    Well... that was smart.... I was replying, then shut down my browser forgetting to grab my reply text first! :rolleyes

    So yeah, I purchased my bike already modified, otherwise I think I'da had the wits to leave that part unchanged.

    Good point about the load on the subframe. I expect to delve into emulating your mod. once the battery expires (or the subframe busts!). I'm thinking perhaps to add some tire rubber between the battery case and the frame members, though.

    Didn't mean to underestimate your rock riding Sr. Spud. It's just that with all the beautiful pictures of you riding around that I've seen, none have included rocks thus far. This is the kind of stuff we find ourselves hammering through in these parts:

    Sometimes you have to speed up to keep your body from being shaken to the point of brain jello!
    And sometimes you break your shift shafts off where they exit the case! :eek1

    PS: Pig was a little reluctant to fire up right off the bat, but she did so before running the battery down (woohoo) and got a good warmup.

    !st shakedown ride with my 'full-size' shorai in the stock loc, so far so good.

    Did some gnarly little stream crossings, used to be the trail dipped down to the stream and there was a little drop, recent heavy rains lowered the streambed and left a bit of vert on both sides. If you can't ride it like a trials bike, leave it home!

    The direct replacement, not the one that is smaller that people are putting under the seat.

    Someone on TT just reported theirs died after 2 weeks- could have been a slow drain.

    I'm pleased to report my Shorai battery relocation is still performing superbly after 7,700 miles of riding. :nod

    The Shorai batteries come in two sizes, #1 and #2, Steve. :nod I mounted the smaller, #2 size battery on top of my air box. :deal

    Dave mounted the larger, #1 size battery in his battery box.

    one thing that kinda bothers me about my Shorai battery relocation is that even though the seat goes back on without any problem, I can tell by the indentation in the pads I placed around the battery that there is quite a bit of rider weight directly on the battery.

    Thank you for the information. :nod If you have time, can you post some photos?

    I have now ridden 10,700 miles since my Shorai battery relocation. I'm pleased to report my Shorai battery, and my XR650L, are both working great! :D

    Hey Spud, I want to do this to my DRZ 400 and wanted to know if the Battery Tender Jr is compatible with this type of battery? Is there anything specific I need to know about these batteries regarding placement,care,servicing, stator? That is a beautiful picture. I am envious and really want to check out that riding in Idaho sometime....

    Thank you, Bob. You can learn a lot about charging the Shorai batteries, et cetera, by reading the FAQs page at the Shorai website. :nod

    http://www.shoraipower.com/t-faq.aspx

    The Shorai batteries self discharge at 1/6 the rate of regular, lead-acid batteries. My battery was fully charged, and ready to install when I received it. Also, I have not needed to recharge my battery since I installed it. :D

    Thanks for the link. I will read up on them. Now about that Idaho riding........:freaky
    OK, I read all of the FAQs and my questions have been answered. The stator will charge them just fine, no tender needed, and my Battery Tender Jr from Deltran can be used however they recommend their own balancing type charger which I have found already. Thanks Again

    Hey Spud, Did you order directly from the Shorai website? I prefer to go that route so I can get the best warranty and the freshest battery but when I add it to my cart it doesnt show if its in stock or not?

    I need to order it from a reliable distributor that can verify it is on hand at the time of purchase.

    Thanks for any time spent to reply....

    I owe you a cheeseburger.....Thanks again... My bike has a YTZ10S big battery kit currently and using the biggest 210cca shorai is gonna save me 5.5 lbs over the current setup and no loss in power!!! I am excited to see how the bike feels with 5 lbs removed off the rear subframe.

    Thank you. :nod I have now ridden approximately 18,000 miles since my Shorai battery relocation, and it is still working superbly. :D I have lots of airflow into my carburetor, and my engine makes very good power after this Shorai batter relocation. :nod

    But how?

    I drilled some holes in the under-seat webs and the side 'rails' on the seat and gained a bit of breathing, so how can that not be choked off?

    I've seen stranger, though.

    My carburetor intake gets much more air than the factory bike with the stock air filter and airbox snorkel. :wink: Indeed, my carburetor intake gets as much air as any other XR650L with a Uni air filter and the airbox snorkle removed. :deal My engine starts well, runs well, and makes plenty of power to suit me. :nod Of course, if one wants to maximize air intake, he can always drill more holes.
