More work to ride a 400f or 250f????

I currently own a 99 400f and I am considering getting a wr or yz 250f instead. I am looking to switch to the smaller bike in hopes that it will be easier (less of a workout) to ride than my 400, due to the reduced weight. I am wondering if it is indeed easier or not. Do you have to ride them hard like a 125, or can you let the bike do most of the work? How about jumping the two bikes, Does the 250 jump differently than the 400s? Is it harder or easier to clear doubles...? What do you guys recomend WR or YZ? I ride both MX and trails. THANKS and Merry Christmas

I ride a WR426 in woods exclusively, and am also trying to decide on going to a 250F for the same reason. I've only ridden the WR250 (de-restricted) for comparison. The 250 feels much lighter than the numbers suggest, probably because the weight loss is above the roll axis. The 250 also corners easier in the tight stuff. The 250 is much less fatiguing to ride at a faster pace, but I'm not so sure about the slower stuff. The 250 requires much more clutch action in situations where you could just dial the throttle for various amounts of tractable torque on the 426. Also, the 426's ability to lift the front at will or jump obstacles on short notice with just a blip of the throttle lets you get away with making last second reactions, where the 250 isn't happy unless it's wound up ahead of time. The 250F is like a more tractable 250, with a slight power disadvantage- it's a lot of fun in the woods, but I'm afraid I'll miss that instant grunt. Now I'm also considering a YZ250, to get the light weight and quicker handling, while also having some snap on tap.

I went to the track in Easton Maryland with a couple buddies. Ones got a KX500 and ones got a WR250F I have a 426F. The WR250had to grab another gear to barely clear two 35 foot doubles . The KX and my 426 had no problem in 2nd gear! I rode the WR and it has to be ridden harder than a 426 to get the job done. I'll tell you this the 250 Felt alot lighter and was still a blast to ride :)

I rode the WORCS series this last year and borrowed a buddies wife's YZ250F for a muddy Washougal race. Was sold. Waited 4 months for the first 250f to arrive at the local shop and bought it that day. Still have my 426 and use it for desert races and big outdoor MX tracks, but when the track goes through the woods or is a tight hard-packed course I pull out the little bike. Not even close to the 426 in power but when you are bouncing off of trees and having to pick your line through roots and ruts it is alot easier to move around. They each have a place. You just have to remember the 250f is an over weight high powered 125 and it is not going to drag a 180# racer through a sand wash at 90 mph like a geared up 426.

I rode my buddies YZ250F and loved it. I have a 99 YZ400 and his bike turned alot easier and I was jumping pretty all the jumps on his bike that I was on mine. I weigh 210lbs, so I'm probably too big for the bike, but if I weighed less, I would buy one in a second. If you go the WR250F, the power may not be the same even if you change the cam timing because it has a 1mm smaller carb and a wider ratio tranny. I would go the YZF route if I were you.

      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!

      Alright guys, my 04 YZ450f runs fine minus some slight backfires when decelerating (need to adjust fuel screw). The other day when I was done checking my valve clearances I changed the oil and filter and put the bike back on the stand, kicked it a few times without the ignition coil in to get some oil flowing got off and noticed a little drip spot on the ground, it was no bigger than a dime so I thought nothing of it. Started the bike with no issues took it for a quick 10-15 min ride, came back to the garage to find out my whole case was soaked with oil and it started pooling in the low spots on the clutch basket side. I cleaned all the oil off and took it out again for 5 mins to try and see where it was coming from, here are my three possible places but nothing directly leads me to believe it’s any of the three either.
      1. Decompression plug area
      2.  Valve cover gasket leak (not really sure because the amount of oil leaking Looks to be a large amount
      3. Oil tank (bad weld or cracked weld somewhere
      what are you guys thinking?

      Hey guys. I could really use your help diagnosing an issue that came up riding today. Bike is a 2013 YZ450F. Well maintained and haven't had any issues until now. Both the oil and coolant are new and levels are to spec. 
      After riding for about an hour in the sand dunes, I noticed a grinding going on on the right side of the bottom end (from what I could tell). When I looked to see what was going on my kickstarter was vibrating and grinding really loud. This was a different sound than if you engaged the kickstarter while running. It sounded less "clanky" and more "vibrating/grinding" if that makes sense. Grabbing the kickstarter and moving it didn't help the issue.
      When I noticed it, I shut the bike off and gave it a second. Being a few miles deep into the dunes, I had to get it out of there so I started it back up and it seemed fine- no grinding. I headed back to the car and after a few minutes, it came back so I shut it off again, started it back up and nothing. That process happened one or two more times before I made it back to the truck. Seemed to run fine otherwise. 
      Once I got it back to the truck I started it up and tried to pay more attention to what was going on but it wasn't doing it. I did seem to have more of a metal on metal noise coming from the motor. I started and stopped the bike a few times and after the motor stopped there was a distinct metal clank/grinding noise that happened right after the motor shut of for maybe half a second. This doesn't happen every time. 
      I tried doing some research and have seen things that make me think it could be the spring that connects to the kickstarter, or the kickstarter stopper plate- but really I have no idea.
      Seems strange that the issue is off and on.
      Thanks for the help!

      Does anyone know if there is any differences between the 2 radiators? Will the yz450fx radiator bolt on a yz450f? What I am wanting to do is wire up a fan to my 2016 yz450f. I know how I am going to do it I just don’t want to use a “universal” fan kit. What I would like to do is get a 450fx radiator and the direct bolt on Trail Tech fan for that radiator to have a good clean look.
