What did you do to your WR today?

Created my own battery because I was tired of the OEM crap. I also didn't like other li-ion packs available on the market so I just made my own. This pack is actually 2 indepent batteries packaged as one. So if one dies on the trail all I have to do is switch the quick disconnects and I have a new battery. Ignore the small wires....those are the balance charging leads that I didn't have plugs on yet at the time of the picture. The cranking different between this is stock is very different; with the OEM battery being much more sluggish. Rightfully so since this is double the cranking amps lol. Unfortunately I couldn't easily find small quantities of black shrink tube so I had to settle for green. I didn't quite need 1000 yards of black tubing. I really could have just made a single 4 cell battery that was 1/3 of the size and still had plenty of cranking amps for my WR450. But I wanted a backup battery option.

 

OEM Specs:

130CCA & 6.3 Ah

 

This battery:

8 cell 240CCA & 5.0Ah primary......4 cell 120CCA & 2.5Ah spare. It's around 1.75 lbs, but I haven't measured it yet.

Modified the Unabiker radiator guards. I definitely like them A LOT more than the GYTR guards I had before. The only thing I couldn't understand is the fairing bolt setup for the Unabiker guards. It wants you to use a nut on the radiator side of things to fasten the fairings to the gaurds. Getting a nut in that tight of a space is ridiculous. I then realized I'd have to dick around with that stupid nut setup every time I take the fairings off....hell no. So I took some 6061 aluminum flat bar I had and cut/welded two small squares together. This made a thicker nugget of aluminum that I then welded to the guard in order to bridge the gap between the gaurd and the inside of the fairing.

 

Then I just tapped it for the M6x1.0 bolt. Now it functions just like the OEM louvers with those built-in threaded inserts. Much much easier than trying to mess around around with a bolt & nut.

 

The guard in this picture is for the clutch side. They are not the prettiest welds I've done by a long shot, but they get the job done.

F-ing awesome, i wonder how much power you can put under the seat, my heated grips and led lights drains my battery

I did the Swizz cheese mod and the 79 cent clutch fix and lubed the clutch wire.

Now it's like &%$#@!ing butter - smooth

Will you provide some more details about this, maybe a DIY or some sort of instructions?

It's not as loud as the stock pipe with the baffle removed... doesn't bother me that it's long.

MXJunky removed the manufacturer warning/specification stickers, pushed the bars forward to +1 and verified that the sag was within spec.

Muffler project.

 

Wanting to let the engine breath more, make muffler shorter get performance gain like gytr pro circuit design.

 

Removed 100mm in length.

 

Removed all baffle tubes and plates and replaced with one piece.

 

Basically googled YZ450 muffler and copied the design

 

Cost $45 for exhaust packing and muffler tube, plus getting a friend to alloy weld the case up again.

 

The tip or tail pipe, I cut off the after market $60 "Yamaha upgrade insert" I used the largest internal tube from inside the muffler and after my first ride it was way to loud. Other riders moved over way before I got behind them... Way to loud!

 

I then rolled a perforated sheet from the standard muffler into a cone shape riveted it together, fitted it up into end plat facing forward up inside the baffle tube point end first and got the muffler noise level just right! Power is perfect. 

 

I have GYTR jets fitted as come with the bike from new, standard header pipe. This muffler modification defiantly gives you more response through the rev range.

 

You can control the noise level by making your own end plate inserts. I wouldn't spend money on $600 systems now I am that pleased with the results.  

 

I have attached the YZ450 picture and someones wr450 muffler as a guide.

I got a entire complete yz system for 70 bucks, awaiting delivery

Good score, I couldn't find anything in NZ second hand, looked for a few months. Only option was $450 for GYTR system used. My bike was bought dec 2015 as a "new bike" 09 (first owner) so I wanted to use the exhaust & keep it looking new and not to loud. That said, the exhaust is the first part to look old after a few rides, YZ Muffler would be nice, be good to know how you go with noise? I had a yz250f muffler on my 03 wr250f it was extremely loud (louder than my ktm350sx with a full race pipe).

Check the other thread I just bumped regarding exhausts, I'm going to try to put together a quiet frankenpipe

Does anyone know what the ais removal kit from Yamaha looks like? I don't want to buy the gytr since it is a little expensive and I'm not doing the throttle stop or grey wire mod.

      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?
