DRX 90 Won't Start

[bronco39]

Needing some direction from someone more experienced on these little bikes.
Have a 2006 DRX 90 - son was trail riding going up a steep hill and it just quit. Got it home and started looking for the issue.
Had very weak spark at the plug - changed plug, checked all wires, connections, etc. Cleaned stator and made sure it was dry and nothing got better. Tested stator with Ohm meter and got readings that were not consistent with what they should be (according to a thread I found on this forum) so figured the stator was bad. Got new stator - still very weak spark (not enough to start it). Tried bypassing the wiring harness and going directly from stator to CDI - no difference.
Any advice before I get a CDI and/or coil ?

Thanks

Well weak sparks only consistes of 5 thing's.. Bad stator, Coil, cdi, going bad kill switch or bad grounds... I would try to clean all grounds and wires. I had this same problem on 3 minis and I just replaced all old parts and it was fixed... I have a cdi and coil 65 shipped...

do you have stock teather and key switch?

Maybe I will have too see... We tear all that off and gose in the scarp pile... I will check thoe and let you know.

fomospede - not sure if you were asking if echo had stock kill switch for sale or if that is what I have on my bike. I have all the stock wiring harness plus an aftermarket kill switch wired into the coil.

If you buy-pass the old wireing and install new cdi and coil you should be good.. Let me know if you need parts... Thanks and good luck.

And also take the plug boot off and put to the frame and see if the spark is any better. I've had sevrale ****y boots too.

Thanks for the tips - I will try tonight and let you know if I am going to need some parts.
Thanks

Sounds Good!! Pm me for my phone number and I can go over it with you..:macho

My coil wire came out of the coil and the cover for the coil wire was holding it up to the coil just close enough to make it spark sometimes. We pretty much did what you did and added some grounds from the motor to the frame also.

Good luck.

Yep I've had the problem also..

Finally found the issue last night ! The ground wire from the CDI was broken somewhere up in the wiring harness - grounded it and all is well !
Thanks for the help
