Just another chance to excel.
Hummmm.....what do you mean nothing will fit on them?

From a few things I've read on here. Unless I totally got it wrong, Cycra's won't fit, GPS mounts won't fit. Apparently it must be an odd thickness bar. I hope I'm wrong. My bar should be in Monday. Keep in mind, it's just my quick reading of a couple posts. I could be completely off base. Sometimes I go through this stuff pretty quick.

All your controls will fit fine. Mounting a GPS is not a problem for most people since there are many different ways to mount them.


You just have to smarter then a 1st grader.


Use these Cycra inner mounts, Zeta and other make them also. I decided to buy Cycra Pro Bend Triple hand guard front mounts P/N# 165502. My Acerbis Super Moto handguard inserts fit in the bars fine

ramz just bought a set of Easton EXP bars for his CRFL and uses them on his WRR also. If you don't believe me ask him...

I see you're all adding some stuff to your bike, when im trying to remove as much weight as i can
She's now 128kg w/o fuel (282 pounds)

Last episode was battery : after seeing Ramz's blog, I inquired about the Shorai batteries.
I've also seen other brands like Antigravity, who advise the 4 cells for a 250cc.

All things considered (cheap way), I decided to make myself a 4 cell A123 battery, like in this video.
http://www.youtube.com/watch?v=UTDctiyUa9E

I bought 4 of these 7.99$ each
http://www.hobbyking.com/hobbyking/s...dproduct=16575

Ended with a 12 ounces unit (instead 88 for stock)




... and the engine cranked up right at first try !

- Don't do that unless you know exactly how and what you're doing ...
- ... and take all responsabilities for risks or damages related on assembly and use of a DIY Lithium battery.
- Otherwise, buy a finished/garanteed product intended for such a use like Shorai, Antigravity, Earth-X, Ballistic ... you will be happy with it.

Very clever....but that prompts a silly question...does the CRF even have a kick starter if your home made battery dies?
My son used those kind of rechargeables in his RC cars, and they were quite unreliable, and very sensitive to the voltage balance between cells.

These are not specifically RC batteries, but LiFE , otherwise called Lithium-Ion that you can find in the DeWalt tools for instance. They are far more reliable and durable than lead batteries.

Altrough I soldered also a balancing plug, this is not needed with this kind of accus.

The RC bateries I mentioned were NiCad, not LiFE or Li-Ion...which I thought were different...I could be wrong.

I have a couple of Park Zone RC toys that use Li Polymer rechargeable batteries that weigh almost nothing, but I think those are a different animal to Li Ion.

Learn here ---> http://batteryuniversity.com/index.p...er_lithium_ion



LiPo are the lighter kind, but cannot be recharged without a suited charger, and are prone to burn if too highly charged/discharged.
Those Li-Ion are more safe (shielded) and accept high charge/discharge, then you can use them not only in remote controlled vehicles.

I suppose the same components i choosed are also used in batteries like this one

Also, $32, plus misc. wire, and connectors, glue gun sticks, maybe an hour and a half labor, compared to Anti Gravity $119.99 for the 4-cell. KRONO, I'm assuming from your location you get a lot of cold weather, as would Ramz in Colorado. From what I've researched, cold conditions are not an ideal use this battery type (Shori & Anti Gravity, & Turntech same type?). Brief ride here today, 42 degrees when I went by the bank around noon.

OK, I'm intrigued, and it's too cold to ride

A123 FAQ: http://hangtimes.com/a123_batteries_for_giants_faq.html

Apparently they are made in Waltham, MA, just like my grandfather's train conductor watch.

While I do fully respect the ingenuity in building your own battery to save a little weight, I for one would never depend on a home made battery on a bike I take into the back country without a kickstart. While it is possible to bump start a FI bike in the perfect conditions, I wouldn't bet my life on all the stars aligning perfectly.
There's far more to a lightweight reliable MC battery than having enough power to crank the engine. The charging and balancing of the battery cells along with other properties not found in consumer single cell batteries will have a lot to do with long term reliability. Your Lithium Ion battery cells are not the same as what's in commercially made powersports batteries, those are LiFePO4, and are quite different. Not to mention all of the cold soldier points your battery has that are subjected to lots of vibration.

A consistent voltage is very important on fuel injected bike as they are very susceptible to any fluctuation, I've spent days trying to track down a bad running engine that would die occasionally, fuel pump/injectors/filters/spark plug/changing gas/etc, turns out to have been a very slightly loose terminal on the battery.
I used to be a factory sponsored RC car racer, and while I'm no engineer I do know I spent a lot of money, effort and time with very precise battery chargers to keep cells very similar to yours operating at full peak. Even then there was a limited life span on Li-Ion batteries that go through peak demand cycles, and forget about it if they are not maintained perfectly.

Don't get me wrong, I think it's in good ADVrider spirit to think outside the box, but I also believe it could be foolish for many folks to slap together something as important as a battery without having a whole lot more data and knowledge of the specific batteries and charging system on the LRP. Having a battery fail could be a matter of life or death, at least for those of us who wander in places far from any help, saving $70 isn't worth the risk to me.

Here's a good thread from a friend of mine who knows a lot more on this subject than I with some very solid info on various MC batteries.

http://advrider.com/forums/showthread.php?t=770364


Another thread on self made battery packs

http://www.advrider.com/forums/showthread.php?t=692962


Search results if you put this code into google for those that want even more info:

site:advrider.com, litium batteries



Despite Joel's findings I still depend on a Shorai in my Husaberg, and probably will put one in the LRP when the OEM battery needs to be replaced. My reasons are mainly not for weight savings though, I'm not a skilled enough rider to feel a couple pound difference, my main thing is capacity and maintenance. When traveling I like to use the bike to charge my camera's and iGadgets, with a Shorai and it's capacity I can charge stuff while in campsite with the bike engine off and not worry about if it will start in the morning. I also travel working for months at a time and don't need to plug in my bikes while I'm away with a Shorai.
I've also traveled in a lot of cold weather with a Shorai, never been stranded. You have to follow their cold weather directions... It's been pretty cold here with frost on the bikes each morning lately, Husa fires right up.
Since reading Joel's findings about the charging system on a BMW effects a Shorai, I check the individual cells in the Shorai on my Husa occasionally, so far that bike seems to keep it charged pretty evenly. All bikes are different and that's my point.
If you do have the proper testing equipment and have done your homework on the cells you're using, please share, I would be most interested knowing more about the charging system on the LRP. With that said, if you just slapped together some random batteries hoping that they will work, let us all know too.
You could be on to something good, maybe I'm just a little too skeptical, only time will tell, reliability would be my first concern, but I go and get LOST often and hate hiking in MC boots. YYMV.
Good luck and keep us posted.

Ordered a set of these bars behind my wife's back - she's going to kill me, but I couldn't resist. I'm pretty sure that between the Brideport mill and the Clausing lathe in my shop I can make a clamp fit on these bars. Of course it would be easier if the Bridgeport CNC mill wasn't down with servo motor issues, but you muddle through these problems as best you can.
