What did you do to your WR today?

Remember when you were a kid and had been wearing your winter boots all winter, and then finally in the spring you put your sneakers on for the first time? Your feet felt so light it was like they were floating. Well, I got that feeling today.

Unseasonably warm temperatures lately melted the ice from the roads today, so I removed my ski and popped on my summer tire, and all I can say is WOW! This is the first time that I really rode without spikes and ski.

The bike landed here in February, so the spikes and ski went on right away. That combo weighs 44 pounds, just over double the weight of the front wheel only. For the first few minutes tonight the front end was so light it felt like I had no wheel at all. I had to learn to wheelie all over again.

The warm weather has also richen’d things up, and I was too lazy to change the jetting tonight, so I leaned it out another way. I pulled all of the plates out of the E-pipe on my 400 and slipped it on the 450, un-corked. It didn’t help the jetting at all, but sure sounded sweet. :eek:

The 400 muffler fit? Interesting!

Frost,

When you have time can you give us a report on how well the exhaust from your 400 fit on the new 450. Is that a 07? Thanks, MTR

Sure MTR.

My bike is an 07, and the E pipe is from my 99 WR 400. I was sent the wrong pipe way back when, it was for a 99 YZ. It had taken a long time to arrive, and sending it back and waiting for the proper pipe was out of he question, so I tried it and it fit. Someone had asked me about it on the 400, thought it was short and asked if I had cut it. I didn’t, but I had forgotten that it was the YZ pipe, so maybe that’s why it looked shorter. Since it may be a fit factor I thought I should point that out.

The header pipe on the 400 must be a slightly larger diameter as the E pipe was a bit loose when I slipped it on. I compared the slip on end with the stock pipe, and it looks like the pipes are the same size, but the E pipe gasket was thinner so it had a larger inner diameter. It looked like I could swap the gaskets for a perfect fit, but I didn’t want to risk damaging the stock gasket so I just left it. Although the gasket was a bit loose, the E pipe slides a bit farther up onto the header, near the bend. Slipping onto the bend snugged the fit, no leaks.

The can fit under the side cover, and I bolted it there using the mounting bolt near the seat.

The mid way bolt didn’t line up with the frame, and the pipe looks a bit close to the shock reservoir. Since I’m selling the 400, I think I’ll get the welder in town to modify the pipe for a perfect fit on the 450 – shorten it and relocate the mid mounting nut, and I’ll order a new exhaust gasket so it’ll fit snugly on the header pipe. I’ll also try to get some clearance between the pipe and shock reservoir to prevent overheating.

The reason I took the blocking plate out of the pipe was not to make it louder, but because the stacked plates direct the exhaust sideways and turns my rear fender black. With the plate removed, the exhaust goes straight out the back, and it doesn’t seem much louder, if any. It’s also shorter, and quite a bit shorter than the stocker, and I like the tidy look.

We climbed above freezing now, and my bike is waay rich. Idling along I can use the hot start lever like a trigger throttle. Normal idle is set slow, but pulling the hot start lever increases the idle so much that I can ride on the street in 3rd without touching the throttle. Even though the temp is above freezing, the hoses and cables are still pretty stiff, making it difficult to turn the carb to change the jets, but I have no choice now. Time to lean out, and hope the temp doesn’t take a dive tomorrow.

Drug my '03 out of the shed where it has been sitting for several months in-30 temps with the battery in. I had torn down the carb and installed JD Jetting kit- my first time working on jetting so I wasnt even sure if it would still run. Figured I had probably ruined the battery.

Ignition light came on, hit the starter and she cranked a few times, pulled the choke and she barked to life! Got lucky on me jetting/carb rebuild she runs great. These things are bullet proof!

I removed the plate from off the top of the air box that the snorkel goes through on my 07 wr450 that really opened it up. also drilled a 2" hole in the inner baffle the one before the tail pipe. I read somewhere in here about someone doing this. All the other free mods and jetting was already done and the bike ran great. These two things really made a difference from just before mid clear through to full throttle.Had to go back up to a 48 pilot though. Great free mod . I'm not wasting money on an after market pipe now. Didn't lose anything on the bottom either.

I went to rogers hill today http://raceway.rogershill.co.uk/

and played moto x on my wr , what fun !!

this is such an adaptable bike, it was good to get some good air and open it right up , best laugh I've ever had . I rode a few 4 stroke crossers to , it makes you realise how smooth and adaptable the wr is, the crossers were more responsive though but I held my own and was impressed with myself and the bike :thumbsup:

edit : to say frostbite your new white tank and stuff look awesome!!

nicest lookin wr I've seen for a long time :rolleyes:

Along the lines of "what wins on Sunday sells on Monday" (mine is more "what I liked about others' bikes on the weekend ride and am buying without telling the wife"):

brake snake: three times fallen branches forced me to stop when my brake pedal got jammed beyond belief. I believe I'm the last off-road rider to get one. :thumbsup:

yamalink: until they make Gaernes with stilettos

fastway handguards: I have some on now, but they are mounted differently than the newer models I saw this weekend; my metal twists badly whereas the two guys with (the newer?) Fastways said theirs don't. I presume it's due to their bolt location.

pirelli scorpion pro: had the XT version but it's more of a mud tire so in about an hour I'm mounting the tried-and-true Scorpion pro that has knobs a bit closer.

2008 WR450 street legal and plated. I installed IMS tank, Doug Henry kit, Dual Sport kit, Works Connection Rad Guards, Moose racing handguards and finished all the free mods.

WOW that is nice!!! :rolleyes:

I've wanted to do that to my bike ever since I got it last summer :rolleyes: Some black rims and gold hubs would push it beyond sick :thumbsup:

Was the seat cover part of the Henry kit?

PM Sent.

Thanks

Thanks all, I'm happy with the way it turned out. The black seat cover came with the Doug Henry kit. The headlight is painted with Krylon Fusion. It's held up to a few rides, but it's not what I would call a permanent solution. It's got small LED turn signals front and back. You can see them in the picture if you look close. I'll post some close ups if anyone is interested. It's also got a Boysen Q2. Thanks again

      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
