New cone air filter

Update as asked.
First rip out (with care) the old air box.. takes time bloody S%*T loads of bolts and screws(one of the main reasons for this mod)..
Then cut the rubber carbie boot in half, right where it use to enter the air box. Then you should have something that looks like this,

Then I put it all together, the new filter has a rubber boot itself but that goes inside the larger rubber boot that attaches to the carbie. You could get a slightly larger air filter that could go straight onto the original rubber boot, but remember that the old air box only had a very small opening where the air flowed, and you only have limited room under the seat, so I used (I think) 38mm cone filter.

I first attached the cone filter with a single cable tie, then used electrical tape, then cable tied it again, and lastly used more taped. Now that filter is on tight and no air leak at all.

Then I placed the filter onto the carbie and checked the fitting..

No worries,
Now start to cup up the large half of the air box.
I took the top and insides out with a grinder. It looks pretty crap, so I then used a heat gun to melt the ruff surfaces from the grinder then sanded it down to smooth it out and then used gaffer taper on the inside and outside of the air box. There are several holes from the injection molding when the air box was made that need covering up.

I put this part of the air box back on because it holds the battery in place, protects the air filter from stuff coming off the back wheel and the mud guard also attaches to the back of this air box.
Next I made a coned shaped air filter to go over the new cone air filter, remembering that I don't want too much air flow into the engine from what was engineered with the original air box, and I want CLEAN air for the carbie.

I used a sheet of air filter foam cut it to shape glued the edges together with some bricks to hold it down. Once glue was set, I reversed the filter (inside out) so the seam is on the inside of the new coned filter as you can see above and placed over the filter.

Again cable tie the filter on.

Then put the filter back on the bike.

As you can see it fits fine, and I used some of the filter foam on the breather pipe that use to go into the air box from the top of the engine.
I screwed in the carbie fuel mixture screw right in then out 3 1/2 times.
I put the bike all back together, pushed the bike out of the garage and started it up.
At idle the throttle is more instant and revs up much quicker, I haven't done a road test yet, but when I do I will post more info then.
The main reason for this mod is:
  • Sand got pasts the standard air filter set up
  • I couldn't clean the air box out like my WR450F, it took me an hour just to get the bloody off the bike just to work on this mod (being careful of cause)
Now once the seat is off and just one screw for the left hand side panel/faring and I can now use ONE screw (one the carbie) to take the whole filter assembly off to clean it properly.. makes me very happy..

If you got any questions just ask, but give me some time to do some tests, at the moment the carbie is standard not re-jetted at all, and I have a FMF Q4 pipe on, which is way to loud.. next mod is a custom baffle..
The reason I haven't re-jetted, is when I talked to the Yamaha shop about the pipe the mechanic said that an 2009 model shouldn't need re-jetting with the FMF pipe and it didn't.. go figure.. but we'll see how this air box mod affects the fueling..
Cheers

Obviously that will be hard to accomplish, since the WR has more power than everthing else in it's class, but would the XT be worth considering?
I think the xt250 and the new CFR250L are both worth a look in. My wife's xt250 has a 1" lowing link, slip on pipe and now air filter mod. What u get with the xt250 is a very easy bike to ride with enough power to go wherever you want. I once went over some real slippery bushes and logs that I had to go over to get around a broken down 4x4 on a track for my wife and not an issue with xt250 great usable power, then tired the same on my WR450F and kept slipping with the rear tyre and I'm a good rider but the xt250 has a smoother power delivery and every time I ride the little xt250 I think this is really nice to ride. Just bit small for my height. Put a set of D606 's on and slip on pipe and the bike is transformed.

jckid,

Have you installed a Yamalink and slid the forks on your WRX to lower it? If not, that might be an option for better half.

Sarah

Excuse me for side-tracking the XT thread

Since I'm in the market for a 250 dual sport, I've been watching these threads with great interest but I have to ask owners of the XT250 why this bike over the other options? While I realize the CRF250l is a recent release, why a XT250 over the Honda? (Or a KLR250S for that matter) The price of a new XT just seems out of place for this bike. The Honda, while heavier seems to provide a lot more bike for less money. Now with that said, I do appreciate the XT's stone ax approach to simplicity. Air cooled, screw type valve adjustments, also lower seat height. I'm lost in analysis paralysis on this one. A local dealer has an 2012 XT for asking price of $4000.00 with 1100 miles on it. Still seems disproportionate though with a brand new CRF sitting right next to it going for about $500.00 more.

sometimes, less is more. Fewer headaches down the road with the XT.

Well, I didn't buy mine for me to ride. At 6'6" and 250lbs I don't really fit all that well. I also bought mine used. But havingh said that I will have to do all the maint. and that is nice and easy. Also, my girlfriend was new to bikes so I wanted something a little less daunting. Something she could ride on the road mostly at first, then also be able to put some dot knobbies and get her learning on the dirt. (I think she should have learned on dirt first but she wont so...)

Seat height was my highest priority. My daughter is 5' 4"
Also found a 2009 with 650 miles for $ 2800. Keep looking.

That's a great deal and I buy one like that in a heartbeat if I come across one. There always seems to be a few available until I have some extra cash. Then there's not one to be found.........

I would get the Honda over the Yamaha if price was the same (or if Honda is just few more new ova secondhand) and if the seat height isn't an issue. Because the Honda has a six speed gearbox and just as reliable as the xt. Don't forget for some strange reason the xt near went big like the CRF250L will and getting new parts for the Honda will be easier in the long run.
But in saying that, the xt has a bigger fuel tank and a very good engine that is solid that u should never have issues with if maintained correctly.
If u r already going to outlaying a few thousand $ an extra few hundred isn't a lot over years of owning the bike, getting a lowering link isn't much and if u wait a secondhand Honda should b very cheap. Think what u will use the bike for and what u want from the bike a six speed may be better for more highway use but the lighter five speed Yamaha better for slower off road.
My three cents..

I'm 5'3" and found an '08 at a local shop that had only 1484mi on it. It was used on a farm to run around on - tires weren't even worn hardly. That being said, I don't think they knew what they had: I asked how much and he told me $2000. When I went back the next day the price had gone up to $2400 but they remembered me asking so I got it for the initial $2000. This was back in late 2011. They raised the forks for me a touch and softened the suspension and I'm flat footed on it. Without those 2 little things I was on the balls of my feet. I've ridden the hell out of it and upgraded to a DR650 and now my son rides the hell out of it! It's a very nimble, capable bike but not well suited to riding the hilly roads of the Ozarks. It's underpowered if you want to keep up with the bigger bikes going over stout hills and mountains!

I cracked up when I saw the Coober Pedy sign. I've actually been there doing some Opal noodling. Stationed at the Woomera site back in the 90's.

Well, Sarah Teach's XT250 Serow (Japanese FI model) is still going fine, and why shouldn't it?
Routine oil changes, brake pads and a front sprocket is all I have had to do.
Though there is a task that I want to address, the rear shock glacier bush needs repalcing with a needle roller bearing. So, if you know of a thread on here about changing the bearing type, then pass the link on to me please.....

I did not know which one to get either...I found a dealer that had the Honda, KLR and the XT-250 in stock. After I sat on all three a couple times I liked the XT much beter. To me it was more comfortable for on and off road bike...knowing that on road driving was a primary concern for me.
