Just a thought...
For those of you with the cracked cases, are your keys sheared? If not then the timing is on spot and couldn't be creating problems.

Most people that have a problem with this end up with a sheared woodruff key. I have seen a few post that looks like the starter gears have let go and these problems have shown up in not being able to use the E start or a cracked case (actually side cover I think but not sure).
This is just my opinion on the stuff I have read here. Hopefully someone that has cracked a case can fill in the holes in my story.

Yamaha really screwed the pooch on this one. I would hope they would step up and make it right but I doubt they will
I havn't had a problem yet (knock on wood) and the $350 for parts sucks. I think at a min. Yamaha should offer a update kit for right around $120. To be totally right they should fix the problem though.

Is this case cracking syndrome still possible if you remove the idler gear and disable the starter alltogether? I seems I read one post and saw pictures of a cracked case on the kick starter side. Thats the one that bothers me the most.
Tim, I have a freind with a YZ450 and twice, he had it in the dealership for kickstarter repairs. He didnt elaborate, but the first was just out of warranty by a few days, Yamaha did fix it. Well, it happened again, they fixed it, but there was something in the case he said was broken in the kickstarter area, not sure, but I'd be willing to bet he had a sheared key both times, and they repaired the key the last time in. He complained it would pop back too. Now this was a YZ, so it never had the electric start.
