Cool Valve Adjustment Scare, Turns Out I'm an Idiot

So I had to post because I'm both relieved and feel like an idiot.

I just did my first valve adjustment on my 250, having never done an adjustment before and after it was all said and done I start her up, and I hear rattling noises. Crap. Did I do it wrong?

It gets worse as a rev it higher, I'm thinking either I jacked up the adjustment or somehow messed up the cam chain tensioner, I hear the noises on the right side.

I go to disassemble her, and low and behold-- there a 14 size wrench hanging onto a bolt on the triangle mounting bracket. I take it off and go for a spin. Problem solved.

Glad it wasn't a real problem! Mechanics have been leaving tools inside engines since they were invented, sometimes with catastrophic consequences.

Guarantee you won't do that again!

Glad it didn't get jammed somewhere and cause major damage.

Live and learn.
