Solenoid/Starter Diagnostic Help . . . .

Most of the time the e-start works great. Several times per ride or even on the initial startup, though, when I push the e-start button, the solenoid clicks once but the starter doesn’t turn. Absolutely nothing happens after the solenoid switches. Kicking fires the bike up no problem when this happens.
I’ve learned that if I move the piston even just a few inches with the k-starter and then push the button, the e-start fires the bike right up.
That fact and that this happens sometimes after riding for a while makes me think the problem is not a weak battery. Also, we put a volt-meter on the battery and it’s pushing out 12.8 v. I didn’t measure amperage though.
This started happening within the last couple of rides -- At first, I attributed this issue to a loose wire caused by my drops, get offs, and at least one attempt to move a tree (am a pretty new rider). Given that it seems to fire up if I just move the piston a little, I don’t think that anymore.
Any thoughts you have on this and what to check would be much appreciated -- loose wire (seems inconsistent with starting after simply moving the piston)? weak battery? auto decompression issue? . . . Thanks for any help on this.

I'm sorry I won't be able to help you much with the problem you're having other than to say the manual makes mention of this issue. It states that if the bike doesn't turn over with the electric start to use the kick starter. I have never had this happen personally but it sounds like it's happening way too often for you. Good luck!

The constant clicking with new battery would make me quess solenoid, but the intermitent problem that is remedied by moving the piston with the kickstart would tell the starter isn't getting enough amps (or just isn't powerfull enough) to kick it over at the point of highest resistence (at other positions in the stroke it can generate momentum to push it through etc.)

It is either the solenoid or the battery. Most likely the battery. Try another battery from a street bike and see if it turns over or put a meter on your battery and determine if you have a full charge. If that checks out get a new solenoid and you will be good to go.

I am going to conduct add'l tests on the solenoid and battery tho, since it (a) it has gotten progressively worse (maybe compression has gotten better as the parts have broken in) and ( seems to happen too often to be the piston stopping at just the wrong point . . .

Well, looking on the bright side, I can say my WR450's teaching me alot more about dirt bikes than I knew before . . . .
