stripped starter gear?

[brute650i]

I believe i have sheared the teeth on the starter today. I finally got it back together and noticed there was a clanking when i tried to crank and then when i went to move it back into the shop in clanked 1 or 2 times then wouldnt turn the motor over but you can hear the starter turning and it would try to crank with pull rope until i broke the rope.

What is involved in fixing this? Could the dyna CDI cause this I read somewhere on another forum that kawi had told him thats what was causing it. Its just weird that it happed when i put the dyna on there literally have 1 mile since dyna and now this.

any input would be appreciated

The CDI kickback causes this. Some do it, some don't. Take the side cover off and it will be staring you in the face right behind the flywheel. There will be about 10 teeth missing off the ring gear.

if i leave the cdi on will it do this again any way to fix this issue.

can this be done by someone with minimal engine experience with a service manual.

its not difficult, you should be fine with the manual

All you have to do is give it a small amount of throttle when you start it usually. Another CDI from the same company may not do it.

You can do it if you have a puller to get the flywheel off.

Can you explain alittle bit more about what is happening. I dont want to fix this then first time i try and start it shears the teeth again because of the dyna.

Thanks for the help

it's called Kickback. The CDI advances the timing at startup. This can cause the cylinder to ignite prematurely which sends the motor turning in reverse, for just a split second, while the starter motor is trying to turn it the other way.

My prairie has done this since 2004 since I put the Dyna on it. I haven't broken any teeth.

I run a 6 degree key and the Dyna CDI. so I blame it on that.

so in short it will more that likely do this again with the same cdi i have stock timing key in. I have the worst luck with this bike

If your battery is low, it can cause it to crank slower which will heighten the problems John stated.

The advanced timing fires and tries to push the piston down before it comes all the way to the top. And because your starter is engaged, it can break teeth off of the weakest link. That would be the ring gear teeth behind the flywheel.

I've broke two, it's happens to me, just as I'm letting off the key, (kickback) thinking it was going to start and it didn't, so hold it on a split second after it starts.

Haven't had a problem with the VDI, just the Dyna
