    That's a good question and I can honestly tell you that in my case I don't know since I did not do a Dyno run before hand - didn't know the shop was there back then.

    What I have learned about Dynotesting is that all dynos are not equal. If I were to take the bike into a different shop it is likely I will end up with different horsepower numbers. But they are pretty good at tuning a bike by making multiple runs on the same dyno with different fuel mapping and configurations. But I suspect the guy running the dyno has a lot to do with it too since as he explained to me there is the 'dyno world' and then there is the 'real world'. To be frank this is what steered me away from the autotune feature on the PC 5 - that and hanging more hardware on the bike that has the opportunity to be broken later.

    Looking back on the changes I can say the best bang for the buck as measured by the butt dyno was the gearing change.

    After that most of the changes were aimed at two things - simplification, weight, and power. I did try a DRD slip-on at one point but I just thought the thing was too loud for what I wanted and then decided to try the old DR650 solution of a GSXR can and midpipe.

    What I can share with you is another WRR owner's dyno results who start out with the basic airbox mod and butt dyno FMF settings (22.1 HP).

    He then added an FMF powerbomb, Q4 and with FMF adjustments and got to 24.5 HP

    After that he removed the airbox door and got it up to 26.8 HP with some additional tweaking.

    These runs were all done on the same dyno at the close to the same temperature - the first run was done on a different day than the last 7 runs.

    Can't really compare these numbers to mine since the dyno equipment is different but it gives you a general idea of what gains can be made.

    I had to jump start my bike yesterday due to a dead battery. I left the key on by accident. Bike didn't roll that easily with clutch in while in 2nd gear, does that mean my lever cable is loose and the lever isn't pulling the clutch plates apart enough? Is that adjusted at the lever? thx

    It's normal clutch drag.
    Happens on a brand-new bike, too.

    Anyone have a way of mounting rear blinkers on bike? I want to keep existing rear fender but the plastic holding the blinker smashed off. I really want to keep the fender. I would love to see a picture of something. Thanks

    It's all about balance, Yin and Yang, push and pull, flush-with-cash and broke, etc. :lol3 My wife keeps me grounded like that too, love that lady!

    I built a new house when I lived in Wyoming and got to build the garage I wanted with enough space for cars, bikes, carpentry work, and included a sink for washing up (well, specifically for beer brewing :evil). I sold that house and moved to Virginia where I now have a falling down 90-year-old farmhouse with a garage/shed that's a bit scary to go into. No power, no lights, non-level concrete, riddled with mice, etc. The house is shite but the land is outstanding and we've about paid it off. The plan is to build a new house, starting with the garage with an apartment above it. We'll live in the apartment while the old house is torn down and the new one is built. My wife is very cool with this, but I don't think she yet suspects that the garage will have a dedicated bay just for motorcycles, a wood stove, and a workshop area including a half bath - toilet and beer brewing sink :deal. I think she'll be OK with all this so long as I keep the bikes out of the bedrooms :rofl.

    Clutch drag is most apparent on cold bikes and is normal. Since the clutch is submerged in oil, and the oil is cold and thicker, the plates stick together and cause drag. As soon as the engine oil gets a little heat, this goes away.

    Next time, keep the bike in N as you start pushing in only pop in 2nd right before you are about to pop the clutch.

    Thanks so much for posting this. To answer MPATCH's comment, well, not everyone has the time nor the access to a dyno.
    We're talking between 2 and 4HP on this tiddler...

    rsteiger - so you've experienced cut out with the FMF nanny too.
    That's one reason I opted to use the Athena module that came with the kit.
    I always had cut-out incidents with the FMF, and disliked it's vague adjustment and info.
    Using the Athena module, the bike started and ran great from the get-go.
    (As I mentioned before, only a slight warm up is required before the Athena settles in.)
    I thought about fiddlin' with the nanny again, but now I'm gonna pass.

    Thanks again for the info.

    Glad to hear you're having fun. I think I'm about to sell my WR250 with the TR big bore. Just not riding it enough. Let me know if you know anyone looking.

    Thanks makes two pairs :) Really nice picture, the two of you seem very happy. Great way to spend time together, I'm guessing that there probably aren't a lot of wives that ride these.

