Thanks for the reply, how much was the FCR and where did you get it?

And did you install it along with everything, before, after?

I got mine for about $200 but they go cheaper all the time..check ebay or Thumpertalk.com or even YFZcentral. Mine came off a 05 yfz.

I ran it for about 4 months on the stock motor with good results, probably with a 160 main.

There are a few write ups on Zcentral on the swap, pretty std mod nowadays.

Here's some info
