What did you do to your WR today?

Today I installed an FMF Megabomb and Q4 on my bike and also cut some custom graphics out of extras from my graphics kit that I couldn't use and spruced up my headlight housing a little to match the rest of the bike. It came out looking pretty decent; I'll upload some pics tomorrow. The pipe sounds awesome and I would not want it any louder - I'd say it's just right - a bit louder than stock with GYTR insert, and you get that good 4 stroke "crack" when you blip the throttle. I didn't get a real ride with it yet, but did race up and down the street a couple of times and the difference in power and quicker rev is pretty noticeable. I'm definitely happy with it.

I also cleaned my air filter and cleaned/lubed the chain, but that stuff isn't quite as cool as a pipe and graphics.

Next up for the bike is a set of Fasst Flexx bars.

Rode it In untracked powder.

Put on the new Dunlop AT81 rear tire. Ran it a 4 psi with my TuBliss system and it worked GREAT today. Rode everything from tight twisty first gear single track up and down some real steep stuff to wide open rocky truck trails to quad trails with nice berms built up. Man, I love new tires! Only time will tell if it will resist punctures as well as the old D739 AT.

Here are a few pictures from putting the pipe on and making some number plate graphics yesterday.

Did some more planning on my snow bike kit and looked at it abunch.

My '12 got new white plastic today. I haven't yet decided if I like both front and rear fenders yet or not. I do like the polisport plastic though.

New Boyesen water pump, Devol radiator guards ( not thrilled with these ) , Tusk hi-pressure radiator cap ,

still2smokin-My riding partner has the same radiator guards on his '06 YZ450F. I went with Works Connection guards, they fit great, look good, and don't increase the width at the radiator shrounds. The Devol guards appear more sturdy though. My friend has dumped his YZ many times on the rocky trails we ride with no damage to the radiators, although the shrouds were thrashed.

You can barely see the WC guard just under the shroud in this picture, but there's no protection for the lower part of the radiators.

I'm considering some major engine work on my WR, stage 1 HotCams, 478cc big bore kit, GYT-R clutch and the Boyesen H2O pump. BTW thanks for the info on the updated headlight.

RockerWR450-The FMF system really adds to your WR, and the white/graphics look great. Have you re jetted yet, my WR was popping and back firing on decal. I ended up with:

Main jet: 175

Pilot Jet: 55

PAJ: stock

Leak Jet: stock

Starter Jet: stock

Fuel screw (turns out): 2 (Works Connection adj. fuel screw)

Needle Model/Clip position: GYT-R 7 grooves, clip in middle position (needle came with Yamaha AIS removal/de-restricting kit)

700" ASL, currently 35F

Ride-n-Hard-The white plastic looks good on your WR, the FX graphic on the fender really sets it off. I went with white fenders on my '06 also.

This should move a lot more water.

I would like to know if that water pump makes a different.

Thanks a lot man - I'm really happy with the way it came out looking.  I'm no test rider, but right now, I can't imagine the bike running any better, either.  It starts easily cold or hot, has no bog or hesitation whatsoever from off-idle on up, and does not seem to have any fat or lean spots through the powerband.  I'm at about 4000' MSL and the temps when I ride right now are around 50 deg F.  My current set up is:

Main: 170

Pilot: 48 (I think...I just pulled it to check when I re-jetted and wrote it down at home)

Leak: 45 (and I have my accelerator pump linkage safety wired together)

PAJ: stock

Starter: stock

Fuel screw: 1.75 or 2 turns, I forget (tweaked it with the tachometer)

Needle: GYTR, third groove from the top

 

I've got a JD Jetting kit that I ordered from RMATV, but all that's in there that I could really use is the red and blue needles...but since I'm running great in both hot and cold weather with the GYTR needle and have a few extra jet sizes laying around anyway, I think I'm going to return the kit - $75 is pretty steep just for a couple of needles and a few different main/pilot jets.  Anybody have any advice on whether those needles alone are really worth that? 

Rocker-A lot of guys swear by those JDJetting kits, but if you don't need it, why keep it? Big difference in our jetting set ups, different year WRs, altitude and temp. I guess. I'm sure I'll have to adjust my needle when the temp. warms up.

I just moved to Sand Cyn from Valencia. And I just moved my WR over. 

vixjim-Sand Cyn is still a great place to live, (in L.A. county).  When I was a kid we rode our dirt bikes all over. You could follow the train tracks north all the way to the Antelope Valley, south to to Newhall.  I used to ride down to "Dick Allen Yamaha" (now Santa Clarita Motorsports) for parts and to stare at the new bikes!  Indian Dunes was still open, every Wens for practice, every Sat, Sun, for racing.  Rode with Steve McQueen there.  Those were  the "Good Old Days" ,  the only good thing about getting old is the memories.

I cleaned the plug today,lol. I did inspect the air filter and noticed there was a little red sticky substance towards the bottom.Tomorrow i will do a search on how to clean it.Last couple of days it just don't want to start,I tried every which way.I did notice but not sure if it happened before but when i kick it the headlight is dim.I'm guessing its a good thing.I think I will be ordering new brake/clutch levers and bark busters this weekend.

Ufo rear fender with tailight.

Ummm, is that filter oil? I dont want to insult you or anything but thats supposed to be there...... dirty or over oiled air filter can cause hard starting.

I tore the motor out for rebuild today.

Greased my swingarm, linkage and shock bearings. First time doing it on this bike. Bought it new in August 2013 and have 47 hrs on it. Bearings were all still in good shape, but glad it did this. There was barely any grease on them and winter riding here in the soaking wet pacific northwest is not very nice to bearings. Use marine waterproof grease. Should get me to next winter.
