Made the move from 4 to 2!

Just signed the papers for my 2013 yz 250. I get it this weekend and I am so damn excited. Have been riding my 07 rmz 450 since april. It was my first bike ever and I've only driven a 2 stroke around the parking lot at the dealer lol. The yz only has about 14 hours on it so she is pretty much brand new. Dealership owners bike. I don't have a whole lot to say and really have no point to this post. Just so damn excited haha. Cant wait. Here is a shitty pic I took today. Sorry in advance if you took the time to read my rant lol. Hooe to chat to some of you in the future. Will hooefully get a few decent pics this weekend. Bunch of us going out on a beauty woods trail and eventually end up in a pit with a few small jumps and some nice hill climbs. Take care! hope I enjoy my yz half as much as my rmz. So pumped


Welcome to the yami 2smoke section man...and I feel ya I'd be excited too! I know you'll enjoy it just as much if not more than your rmz! Yzs are awesome bikes and anything you need these guys are great at helping you out. I'm fairly new here myself and now I'm trolling it a couple times a day Lol. Enjoy your bike man

ihings I would look at asap if it was my bike, Squish, and ignition timing.


Squish is to big stock, its a poor design. it causes sloppy lowend throttle response/power, detonation on pump fuel (pinging, leads to engine meltdown/failure) read this thread, its very informative


than u measure to see what you have


once you have the measurement, send it to tell him what fuel you want and he fixes the sloppy huge stock squish (.070-.080inch)

will have less spooge, more power, better lowend power, better throttle response and smoother running on pump fuel (if you choose pump fuel)



and the timing is hit and miss at the factory, here is how to set the timing. (set to stock or retarded 1 degree)

Was the dealers ride he has it all tuned in. Forks have been sent. Jetting is perfect and he weighs the identical weight lol. I will absolutely still read over all the infor and I do appreciate it man. Thx

He like I said has out 20ish hours on it since he got it. Him and his shoo mechanic had it as sort of a pet project. Very trusted guys but like I said I aporeciate the info and it will be read and checkes. Thx again man

Ready to roll