    I know somewhere in this "mega thread" there may be an answer to this but I am not having any luck finding it. Does anyone have any experience and or opinion how one of these bikes would fit/work for a 6'5" 260lb. guy. I am currently riding an F800GS. I do not want to get rid of it just want something little lighter and more nimble with FI. I am looking to get one ASAP. i guess wondering mostly about the power is 28hp enought to haul me and some gear around? Any opinion or personal experience would be great to hear about. Thanks.

    ...my buddy, the one that talked me off a TE610 and into a WR weighs 220+ if that's any indication. The suspension will handle it. The motor will as well.
    Where are you located? I know one that's going on the block in SoCal soon...

    I'm only 6'2" and 202 nekkid. I had to raise the bars a significant amount to be comfortable standing (30mm risers and a little higher bars). It is a very comfortable bike with a Seat Concepts seat installed, the seat to peg distance is very reasonable for taller folks, not "cramped" like the new Honda 250 I sat on.
    As for power, it is great on back roads and off road. You do need to keep it revved up a little, don't dog it. Prepare to be underwhelmed at 55-60 mph on the street. It will quickly run up to & along there all day, but that's where it is happiest to stay. I really like mine and ride it long distances on pavement to get to trails, but its no powerhouse. It's relatively gutless in 5th and 6th, but they are just for cruising. Riding a WRR is an exercise in momentum, shift down & keep it if you've got it. You're not going to roll the throttle at 60 and quickly approach 80 to pass a car like you can on your 800GS. Mine is geared at 14/48, a little lower than stock, and will go 80mph if I can find a long enough straight stretch, but normally it stays around 60, I'm sure it will with some camping gear as well.
    I feel it is a better fit for me (both height and riding style) than the KLR650 it replaced. I would think it would fit you very well as a more off road bike than your 800GS. You should be able to throw it around with ease compared to your 800 as well.
    That's just my $0.02 after having mine & putting about 3000 miles on it over the winter.

    I am in Missouri, the dealer down the road has a brand new one. I prefer to buy new but thanks for the heads up on the used one and all the info. I am hoping they will let me take it for a ride before I decide. Thats a very good point on the distance between peg and top of seat i had planned on measuring that tomorrow when i am there. I have my beamer set up great for my long legs. I wouldnt expect that kinda of power or comfort just dont want to pay 6 grand and be miseable.

    I was looking at KTMs but wow they seem like alot of trouble. Also plating a WR450F and making it more of a dual sport but they seem limited for that. Its hard to find the perefect bike and even harder explaing to my wife why i need 2 lol lol lol .

    ...I concur...for all the bikes available it's hard to find the perfect dualsport.
    Why Yamaha doesn't make a WR450R is beyond me. Better yet, a WR350!

    I'm always tempted when I see a nice EXC400/450 for sale.
    But then I ride the 250 and find out it does everything I'm capable of doing offroad. Like, who am I kidding...big power offroad is great, but it can get away from ya (me).
    That and WTF, all I do is change the oil on this bike and clean the air filter now and then.

    Look for a clean used one...and get 1/3 off the price.

    I bought mine used from a guy who is 6'3" and it fit him fine, apparently, because he put 7,500 miles on it in the year he owned it :eek1. I'm 5'9" and had to put the YamaLink in and lower the shock and forks just so I could feel comfy when stopping on hills or in gravel/dirt (and my other bike is a BMW 1150GS). I drooled over the array of KTMs and decided the higher maintenance and cost (significantly more $$) was too much for how I'd be using this bike; and the KTMs are even taller than the Yamahas. I also looked very hard at plating a WR450 and decided it was more trouble than it's worth given how much true off-road riding I'd be doing with it. The WR450's are a bit taller and I just adore that pull-your-arm-out-of-the-socket power when you roll on the throttle, but the power comes on very differently than it does in the dualsport 250 model. If I still lived in Wyoming with endless open desert to ride in I would have gone for the 450, I think. I've been riding a very long time and have owned a lot of small displacement bikes and the WR is by far the spunkiest of them I've ever owned. I also really like the >26,000 mile valve adjustment interval recommended by Yamaha :super.

    I am really pleased with the WR250R. I couldn't find a dealer that would actually let me ride one before I bought it, hope you have better luck with yours.
