What did you do to your WR today?

4,495 posts in this topic

Top end rebuild time.....got the top end apart, poked around to see what was needed...my cam chain was WHIPPED! So bad it scored the cam sprockets...I probably could have gotten away with them (the lobes, etc was perfect), but, well, good exuse for Hot Cams.

So, 2 brand new Hot cam's, FMF PowerCore, rings, cam chain, adjustable fuel screw, new Race Tech back spring with the correct rate for me...gaskets, seals, valve guides...etc..etc....

Now just got to get it back together....I'm expecting a big difference in the bike with the powercore, and cam's....if not, I'll be quite disappointed!

I finally got around to washing it seeing that I didn't have a chance to do it when I got home after my last ride. Now to do an oil change and do the o-ring mod on the carb.

I also routered out the cross bar pad and inlaid my vapor speedo/tach/temp gauge ect. into it.

That's awesome. That looks sweet. i wonder what would happen though if you smoked your face off the pad where the speedo is now. I've done it before, that would be my only worry.

As some of you might know, the WR450F MY2003 had quite a big problem on the Electric Starter, this was solved out in the MY 2004.

I wanted to do the upgrade of the Electric Starter but it would cost to me approx $300 of spareparts (plus shipment expenses, plus my mechanic manpower), then I have decided to save some money and changed only the Electric Starter broken.

In Italy an OEM Electric Starter costs approx $400, so I have adapted a brand new Kimko 150cc scooter Electric Starter (actually my mechanic did) for approx $50, and intalled in my WR.

It works perfectly, better than the original!!!

sdg8569: although i've seen supermoto guys do some pretty fair sized jumps, you're right it's probly the least of your worries. That would be MY main worry though. I think i might take the risk though, it looks awesome. does handlebar vibration bother it any?

CH250 No it seem that the foam in the cross bar pad dampens the vibration so its not a problem. It actualy make it easier to read the gauges due to the extra rise.

My trusty old '99 WR400.

Installed alloy sump guard.

Fitted some comp3 tyres.

Changed all oil and filters.

Fitted a wavey disc and new pads.

Put on some new graphics (the old original yellow ones were starting to look a little ropey :-)

First ride with my ProAction Suspension done. Took my son out for a ride since he insisted on going out. It had rained quite a bit and he wanted to go splash his 50 thru the water. He wasn't lying either! He hit some water that went up the the seat. I couldn't have been a more proud dad :-)

The suspension on the WR is awesome. All the little stuff I dont' even feel anymore and I can actually get airtime now without bottoming. I hit my favorite whoops section and really felt the difference there.

On the down side, the suspension cleared the way for me to see the shortcommings of the WR all choked up. In 3-5 gear, the bike falls flat on it's face in the midrange and won't pull hard at all. I dragraced a YZF450 quad and he beat me. Time to uncork this thing to take full advantage of my suspension. Been looking on ebay for a yz450 stock exhaust or a PMB insert..no luck so far.

Thank you ! One question though, do I need to still get the PMB insert with this or is the OEM YZ450F just as good, or better than putting the PMB insert into my WR pipe?

OK the PMB insert (bigger baffle) is for the stock pipe to free up some flow. It does add performance but probably only about 1/3 the HP that a free flowing muffler will add. http://www.promotobillet.com/catalog/product_info.php/cPath/46_88/products_id/50?osCsid=0dd153482261eb705cdedc12bee3d8e2

With the YZ exhaust you'll need some type of spark arrestor if you intend to ride on public land or on private property in densly wooded areas. Its not so much that these engines spark or belch out fire (unless its jetted super rich), but even hot debris or muffler packing flying out of a muffler can start a fire. PMB makes it easy by making a rivet in spark arrestor for the YZ exhaust.

Another option you have is to buy a replacement cone spark arrestor (usually $20-$50) from another brand of muffler and rig it into the stock YZ muffler. These will be USFS approved however the burden of proof will be on you to prove that it is. Usually a ranger out in the field will do a "stick test" to make sure the stick won't go through the spark arrestor.

Thanks for the input. I've never been checked for a spark arrestor here and I don't ride on public lands. I can always get a spark arrestor later on.

Now onto the AIS removal kit, free mods and JD jet kit. :-)

      So apparently some mx fcr carbs have removable valve seats and some dont. I didnt know this and just thought mine was really stuck in there so i drilled it out. Was going to replace it anyway. But it turns out that i have the model that is not suppose to have the valve seat removed. or so i think. Is anyone aware of this difference between the same carb. Do you know where i can get another valve seat? its off a 2003 yz450f

      Hey all, recently getting into motocross again and bought a used bike from a kid who lacked on the maintenance side of things for the bike. What I have found / believe is happening is oil is leaking out of the cylinder head breather tube. Before going on my first ride with the bike I had a respectable amount of oil right in the middle of the checkered oil marks on the dip sticks. However after about 5 hours riding I checked the oil to find that it was barely even on the dip stick. I know there has been oil leaking out of the breather but could have been caused because an overflow on the oil change from the kid. I mean the bike is 8 years old maybe it is time for some top end work. On that note would a person change out the piston regardless of condition along with the rings? Is it possible the rings are just not positioned right? I would definitely do the valves while I have the bike open anyways.
       
      Any info would be greatly appreciated I just find it odd that it took 5 hours to drain, reading through other posts some guys were having puddles of oil after 20 minuets of running time.

      I live in northwest Virginia (Charlottesville area)  about an hour south of DC, I am not aware of any tracks in the area that are either public (or private but allow people to ride with permission).  Does anyone know of any good tracks in my area?
