    Thanks for the info. I stand corrected. You seem to be spring loaded to the smartass position. Change in meds perhaps? :freaky

    Li-Ion and LiFePo4 are exactly the same ---> check that here at the middle of the page
    http://batteryuniversity.com/learn/article/types_of_lithium_ion
    If you want to be fully assured to get "true A123", you can take these
    http://www.hobbyking.com/hobbyking/..._A123_Systems_26650A_LiFePo4_Cell_w_tabs.html
    That is the one i had already, but they are 12.99$ (when in basket), and some hve proven the 7.99$ are the same.
    You can get them cheaper on Ebay.

    The cells you can get at HobbyKing are genuine A123, not chinese copy or recycled, that's guaranteed, and they wont cheat with that
    That is probably the same cells used in Antigravity batteries.. You can get 1 instead of making your own, if you're not equiped for that work.
    Shorais are different, probably flat cells w/o shield, more prone to puff, leak and burn than the A123, i'm not sure ... but i've seen some issues relative to Shorais here and there on the net that let me suspect ...

    I've been in RC helis and planes for years and tested all this stuff extensively, since Nitro to Lithium via NiCad, NiMh and so on ...
    While LiPos have to be charged at their nominal capacity (1C, 2C now), you may charge a LiFe at 10x (or 10C), if you have enough power supply : 6 min charging before flying again, no more so many batteries nedded, and I went this way with success.
    A123 are good for hundreds of cycles, not like LiPos that are good only for 20-30 3D heli flys.
    From my experience too, they dont need any balancing, even if i always put a balancer plug, because my charger have this functionality.

    Anyway, I'm not the guinea pig of this concept, as there are many articles and videos on YouTube about this :)
    So far, it's working all right. I'll keep you updated if any issue.

    No issue for starting at 0 degree centigrad here.

    That's true these accus weaken when cold, but when used, their temp raise and works better.

    In this case, you just have to crank 2 -3 time to get them warm and start the engine.

    I'd guess I on still my rant on after "lesjive's" aka tirebiter post he made to me. :dunno

    When I read my own posts at times I have a hard time remembering posting what I did... :mully

    I just meant there are many different ways to mount your farkles. :wink: With some thought just about anything is possible. :deal

    Thanks for the reply, sounds like you have some experience with this type of battery in the (expensive and cool helicopter) hobby's of yours. It's amazing how much stuff can carry over from RC to MC, though I don't believe that battery performance under much different conditions translates directly - your life isn't at risk when an RC vehicle fails. :wink:
    From my experience building my own packs for my RC cars, they are pretty reliable but occasionally the soldier points fail or you get a bad cell, but when that happens I just would lose a race, not get stuck in the mountains or deserts somewhere.
    I also disagree that Li-Ion and LiFePo4 are exactly the same. There are many types of lithium based batteries used for different applications.

    http://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery


    Doesn't matter really though, the battery composition debate is pointless in this context, you are willing to increase your risk of battery failure because you can build your own, I'm not willing to take those same risks because of where we ride. Plus I never thought of YouTube as being a place for in depth scientific research and development.
    I see by how you secured the battery to the bike with one little zip-tie it doesn't look like you're doing the same kind of riding we are in the American Southwest, that wouldn't last long in Death Valley or on many of the high speed rough rocky desert trails found here. We all have different styles of riding and needs and there's no wrong or right, and most things MC related are a compromise. I see your battery as a trade of reliability for weight savings. Too many probably's or maybe's in your theories for my taste. That's just my opinion though, and I respect your efforts.
    I wish you the best of luck, I truly hope you get years of trouble free riding with your battery plus the satisfaction of making it yourself.:deal
    I just wouldn't want someone else to duplicate your work without taking into consideration the risks for whatever type of riding they do, as it's not a widespread proven design like other slightly more costly MC specific lightweight options, regardless if someone has posted something similar on Youtube.







    Speaking of Death Valley, I've been getting the LRP ready for her maiden big camping ADVenture we're going on very soon! :freaky

    Hey Lost !

    I will never be far away of civilisation here, as i dont think i'll find a place where unable to see a house or a road, so reliability dosent have the same priority for me, obviously.

