Hey all,Thanks for the explanations. Boggy, I put in a new plug back when I got the bike started for the first time. A few months ago, but it's only been started once since. I may give charging the battery fully a shot, but it seems like this is much more of a mechanical issue.Based on Arizoni's advice, it sounds like the Sprag is binding up, not disintegrating (though that may also be the case I suppose). I think every now and then the sprag will lose its grip on the crankshaft, and those are the times when I've been able to kickstart. When I get the "slipping" feeling through the kicker, it's smooth, so it doesn't feel like teeth slipping or grinding off a gear. More like a smooth slip. My best guess is that the sprag is locked up so tight that the clutch plates slip before the sprag does. So there's no movement in the duplex primary chain, which explains why the tappets won't budge when I get the "slipping" feel through the kicker. Thoughts?Thanks guys.
I have read through all of this mainly because I had a run away electric start and wonder if I have damaged the sprag clutch. This sprag clutch sounds like that mechanism one finds on top of a rope start lawnmower. I have plans on replacing the starter solenoid, but wonder how does one check to see if the sprag has been damaged. Also, after reading all the comments above, I have wondered if the electric motor itself was ever tested to turn over?
I don't understand your last sentence? If the starter motor isn't turning you can't get the sprag noise. And "any" sprag noise is bad noise. That's why I've avoided the ES for 831 miles (I used it a few times in the winter of 2010/11 when I first got the bike running) & I always kill the engine with the decompressor, never the key. Once in a while, shutting down with the key will fire the plug coming up & it will drive the piston back down the wrong way. Horrible noise. Can't happen with the decomp. I could do it (rebuild the sprag), but I don't WANT to. Ever. I want the ES for things like killing it in traffic & other nightmares. Actually, I don't think the AVL was ever meant to have an electric starter. And low battery voltage is a starter's worst enemy.
