Massive loss of speed, timing, or electrical??  By  outbakjak (Read 676 times)

OK guys, so I feel pretty stupid! I should have thought of this the first time I changed my stator and a broken flywheel key fell out, my timing is WAY off! SO it seems, that when I installed my first replacement stator, and I (like a total n00b would do...) pounded the flywheel back on way too hard with a mallet to make sure it was well seated, and cracked the woodruff (flywheel) key. This caused my flywheel to go out of alignment, messing with my timing, I think, lol.

So, the broken woodruff key has been GRINDING down the metal on, not only the flywheel, but on the cheap stock crank as well! Now, after purchasing a new woodruff key, the metal is ground down so bad around the slot where the key sets on the crank, that it's not doing it's job, the flywheel is slipping further and further still.

Timing or electrical? I think timing! I guess I really don't know what to look for when using my timing light, and a few degrees off makes a huge difference. Looked right to me, but I knew I couldn't be sure. That's what I get for not doing my research.

So I'm gonna make a trip to my local junkyard that just started carrying scooters, and try to pull myself a new (used) crank, hopefully this fixes my problem.

Man, I love my scoot, but it's giving me a month long headache. Purchased for $400, registered for $200, and $150 more in parts and service later, it's still a piece of junk . Here's to hoping that I get this baby back on the road soon!

Oh, yea thats your problem. If the flywheel is not aligned, the pickup coil fires at the wrong time, thus the timing problem you have.

The flywheel goes on easy but comes off hard. If you had to hit it to get it on something was wrong from the beginning. It just slides into place and the magnets keep it on before you put the bolt back on. Did you notice it broken from the beginning, or just recently? A new key cost around $2 or less and could have prevented this.
