'14 YZ450f head

Thanks for the info. I've got a GYTR Head on my '13 YZ450 and really like it. If I get a '14 I'd like to put it on there. Rode a '14 this week, but it was on a sand track and the owner had a smooth program in it as well as the stock pipe and gearing....so it was difficult to tell a whole lot about the motor. It seemed to be somewhere in between a stock '13 and my modified bike with GYTR Head, Akropovic pipe, hi comp piston, and GYTR flywheel. If I got a '14 I'd like the option of putting on my low hour GYTR Head. Just a thought. As for the rest of the bike, it was WAY easier to throw around, much more nimble, suspension about the same (excellent), front end felt really planted (I have the engine relocation kit, linkage and radiator lowering kit on '13), overall I really liked it. Thanks.
