Not a good day!

So yesterday I went to some local dunes with a group of friends and all was going well and then disaster. My EX was running great and then in 4th I goosed it a little and no juice so I stopped and then started her back up and I hear a horrible knocking. I got towed back to camp and decided to look at my oil filter and there were metal flakes everywhere. I don't know exactly what I did but I think I threw a rod bearing. Help me out guys my mods are in my sig and they really aren't the kind of mods that would blow a motor up.

was your timing off?

[Phillburt57]

I don't know but the motor was bone stock internally thats what is weird about it.

[trx400EXtreme]

how long have you had your hotcam in?

[Phillburt57]

That's the thing though is that the Hotcam never got in. I was waiting to get the 416 in before I put it in. It's still a bone stock motor. I have all the parts waiting out there but never got the time. That's why I find it hard to believe my 400ex blew up.

very weird but..how well do u maintain this bike? was ur oil low? and i guess ull be starting that 416 earlier then u thought :D

That's odd, but sounds like you might have spun a bearing. Don't hear that much on Honda's but I've had a Suzuki and Yamaha do that.

Good luck and wish you a speedy rebuild!

Maintained meticulously. Full tank of oil everything checked out perfect just a fluke I guess. Less than 15 hours on it is the worst part of all.

Did you check your jetting? Besides It now just gives you a good reason to rebuild
