    No experience with Shorai. I have read mixed, mostly positive comments.

    Personally I always buy Yuasa, though on Wifey's Sherpa we went to a more powerful Yuasa battery than the original spec model due to the strains of cold starting + heated gear. Since batteries keep getting smaller, we got more power that still fit in the same space.

    FWIW - we keep our bikes on Battery Tender Juniors when parked at home. In case you do the same, note that Shorai batteries require different chargers.

    Skierd,

    Might recommend a Motobat(http://motobatt.com/) "MBTZ7S" it has the same dimensions and 6.5 ampH compared to 6 for the Yuasa YTZ7S which is usually a little more costly than the Motobat batteries.http://www.amazon.com/MotoBatt-MBTZ...ie=UTF8&qid=1341065748&sr=1-1&keywords=MBTZ7S vs. http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Dautomotive&field-keywords=Yuasa+YTZ7S for the Yuasa. Besides the Lithium Ion batteries have that aversion to cold (40deg. and lower) problem to work out yet and they cost twice the price of the yuasa. The new Aug. 2012 issue of Motorcyclist has an article on page 84 about the Lithium Ion batteries; but they don't appear to discuss the known problems with them. If you lived in Southern Cal. or desert states I'd say try one, but not Alaska, and I've seen from your RR's that you ride most of the year round.

    +1. This Texas Torture battery test sold me on the MotoBatt, plus the extra two connections are nice for accessories to be hooked up. I put one in my Husky TE610 when the previous battery had a couple cells that just died all of a sudden.

    This thread totally talked me out of the Shorai battery. I might look at Antigravity Lithium Ion battery instead sometime, but we'll see.

    On the other hand, these guys had good success with Shorai:

    The thread about using them in the F800GS seems to point at the bike's charging system as well as the battery. For me, the jury is still far enough out that I'm sticking to old-school chemistry for now. Deka ETX14 for the F800GS and the stock Yuasa for the WRR.

    I have MotoBatts in my WR and my ST1300. They have been great batteries so far.

    Hi guys, I've been away from the WR250R forum for a few months........I've been pre-occupied riding my 300 XCW Dual Sport cheater.......turning my attention back to the WR"290"R ADV bike since the Flying Monkey rally is now on the near term horizon: http://www.advrider.com/forums/showthread.php?t=766096

    The WR250R is now the WR"290"R thanks to the addition of an Athena top end kit......she's also sporting a new set of shoes......threw on some new Warp 9 wheels......


    A few of pics taken this morning:

    I purchased a 2008 with 2700 miles from a fellow Inmate and since the plastic was scratched and gouged up I went another route- Old school,
    Got white plastics from a /10 WRX and the grafix from Wheeling . here is the end result.

    I bought a spare set of Warp9 wheels so I can run street biased tires for my commuting and still swap back to the knobbies
    (the ones that came with the bike where new) We are very happy with how she came out.

    Has anyone with the Warp 9's sets from ebay had any issues with the brake pulsing? my front is. going to measure today and see what the deal is.

    Looks great Crawdaddy! I'll be curious to hear about the MT-43 front. Previously you ran a rear MT-43 with a knobbie front, didn't you?

    That is a great look gloud. Well done.

    I wish Yamaha would offer some other color schemes besides all blue, all the time. White, yellow, and black all look great.

    My favorite:

    I Like it too; it has that bumblebee effect:evil. I think they got rid of it because it identified with Suzuki's color schemes to much.:eek1

    Gloud the white/red looks great, nice bike. You could try swapping the rotor from your other wheel, I think the Wap9's use the stock rotor. That will tell if you the pulse is a warped rotor or something else.

    I've been running them front and rear on the WR for quite a while. Smoooooth on the road/hard pack rails. Time to throw on the gear and head out today!

    What sort of mileage do you get from the MT-43s?

    Look forward to feedback on the 290.

    No, it uses 2 rings. I think there are enough of these installed to demonstrate reliability.

    I wonder about the increase in torque. Some bikes, like High Five's with the 290 are so heavily modded, it is hard to know what a stock bike would be like with the big bore kit, without de-smogging, pipe, power commander, etc.

    Rode a ~175 loop today with friends........the bike/wheels checked out fine......I honesty didn't notice much of a difference in terms of performance/seat of the pants feel........but I've been riding a 300 XCW for 6 months so my perception of what the 250 "used" to feel like may be skewed......wondering if I need to tweak the FMF Fuel programer settings......sems a bit flat down low.....

    All in all it felt good to be on the WR250R again........so smooth......

    I really like those retro graphics too:

    [​IMG]

    BUT..I hate that after each ride on this bike, I have dirty white side panels. Does not matter if I wear pants in boot, or pants over boot...same thing happens. Sure, they clean up nice with a MR Clean magic eraser, but hate to do it everytime I want to have it photo worthy.

    And did someone say EXC??:evil Sadly, I am still getting used to mine and still ride the WRR faster. :huh
