated. Thx

- Stators 5 different
1981 SRX (Original) P# 8K4-85500-10-00
1981 SRX (Updated) P# 8R9-85500-10-00
1983 P# 8U9-85510-10-00 without the hand warmer coil
1984-86 P# 80N-85510-10-00 with the hand warmer coil
1987-1991 P# 83H-85510-10-00 Yamaha changed the charging coil in the stator to a higher output coil, by doing this the secondary coil output went up from 18,000 volts to 28,000 volts ,but you also have to use the 1987-91CDI as well as, it is different to accommodate the higher voltage of the charging coil in the stator.

Check the ohm reading with the RED & Red-White wires if it is a 84-86 it will have 10 ohm's if it is a 87 up it will have 50 ohms. Hope this helps you out..
