Trx 70 stator replacement?

[Texas 200x]

I picked up a 86 Trx 70 with no stator or flywheel. Got another motor with flywheel and pullstart from a buddy except he already took that stator out too. So has anyone found a replacement stator coil that fits right in? Id prefer not to buy the aftermarket setup for 200.00 I see online. Thanks for all the info.

I messed around a lot with pit bike, TRX70, XR50 and XR70 engines/wiring. All of witch are CDI ignition. The TRX 70 is the odd man out in this bunch. You can get it to run with a pit bike stator, I think they cost like $20 or less on ebay. But the wiring isn't going to match up. I have made a pit bike motor run with TRX70 wiring and a XR50 CDI but I had to plug in wires that didn't match and hook 2 female connectors together so that didn't plug up. So if it were me I'd spend the $20 for a pit bike stator, make sure it has the pick up coil with it, it will work correctly with the stock TRX70 flywheel (I ran a TRX70 flywheel on an XR50). Then just study where each wire goes and figure how they plug up. That or if you want it to be more of a plug and play then buy the pit bike wiring harness and CDI as well. These parts are cheap but I think its a bit of a waste of money if you have any ability to follow wires and figure out where they go.

Hard to find oem ones......I do have a working stator though, no flywheel if interested.Let me know......

So are the pit bikes trigger coil mounted in the same spot as the trx? Or will it trigger it at the wrong time? From what ive been reading they are in a different position on the mounting plate. Or should I just transfer the parts over to the original mounting plate.

Where did you see they are different? I don't have any written documentation that proves they are the same or anything like that. But I did run a TRX70 flywheel on an XR50 and it ran fine. So that leads me to believe the pickup is in the same place. And since the pit bike stuff is a clone of an XR50 I can't see any reason why it wouldn't work. Im not going to guarantee it but if were me Id go for it.

http://www.3wheelerworld.com/showthread.php/144023-Bought-a-TRX70-and-need-to-learn-about-them Hey Blown331.....did you ever swap that crf50 stator onto the trx?? That would be a great fix for those bikes if it works as the trx stuff is pretty hard to find??

[Blown 331]

I was able to get spark so I did not try the swap. But I am confident it would work since I did miss match almost every other part of the 2 ignition systems. I still have that pit bike stator so I could try the swap and see what happens. But I don't really feel like it. Lol.

i have a bottom end out of an 86 trx70 that if i remember right still has the stator but dont know how good it is i will dig it out tomorrow evening and do ohms test and give you numbers to see if anyone thinks they are correct to work. if you want it or all of it sure we can work something out187579187581187585oh yea dont have some of the parts in pics will lok to see what i do have in case there is any you need also have a rear axle assy too thanks danny

Ok I thought the 50's had the pulsar in a different spot. I read on another site someones also caught on the flywheel a bit. They adjusted it a bit. Great info I appreciate it!

[Blown 331]

Now that you mention it I did have to adjust it. It was not a big deal at all and I totally forgot about that. It ran fine.

bear with me on colors as they are faded and i did not peel back tape y/r neutral switch g/w to grd continuity g/w to blu/w 94.9 g/w to blk/r .615k blu/w to blk/r .710k blk/r to grd .617k blu/w 94.8 parts left- kill switch, chain (stiff & rusted), shift lever, shift indicator, chain adjuster, rear brake spring, lever adjuster at rear drum, and brake pointer. hope someone can throw in whether ohm values are correct thanks and ya'll have a great day