    Here twenty km from Geneva

    But runs in the mountains here can be tuff too, altrough speed isnt my main concern, more trial like, and the CRFL can go everywere (almost). I tried a Berg like yours a few days ago, and what a blast !!, But she's too high too powerful for the tricky places i use to go

    To go back to the batteries, its so light that the zip-tie is overkill here, i guess. And for the little weight-saving, if you know a 10kg part to remove, please tell me ;) Little by little is the only way : i already got rid of blinkers, helmet hoder, tail and so on ..

    Drive safe !

    Got some Zeta handguards installed finally, now my hands don't freeze! Thanks to Brett at srmoto.com for those. :freaky

    Went exploring, sorry for the same location for all the pics, I am lazy went it comes to getting my camera out of the backpack, I need to mount it on the tank or something!

    Nice - I see that you have the flatland racing rack (I think) - I was considering it, how was the installation? Did you get the radiator guard too?

    Beautiful place to ride!

    I'm glad you're getting what I'm saying, we all have different priorities on our bike for what works for us. :beer

    I guess I'm also not realizing how light that little thing is, I know a zip-tie would not hold a Shorai in place. :lol3


    Cheers.





    Awesome photos Guerillah, looks like a great place to ride!





    yeah Sugar, it a flatlands rack. Install was easy, well documented instructions and pieces to help drill the holes in the correct place. I took a few photos of the install I'll post up soon.

    So far I like the rack, it will prove to be useful when strapping things down to the tail and is very minimal for when there's nothing back there. Lightweight, nice machine work. What's not to like?
    Got it from the guys at www.srmoto.com who needed some photos for their website and gave me a good deal in trade.

    I'm averaging 50MPG. :cry

    Yesterday I got 109 mile out of a tank, carrying a little extra fuel in a MSR bottle in the new tool tube on the bike I let it run all the way out.... half the miles on a highway @ 70mph, the rest twisty mountain roads and a little gravel. I do have a uncontrollable twitch in my right wrist, a 13T sprocket and aggressive knobby tires though and I'm sure that effects the MPG a little.

    I've ridden with Nancy on the back once, seemed like it would be fine with enough room for us, we're just a little smaller than you. Would get tight if you were trying to carry camping gear too. As long as 70mpg sustained highways speeds weren't needed I don't see why not... 55 mph country road cruising would be fine.

    Thanks. I'd be riding mainly in the hills round Hong Kong and the New Territories. Road and trail. Maybe the odd short highway run 30 miles or so to get where I was planning to ride. No camping gear unless I'm riding solo.

    STAGE ONE PERFORMANCE KIT FOR CRF 250 L


    I recently purchased this kit from http://bestdualsportbikes.com/dual-s...honda-crf250l/.​

    I chose the FMF Q-4 Exhaust and Megabomb Header. The kit also comes with a FMF Fuel Programmer and 13 tooth front sprocket. The fuel box is already programmed from the factory to match this pipe setup, but you can tweak it if necessary.​

    The Exhaust system fit perfectly. I like the fact that the rear side cover can still be installed to cover the exhaust and the turn signals do not have to be relocated. The fuel box plugged in easily as well....the engine fired right up and ran perfectly. With the stock 14 sprocket it was like a different Bike! Lots more acceleration, especially in the higher RPM range. Top end is improved as well. ​

    After installing the 13 tooth sprocket, THE FUN BEGAN! It races through the gears and accelerates strongly. You have passing power in 6th gear and top end is higher. With the 13, the speedo as way off. With my heavy ass and wide body it showed 145+ KPH, but the GPS showed 123+KPH. It does 80 MPH easily and that is good enough for me...I appreciate the improved acceleration. Others say it will go lots faster. Guess it depends on one”s weight, altitude, fuel and other factors. I think with some more air box mods it will do better. The higher revs with the 13 tooth works very well with the FMF design and fuel programmer and provides the most dramatic results.

