WR250X

[giant_mtb]

First pair I bought were those style. Couldn't get em to fit properly. Had to go with Moose. They were only like $37.

Really? Interesting.

This is what I ordered

Not sure if yours was different. What was wrong with them?

[giant_mtb]

I dunno, they just weren't the right shape for my bars. Couldn't get em to fit. They were probably just a bad knockoff.  But yeah I only paid like $30 for em.

Well, I just ordered a ton of stuff for the WR.

Once I get those parts in I'm pretty much done with this build, unless something either goes wrong or I break it, or go crazy and do something like a big bore kit.

I still do want to get a dirt wheelset but if I can't, oh well.


Also, I replaced the locknut on the rear brake clevis with a really thin jam nut. That bought me some extra room to lower the pedal. Feels better now but I'll have to go out for a ride to really test it out.

Oh, I also noticed the sight glass was overfilled with oil. I ended up taking about a half a quart out before the level dipped into the sight glass range. The manual says to put in 1.48 quarts. I put in less than 1.5 quarts when I did the oil change and it was still too high and I had to pull a ton out. Either the quart bottles I bought are way off in their markings or the manual is wrong. Other people have had the same issue with the sight glass being reading over filled.

The engine block says "1300cc" stamped on it, which is 1.37 quarts, which is what the manual says is the capacity without replacing the oil filter. Next time I'm just going to fill it till the oil level is in between the two lines on the glass and ride it around and top off as needed.

New part showed up today! Yay for Amazon Sunday deliveries.



IMS 3 gallon tank.

Stock tank and plastics were off in about 30 min, though draining the tank was a pain in the ass. The fuel pump also has to be transferred between the two tanks. Here's a comparison pic side to side:



Installation was pretty straightforward. In fact the hardest part was trying to get the supplied rubber hose onto the charcoal canister crap these CA bikes have. Next weekend I'll be removing that stuff too for extra weight savings (also gets in the way of a lot of skid plates).

It doesn't look terrible installed, though it doesn't look quite as nice as stock either (though nowhere as ugly as that 4.7 gallon tank).



Main downside, other than the looks and the non-locking gas cap, is that the seat fits like complete shit. I knew this going in but it's still a bummer to see.



Now I need to go get another gas container and some gas to fill this thing up.

[Cookie Monster]

Well, I went to the gas station to fill the bike up and got irritated with the charcoal canister crap because it kept twisting the rubber vent hose so I just ended up removing the charcoal stuff anyways.

I just have to get a big enough plug to plug the throttle body. Since it's almost midnight and no stores are open I just shoved a bolt into the end of the hose and electrical taped it.

It'll be fine for tomorrow till I can go get some more rubber plugs.

[Cookie Monster]

Today I plugged the throttle body and also realized that my brake light was constantly on from having the rear brake pedal too low. I maxxed out the light adjustment switch as low as it'd go but the brake light still wouldn't turn off, so I ended up having to raise the brake pedal a little bit.

I also installed this:



It feels amazing. Hard to believe I paid only $30 less for CRG levers when this thing feels so smooth and substantial. Lever pull is so much easier now so I should have less trouble in traffic.

[Cookie Monster]

Gas light came on at just under 130 miles. I can get about 150 miles per tank, then.

Also, the RSC stunt clutch lever is so easy to use. I love it. No more hand pain in heavy traffic.

[Cookie Monster]

Woohoo! New parts came in today! I got the T-Rex frame and axle sliders, which I was expecting, but when I came home today I found a giant box waiting for me. Turns out it was the Seat Concepts seat!

Seat, unfortunately, still fits like shit thanks to the tank.

I had to kind of squish it into place to get the bolts to fit, but whatever, it's fine.



It's a lot more comfortable than the stock one, and I got the taller seat so there's a bit more distance between the seat and pegs now, which feels great. I can still easily flat foot the bike but any taller and it'd start to get uncomfortable, I think.

Comparison between the stock and SC seat:



Also put the sliders on. They're not as nice as the Woodcraft ones I had on the FJ but they will do the job. I just don't like that I'll have to keep taking them off to even adjust the chain.







Hopefully the rest of the parts will show up this weekend.

So I was doing some research - apparently the Power Commander V is much, much, much better than the FMF. The FMF has a button and 8 LED lights to let you add various amounts of fuel in various parts of the power band. The PCV lets you get much more granular and allow you to tune the bike in 100 rpm increments, add or subtract fuel, etc, all on a computer instead of just pushing a button. They also sell a PCV with an ignition module to allow you to change timing for only $15 more.

I already have a dyno tuning session scheduled a couple weeks out so I decided to just get the PCV to have the best chance at getting this bike to run perfectly. I'm done with the intake/exhaust mods so getting the tune just right is all that's remaining. I'm going to hopefully be putting a ton of miles on this bike and don't want it to be running incorrectly and decrease its reliability or engine life in any way. As is it kind of bogs on the highway which has been very irritating trying to figure out with 6 cryptic numbers. The tuner also said that he preferred the PCV to get it tuned exactly right.

