Yikes!! Is that out of a Yamaha YFZ450? The only reason I'm asking is because I have two Yammie cranks that look just like that one here in my shop right now.

Yes it's a YFZ450. That one happens to have aftermarket lower end components as you can see, but I've seen other pictures like this one on the web before. I'm wondering if these people are riding these ATVs with worn cylinder bores. Years of replacing two-stroke pistons reminded me to replace the piston on my YFZ. Last year, my cylinder measured slightly out of specification. This year I replaced the cylinder as soon as I noticed the oil smelled like fuel.

So it's "A yfz450", not "YOUR YFZ450" then , correct?