    I think the 13 tooth is perfect for off road and mountain riding that I do here in Thailand. Some may prefer the 14 for long road trips.​

    I drilled holes in the air box cover and took off the metal filter screen as directed..it did make a positive difference. I have not cut out the top of the air box yet, but will soon. I also have not removed the pare valve. The engine seems to run the same with the 0-2 sensor plugged in or out. The Best Dual Sports bike guy thinks it works better unplugged and I am testing it now to see.​

    ‘Future Man” at Best Dual Sports Bikes is a great guy to purchase from. He responds to E-mails and answers "after purchase" questions. The folks where the Fuel Box is made provide great service as well and I recommend them highly. He also ships USPS and work with you on custom values if you ship internationally which will save you money.​

    I am happy with my set up because it is “bolt on” without having to program something and it works well without major mods like new, cams, larger throttle bodies etc. I wonder sometimes if I should have purchased the FMF Power Core Muffler since it has more power (low end) and is a little less expensive (louder though!). The Q-4 is plenty loud though when the throttle is cracked on and purrs nicely at cruising speed and I think the performance is good.... it just takes higher revs to get it.​

    If there are negatives I guess one would be that I burned a hole through my best jeans the first day! (FMF does not include a heat shield). I was able to modify my old heat shield however, and it looks ok. If you want a fancy one, there are some on E-Bay. Of course, more power means less mileage. With my riding style I dropped 5-6 Kilometers per liter estimated with the stock sprocket....haven’t measured the 13 tooth mileage yet, but it may be close to the same. (Of course, when you have more power, one tends to crank it on more..the fun factor sets in!).​

    I am not a professional, but I do ride lots....so this review is subjective and reflects my honest opinions without any skin in the game.. Riding for me is Fun and this setup makes that Honda CRF 250 L More Fun!

    Before the 13T, doing medium trails and minor pavement was actaully getting around 70mpg.
    Since the 13T, it dropped down a bit, running around 60mpg in last couple of tanks. Don't do much road traveling, have a different bike for that :D
    No other mods at the moment

    Thanks for the report. I enjoy hearing from actual users! Nice to know this purchase makes a difference.

    I have the 13T (installed)

    I have the Q4, (picked up at a discount) not installed as of yet.
    Got the FIP for Christmas from my wife, she purchased it from BDSB, :clap She loves me :D

    Need to order the Megabomb pipe next week from BDSB

    That should complete that portion of the mods.

    If you have the Megabomb header on your bike, have you had any problem with it burning your pants/boots/etc. since there is no heatshield on the pipe? Just wondering as it looks like a lot of pipe riding really close to your leg. Are there any options out there yet for a heatshield for the CRF250L Megabomb header or is it even necessary?

    I just got my lrp 2 weeks ago and so far am loving it! After reading all the posts on this thread i found the decision easy. I do have on question though. Right now i am using the bike mainly for my weekly commute to work he in Los Angeles and as my first bike I am concerned with its handling at freeway speeds. When i get it up between 70 n 80 the front of the bike shakes quite bad. To the point its kinda scary. Was wondering if this is a common attribute for a dual sport bike of this size. Other than that i am more than happy with the bike. Can't wait to get up to the mountains and do some trails. :)

    Yes, it has much to do with the tires and also the suspension. I am new to this too and have been reading on it for some time now. Less aggressive tires help but will not eliminate it + you will loose in the dirt. Mine likes 70 and not much more before it becomes disconcerting. If you want higher speeds with less wobble get more street rated tires and change out the drive sproc:1drinkket to 13 teeth It sounds like.

    Welcome to ADVrider!


    The head shake at speeds is common on a DS bike, and yes what kind of tires and their pressure you have on will effect it. You can change tires and take away from your dirt riding traction, or you can get a Scott's steering damper. The damper will greatly reduce that headshake on the highway and improve the performance off tarmac greatly also. They are not out yet for our LRP's, but should be available any time. No affiliation with Scott's here, just a very happy customer that's been running them for a while on other bikes.

    http://www.scottsonline.com/scotts.php

    Also, if you're looking for folks to get dirty with, check out this thread, Rohwer is a good place to ride and there's usually someone you can hook up with. If you ever make it up near Ventura you can hit me up, I know some neat places to ride.
