What did you do to your WR today?

4,495 posts in this topic

Put on a Lexx Slip on exhaust, sounds absolutely great. Little bit of a power boost from it. Also installed the Applied racing ais removal kit and tinkered with the carb some, and the bike is 1000x better. Only real issue i have left to solve is that wonderful impeller shaft leak and she should be ready to ride!

Got the new adaptor to fit a newer yz number plate.

What is the adapter and where did you get it?

For my 2004 triple clamps it bolts on the front so u can mount the newer style number plate. If you take the headlight off. I did for racing. It's from applied racing

Rejetted my 2007 WR450F

 

main 162 to 165

pilot 45 to 48

stock needle shimmed with a washer (at most 1 clip position if it had them)

leak jet 60 to 50

fuel screw 2 turns out

o-ring added to accelerator pump arm

 

I also removed the plastic piece under the airbox snorkel (which was previously removed) to open the airbox even more.

 

The bike has a full Pro Circuit Ti-4 exhaust and I'll be installing a quiet insert when it arrives.

 

I ride at 4800 ft to 7000 ft, 30F to 80F. Mostly about 5500 ft and 50F. I do want to ride it in Baja in January, sea level to 2000 and up to 80F(?). Please let me know if I'm off on the jetting. Should I get a NCVS or NFLR needle before putting it back together? Does it need different starter and pilot air jets?

 

I just bought it, my first 4 stroke dirt bike besides dual sports from long ago, and I only rode it once. I found it lacked power in the low to mid range. It has the usual WR mods (throttle stop, grey wire, snorkel). I have been riding 2 stroke 250s for years, and my YZ250 makes more low-mid than this 450.

Took apart the back end to clean and lube all bearings (it had never been done on this bike - ever) and clean up all the aluminum pieces. Should have taken the carb off to clean it as long as I was in there but said "eh." It starts and runs fine as is.

Can you find the Blue in the sea of European bikes ?   At least this ride had a couple 4ts in it - usually it is just my WR and a bunch of 2ts.

 

The snow is gone on the south facing slopes.  A lot of climbing to get up this high.   That grass is slippery where the frost is out.  Pin it and hold on.  Fun times.

 

Everyone is running studs in these pictures, even if you can't see them.

 

Yes it was snowing in the last picture.   We saw sun, snow, sleet and ice pellets several times throughout the day.  Covered a bit under 25 miles.  Great ride.

Man, some of you guys have nice places to ride. Florida (where I am, anyway) really kind of sucks for the most part.

If someone (KRANNIE) could help me with my jetting question in my previous post in this thread, I'd appreciate it.

Installed turn signals, horn and tail/brake light.

 

Next step...head to DMV.

Good luck at the DMV, rear turn signals on motorcycles in California have to be nine inches apart that's why the closest you will ever see are mounted on the outside edges of the license plate.

      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?

      Hello,
      For this summer, I was looking for a project. As a desert/trial, and occasionally single track rider from Southern California, any time of the year works for a build like this.
      I grew up riding two-stroke and after a couple years on four strokes, I want to return to the enduro king. However, KTM and Husky sell their bikes for quite a high price tag.
      So, I have decided I want to take an older two stroke motocross bike i.e. cr250, yz250, etc., and make it the ultimate desert bike for significantly less than a new KTM.
      I am not loyal to one brand, but I have always loved Honda and spent a grand a month ago on all new gear with Honda's name plastered all over it. 
      I know all the mods I want to do the bikes to make them enduro/desert ready: heavy flywheel, 18 inch rear wheel, new exhaust, steering stabilizer, etc.
      What I need help in is I don't know what bikes I can install a wide ratio transmission in. I know yz250 can take a 400 or 426 transmission, but can any other brand?
      I would like to see a cr250 with the gears of a 450x rippin through the desert. I like the steel frame for off road use, and I just need some advice on the best bike for this conversion.
      Thanks
