I'm installing a Engine in a 2009 YZ 250F please help ASAP

I'm installing a Engine in a 2009 YZ 250F and the races/spacers that go in the back of the engine that the swing arm pivot bolt goes through is there a left and right correct way to install these or is it just press them in and install the engine?

The cases are a little differant on each side it looks like one is deeper than the other I saw this after i pressed them in-

(Other bike)
2ND question- My kids 2009 YZ250F seems to be electrocuting him when he lands off the jumps some times ever had this happen to you? I have gone through the wiring a couple times and checked all the connections they all look great-

He is getting electrocuted when he bottoms the bike ? Is he wearing boots/ socks and gloves ? Does the bike have grips on it ? This is a good post ! Lets get to the bottom of this , it should be interesting !

Ha Ha that is kinda what I thought...but he says it feels like it was electrocuting him IDK.. hey your they mechanic right?
I have herd of this before on a 2009 RMZ 450 and it ended up (after I made fun of the kid) he had a real electrical problem, hell IDK and from the sound of it you don't eather?

Answer to question # 1 YES the races are the same left or right side- I pulled the races out and they are the same-

This engine is a pretty trick MOD 270cc with a shit load of cool stuff..I hope it hauls ASS!!

After a while I would just use my nuts to ground out the bike, felt good.

Dude don't try and play it off on here like it's not your new training method.

Wrap tape around handle bar under kill button we had the same problem on a bike and this fixed it.

Very interesting to me. Can he tell if indeed its the left hand ? [ kill button huh? must me moisture all the way through the glove yes ? to conduct electricity ?] In all my years this is a new one for me . Certainly a kill switch malfunction could send power out the top , i mean there is enough I suppose . Cool post , I'll remember this one.Thanks
