Saw a picture on Facebook last night of Josh Grants Yamaha. They had FMF build a pipe that while it still exits the back of the jug it comes around the left side of the jug, around the front and then heads back along the right side in an attempt to influence center of gravity.

how much longer will Yamaha stick with that engine? if it "works" why aren't they using it on the 250?

if they go back to a conventional design are they conceding it didn't "work"?

I'd sure like to know what they really think of that thing at this point.

Grant rode well @ the Monster Energy Cup, Justin Brayton rode it better than he did the Factory Honda, and Millsaps got 2nd in SX last year with it. I think the worst thing Yamaha did was have Bubba ride it. He crashed it all the time and he drew alot of attention to it.
Yamaha hasn't even made their 250F fuel injected yet. I think they're in a financial bind like everyoe else.

Carnad is the guy to watch at A1. He's been out a long time and off the bike longer than anyone, interesting to see what he still has. I'm thinking it will take him a couple of races to get his pace back. If he can.

The rest of those guys it's just coming off the Thanksgiving/Xmas break, hope they can all do that that better than I do!

Don't really have a favorite. I just want everybody to stay healthy so we can have some competition through the whole series. It wouldn't make me unhappy to see somebody push Barcia off the track. Give some of his own medicine like he gave in the Lites.

I doubt it has anything to do with the center of gravity. It's more likely for easier access to the rear shock and heat dispersion.

more likely length of pipe to build the desired power-band for the bike...

The old pipes were curled around in a loop beside/behind the rear shock.

who know. this was one guys post on the picture but in hindsight he may be guessing?
"Joe Gibbs Racing had FMF make the exhaust for them like this to move the muffler forward, giving the bike more nose weight and changing the center of gravity on the bike."

Whatever the pipe design, that is a sick looking bike. I love the black frame and swingarm.

It's the header from Coach Gibbs' Corvair.

One of the "popular" mods to the YZ is a kit that moves the motor forwards a bit. I can't remember how much but is was only 13mm or so.
This is one attempt to make the front end steer better.
I ride desert with guys that have them and they love the damn things.
