I've got a run quality issue I have to address with my PC5 installed. I'm gonna pick it up tomorrow from Woodys Yamaha and reinstall my PC5. Sled starts and runs but just not smoothly like it should. I may have gotten the #2 and #3 injector hookups hooked up wrong. Spoke with Allen and he's gonna send me out the map to reinstall just to make sure. In my eyes thats customer service always there to help you out after the sale. Hoping to get everything squared away so I can ride on Sunday. Anyone else ever had this happen when hooking up your power commander??

I have the same setup in my 12, 128" except I have a 40 tooth gear on the bottom.
Haven't had a chance to run any one yet but hope to get the chance Thursday.
I have put on about 30 mi so far. It is much more responsive largely from 22 grams less weight per arm, 66 gr total less weight than stock=quicker power to the ground!
We will see but it feels good so far!

I haven`t had my case apart yet, what is stock gearing in the 128"? are 2011 and 2012 the same? I was thinking of regearing but at 250# i might be too fat to pull it .lol

As far as I know the 11 and 12's are the same. 128"=24 top and 37 bottom.
The XTX's come with 23 top and 37 bottom.
I have 24 top and 40 bottom. 1.66 ratio VS 1.60 on a stock XTX.

What's your top speed with that gear setup.
