Eh? Honda CR500 RUNNING BACKWARDS!

So I installed a Service Honda Lighting stator and rotor kit in my cr500 along with the vortex cdi they offer with it the other week. I have ridden it a few times while I have been adding this kit with no problems besides a very difficult starting bike. Today I added a small speedometer and went to test is out and when I started it (two separate times) it started and ran backwards. . WTF? all I can think of is that it has so much advance that it fires too far advanced and throws it around reverse rotation and continues running in reverse rotation. Unreal.. I bump started it and it ran fine in the correct rotation. But I would like to be able to kick start it obviously.

Any ideas?

Yup, can you retard the timing?

No. Service Honda puts a part on the stator plate that prevents any timing adjustments since the cdi they have has preprogrammed timing curves built in. .

I figured that was the case. I got nothing other than; 2 strokes are cool because they can run backward. SkiDoo snowmobiles put reverse on their sleds that way.

Well i stopped down at the shop on my travels tonight and kicked it one more time and it ran the correct rotation. . So i guess it's just a roll of the dice if I'm in forward or reverse

I'm surprised it hasn't kicked back and launched your knee into the handle bars. it will at some point.

Oh it tried. I have a twisted ankle and a rip in my jeans where the kicker just missed my shin.

Yeah i would contact the company that built that part and ask them for help. The only other question I have to ask is when was teh last time the topend was rebuilt. I know I have heard of this happening when one is really warn. But that was someone stalling it on a hill and it rolling backwards just right.

Bluhduh

Top end is fresh with tons of compression. I emailed the "tech support" at service Honda which made the parts to see if he has any suggestions. Not to impressed with a company you can't even speak to on the phone with technical support questions. Next street cr500 I build will have a different setup for ignition if this doesn't get a remedy.

keep me informed

I was thinking of this kit for my 97 cr500.
Let me know how things turn out.
I have a battery powered sicass lighting kit and continue to search for an ultra rare baja designs or eline external stator.

I've heard that you need to change your starting to a four stroke method with that kit because it doesn't spark every time at low rpm like the stocker does, you need more kick rpm so it doesn't kick back and run backwards.

So far everything works well. the starting issue is a minor detail I will soon have ironed out, You should consider a trail tech lighting coil. if you run LED lights you will probably be fine with a 30 watt coil. If you feel like dropping the money on the service honda kit I will say it does work. only complaint I have is with the extreme advance making it a little tough to start.
