Right now it is 13t on bike to 17t. Inside chain case top sprocket is 17t, bottom is 16t. What are your thoughts on this for a 2011 yz450f? Also are there any options as far as a better chain tensioner that wont break? Thanks

I have the same bike and set-up, but my drive sprocket(Top inside chain case) is a 16T and bottom is a 17t. I was running a 17/17 and I needed more bottom end at my elevation. That is why I dropped to a 16t.

My CR500/TS 137 which makes a bit more power than my 11 YZ is geared 14:16 main chain 17:20 chain case. It's just about perfect. I think it would work great on my YZ.

It was a different bike on an older kit (WR450F on a 2012 ST), but I messed with gearing for a while and also ended up at 14-16-17-20. That seemed just about right. I had also flipped the chaincase sprockets, but that made my gearing way too tall.

Thanks guys. So when you say 17-20 in chain case, is that 17 on bottom, 20 on top?

No, 17 top, 20 bottom, which is stock for the older kits. Flipping it to 20 top, 17 bottom made the gearing too tall for me.
