need some info on the yz450f

i am sick of the problems with my honda atv and wanna get back on a bike.

how are these bikes throught the trails and how good is the stock shock?

The stock shock on the 426/450 is excellent and should have enough adjustment to dial it in for trail riding. This is just my opinion and depends on how tight the trails are but I think the 426 is probably better suited for trail riding than the 450. Keep in mind that they are bred to be MX bikes and you might want to look at the WR's if you are mostly trail riding.

The YZ450 is an exceptional motorcycle. They're extremely reliable, too. However, as Vibeguy pointed out, they're a Real Race Bike, and are a little high-strung. But they're a lot of fun, too, and in the end it depends on how you like to ride. The earlier ones are the least suited for trail riding, but it's correctable. Add flywheel weight. If it's an '03 with a stock clutch, you'll want to smooth it out some with a Hinson or GYT-R clutch kit. The suspension is set up for MX with a 160-175 pound rider stock. The rear shock is generally though of as excellent, and the forks as pretty good.

WR's have a 5 speed with a lower first gear, and the e-start, but comes with 15-20 extra pounds.

wide open trails and there is an mx track about a mile away from my house. i spend most of my time there. i dont want an e start because i hate dealing with batteries. whats the differance between 426 and the 450

I love mine for trail riding and wide open desert. I had to re-spring the rear end because I am a fat ass. Now it is sprung for 230 lbs. and I love it!!

whats the differance between 426 and the 450
10-20 pounds, depending on the specific year model, better forks on the '04, about 1-2 horsepower, depending on the dyno, one gear, and something like $1000. Or more. The 426 engine has a SLIGHTLY more civilized character to it.

      Brand new, still in the packaging Lexx end cap fits the stock muffler of 2006 & 2007 YZ450f and 06-13 YZ250f. Comes with a forest service approved spark arrestor and two different size tips. Don't spend hundreds of dollars on a slip on, this tip can be quiet and forest legal or loud and make power! Also a note for WR450 guys: get this tip and find a used 06/07 YZ muffler, fits directly on 09-15 WR450. $80 shipped free to the lower 48. PM, call or text 406-223-8789

      So I have a 2008 yz450f and I would like to add some LED lights to it to make it street legal. Mainly just a headlight and a tail light and turn signals if I need to (which where I live hand signals work).
      So where I need help is getting power from the stator to a battery. Wiring from a battery to anything else I got and understand and don't need help with (but recommendations are welcome). So my questions are.
      What type of power is coming from the stator. AC or DC? Will I need a regulator or rectifier? How do I wire something from the stator to charge a battery? What would that wiring look like? Would this stator work? Anything else I should know? Any help would be appreciated. Thank you.

      Alright so I’m new to the site so maybe this question has already been asked. I have a 2002 Yz426f and I want a new exhaust, it has the stock header and silencer and sounds amazing but I’d like a little more from it, I know I want the fmf power bomb header and am kind of undecided on the silencer, I see on fmf’s website that their silencer will add low end and slightly take from top end and the other way around but I’m looking for increases throughout rpm range. I do a lot of trail, hill climbs, jumps, and wheelies so kind of need good performance everywhere in the rpms. My question is what silencer I should get and the jetting I should get for the carb. Thanks

      2005 YZ450F, Athena Big Bore, Power Bomb, Q4.
      Ok.  Last fall after a decently hot day at the track, I noticed coolant leaking from the weep hole on my water pump after pulling into the pits.  Ordered an Athena re-seal kit, put it all back together and didn't really get a chance to ride it.  3 weeks ago, went out to the track, and after about 20 laps, it started leaking again.  Kept filling it with water to get thru the day, never ran anywhere close to dry or empty, jut a cup or 2 low.  Ordered a Hot Rods re-seal kit with bearing and also ordered a new w/p shaft.  Did it all again and got it back together, ran it, and as soon as it got to temp, it was leaking out of the weep hole again.
      So, what the heck am I missing?  I'm totally stumped on this one.  Is something wrong with my case cover?  Do I need to replace the w/p itself?  I'm feeling like I should've just ponied up for the Boysen in the first place, and now it's biting me in the butt.  Any help or suggestions is greatly appreciated.  Thanks!