Another cool thing (that I might get in the future) is the ability to run a quickshifter. The sensor is another $220 or so but plugs right into the expansion port of the PCV.

Anyways, I'm just trying to complete all the mods on this bike so I can enjoy it. Not really planning on spending more money on any other parts now (except SS brake lines when I need new pads). I've still got some peg sliders, brake lever and gear indicator on the way. Should be here tomorrow.

[SVT_Power]

is the PCV QS only upshift or downshift as well?

[giant_mtb]

Quickshifter?  That's interesting.

[Cookie Monster]

Only upshift I believe since it can't blip for the downshift.

I don't know why I'd need it on this bike, but it's a lot of fun to play with. I rode a CBR1000RR with one and it was awesome.

[giant_mtb]

I think it's more fun to work the throttle.  You can already clutch-less upshift.  Getting the twist of the throttle down pat is half the fun of powershifting, IMO.  If I was drag racing or tracking, I guess it could be useful, but on the street?  Meh.

Granted I didn't even know something like that existed until now, so. 

[MX793]

When I raced MX, I'd just keep the throttle pinned wide-open, pull in the clutch, click into the next gear, and release the clutch.  Granted, on asphalt you have a lot more grip than on dirt so that will result in really jerky shifts and possibly some wheelspin.

With 27 hp it could be the difference between merging onto the highway successfully and getting splattered in a semi's grill.

I feel like that would be pretty rough on the transmission on the street.

[giant_mtb]

I feel ya.  I've got 14.5 air cooled horses, so I know how critical being on the power can be. 

[Cookie Monster]

More parts!

Peg sliders (I can't believe I paid $65 for these )



ASV brake lever:



HealTech gear indicator (because I apparently can't ride without one ):



And I couldn't resist and finally added some stickers to the bike:

[Cookie Monster]

Got the Power Commander in!

The packaging and build of the PCV is very, very nice. Much nicer than the FMF. They even included alcohol wipes and velcro for mounting and rubber plugs to plug up the expansion ports if you're not going to be using them.

I've dug up my cheap Windows laptop and installed the software on it. I've also downloaded a map another guy with a WR made on a dyno and he has a similar setup as me (airbox mods, same air filter, EXUP/AIS delete, etc). Only difference is he has a full FMF exhaust and I have the full Delta exhaust, but I don't think it's going to be an issue running that map for a couple days before I get it tuned next weekend.

[Cookie Monster]

Installed!



Super easy to install. The only thing that took some time was routing the wiring and figuring out where to put the actual box. Dynojet says to zip tie it under the headlight, but since my headlight isn't stock I couldn't do that so I just stuck it on top of the airbox.

I flashed the different map on. Seemed too easy. Hopefully it'll work, but I guess I'll find out on the way to work tomorrow.


Also, check out how many extra plugs the PCV comes with compared to the FMF:

Tune is a bit lean I think, but it's better than when I first got it. There's a bit of backfire on decel in certain gears at a certain RPM. I'm going to ride it this weekend, but I'm not commuting on it next week and I'll get it tuned next weekend so I'm not worried about it.

[Cookie Monster]

240 mile ride today. Was not bad at all. I'm planning on a 500 mile ride in two weeks. The bike should be tuned by then and be good to go!

I'll try and change the oil on Friday right before I head off to the dyno on saturday.

Nice dirt bike.

[Cookie Monster]

Nice dirt bike.

Why thank you sire.

The rear brake pedal feels mushy. Rather than just bleed the brake line or replace pads I just bought stainless steel brake lines, new pads and a rear brake clevis.

Good thing I'm running out of things to do to this bike.

[Eye of the Tiger]

Put a turbo on it?

[Cookie Monster]

Got the bike dyno tuned yesterday.

I wish they had shown me a baseline run with the tune it had, but they said the map was very lean and had too much timing. I also had them install a new spark plug just to make sure it was being tuned on a fresh plug. The old plug looked discolored from being too lean anyway.

I also want to ask them for A/F ratios, but overall the bike feels much stronger and smoother. No more surging issues on the highway, barely any popping (only happens if I slightly crack the throttle while coasting which is to be expected) and in general it feels very quick and responsive. Definitely not cheap (close to $750 for both the PCV and the dyno tuning + spark plug) but well worth it IMO. I'm done with power mods in any case.

Braaaaaaap

What kind of crazy PCV system did you get?

[Cookie Monster]

What kind of crazy PCV system did you get?

http://www.solomotoparts.com/Dynojet-Power-Commander-V-Fuel-and-Ignition-for-WR250R-X-08-14/

Fuel + Ignition was only $15 more than the fuel only programmer so I got the ignition one.

I partly got it to be able to fine tune the map, but I also got it to get the quickshifter in the future.

I'm want to get good at wheelies first before I get the quickshifter. Mainly want it to do multi-gear wheelies, if I ever get to that point.
