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


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

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.

...

Good luck and keep us posted.
Li-Ion and LiFePo4 are exactly the same ---> check that here at the middle of the page
http://batteryuniversity.com/learn/a...of_lithium_ion
If you want to be fully assured to get "true A123", you can take these
http://www.hobbyking.com/hobbyking/s...ll_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.

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.
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 was in one of those moods, in pain with an attitude... Sometimes I'm kinda twisted I guess...

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

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

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

If you have any issues post them for input.


At least I did end it singing Kumbaya, not with hate...

Over and out.

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.
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...sphate_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.
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!

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.

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.

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.


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.

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.

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.

Honda CRF-250-L Stage One Performance Kit

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
No other mods at the moment
