What years cross on the stator and pulse with a year model 1987 and will parts from any other yamaha work as well? Thank You, Vincent.

Sorry Vincent, but the 1987 TW200 was a "one year" bike -- the parts you speak of do not interchange.



If you get the stator, pulser coil, engine cover, and CDI from a later model bike it will work for you though with some "fiddling".



I was also able to convert my bike to run on a yamaha TTR stator/pulser coil/cdi setup, and that was very cheap on ebay. It all depends on your mechanical ability/financial situation, I suppose

operose, Thank You I know of an 87 for sale needing those parts in O K shape for $500, I think I will pass I would guess dealer parts will be costly.

Just changed cdi, stator coil and pulser on my 87 into over 500 in parts after shopping around. Stator coil read out of spec on my ohm meter, but so did my new one. I have found that if you disconnect the brown wire on a bad cdi the bike will run. But don't ride it that way. Does the bike not start?

From what I am told it does not run everything is fine compression, carb so on, two techs the owner had check it said he needs those parts........

So greendub you are saying your problem was the cdi not the stator/pulser? If so I may need to buy your old parts. let me know you have them so sale?

 

[greendub]

Cdi i want to keep. I can sell you a pulser and stator coil but the wires were cut at the end. Bike had a mouse problem when i bought it. They read in spec. Sator coil reads out but same as my new one

Are the 87 stator and rotor mechanically different? Or is it just wiring?

 

[Ayers Garage]

Judging by the factory parts diagrams, the stator is significantly different beyond just the wiring configuration.



The Rotor is Yamaha part number 3NS-85550-00-00



It fits only the following...



1986 BIG WHEEL ELEC START - BW200ES GENERATOR

1987 BIG WHEEL ELEC START - BW200ET GENERATOR

1987 TRAILWAY - TW200T GENERATOR

1987 TRAILWAY - TW200TC GENERATOR

1988 BIG WHEEL ELEC START - BW200EU GENERATOR



The Stator is Yamaha part number 2JX-81410-M0-00



It fits only the following...



1987 TRAILWAY - TW200T GENERATOR

1987 TRAILWAY - TW200TC GENERATOR



The Pulser Coil is Yamaha part number 2JX-85580-M0-00



It fits only the following...



1987 TRAILWAY - TW200T GENERATOR

1987 TRAILWAY - TW200TC GENERATOR



The CDI box is Yamaha part number 2JX-85540-M0-00



If fits only the following...



1987 TRAILWAY - TW200T ELECTRICAL 1

1987 TRAILWAY - TW200TC ELECTRICAL 1





All of these parts are still readily available from Yamaha parts channels. The prices are generally the same as the 1988 and newer stuff which is obviously more common.
