    The page on my web site has the physical dimensions for the shindengen as well as the electrical specs

    It comes with a 3 year warranty, so I'm not concerned. But then I do have a history as a battery killer ... :rofl

    There's a few threads here about LiPo-whatever batteries and if I remember correctly the issue was with the VR on the F800. I think mine ('06 twin spark) is fine.

    Iv had the ballistic for about a year now after killing my original battery in my 2011 G650. No issues at all starts every time. Its crazy how light it is.

    I don't remember exactly but when I was looking for a new battery I read something about how it can hold a charge for a year (or something like that) without being charged so no need for trickle when not riding.

    F800 and F650GS have the same VR. It fits many years of the BMW.

    Kainic, thanks, people are now sending me info to add to it here and there so it is becoming a sum of knowledge from quite a few people

    Added more info on the radiator fan today as well as a non bmw source for the dual spark ignition coils, the info came from one of the 650X guys cause they want the info on line when out on the road. Gravelseeker let me know to add his flex oil line as well which I did yesterday.

    Re the VR Joel Wiseman on advrider thread posted that he checked with BMW NA and the very latest BMW VR's have higher output as the other models were also suffering poor battery life. Would still prefer the Shindengen though

    Just received my reworked forks and axel kit from HOH.

    Looks like I will need to fabricate a bracket for the ABS sensor? Anyone know of any source out there?

    I put pics of the TT ABS bracket in the YZ notes I collated and put on line, I seem to recall there was a design for the bracket in the original JDRadman kits but dont remember whether many were made as most were ditching the ABS

    Hey guys I hope this isn't too "spammy" and I'll nuke it if it is but I'm off loading my F650GS Dakar project with Ohlins and Yamaha fork conversion if somebody is interested. I'm basically going to sell this thing for the cost of the accessories so hit me up if your interested.

    You'll need matching triples and you'll have to shave some material off the headlight bracket on the GS. Some people on this thread have used the 48mm forks. What's your reason for wanting to change?

    Have you seen this info on Wayne's page: http://www.f650gs.crossroadz.com.au/ForkUpgrades.html

    So I know a lot of you out there are doing a swap be it WP or the YZ, so I know there are some used post 2003 Dakar forks out there that are in working order. (sorry if this is not the place for this... if not I'll take the bashing with grace and relocate). I have an 03 that just so happens to have been manufactured before the fork upgrade. I'm just looking to swap in some used new style forks for peace of mind. If anybody has some new style Dakar forks floating around I would be interesting in purchasing them! PM if ya got the goods! :clap

    Why the Shindengen VR over the apparently updated BMW VR?

    The shindengen is a FET device, FET are faster more modern switching elements than the stock SCR type VR which should make for better regulation plus run cooler due less internal power consumption in the switching element and the price is lower without the BMW mark up. In addition the use of the connectors on the VR means easier replacement and many of the Japanese bikes use Shindengen VR's so replacements out on the road should be easier to come by.

    The newer FH020 has a higher current capability as well meaning more overhead. I had not heard of a failure in the Shindengen on a GS until last week, one of the Norwegian riders had a FH012 blow on him, He is replacing it with an FH020

    Need a little help from anyone who has done the ABS removal.

    I followed the suggestion found online at WayneC1's site: http://www.f650gs.crossroadz.com.au/Modifications/Forks/ForkNotesYZ.pdf


    Says to "Remove the cover off the ABS main connector and find and clip the following wires as close to the back of the connector as you can:

    Yellow
    White with black trace
    White with brown trace
    Brown with black trace

    Prepare each for soldering and connect :

    Yellow to White with black trace
    White with brown trace to brown with black trace.

    To test, turn the key on and spin the back wheel. You will see your speedometer register the movement. If not, check your connections.
    When completed shrink wrap the solder joints and tuck them back into the connector."

    Here is how I connected them:

    Same part without the rag behind it:

    My speedo still didn't work. Anyone who has done it have any info? Am I doing something wrong or do I need to connect any other wires?

    Could it be a fuse? and if so which one?

    If anyone has the wiring diagram or a link to it that might help too.

    Thanks!

    Might have figured it out. I found this in the FAQ:


    "Member seh750 managed to remove ABS from their bike. After removing the ABS unit itself, they found the speedo did not function. The solution: According to the wiring diagram, the speedo signal goes straight from the ABS to the dash and does not go to the BMS. I figured it out, either my bike is different or the wiring diagram I looked at is different, but swapping pin 1 and pin 3 solved the problem..... Pin 1 and 3 on the ABS connector. Pin 1 (white with black stripe) connects to pin 24 (yellow) and pin 3 (white with brown? stripe) connects to brown/ground (don't recall the pin number). - So yes, you can remove the full ABS system, and using seh750's suggestion, still have the speedo working."


    So then the solution is to connect


    Pin 1 = White w/ Black Stripe to to the Yellow Wire
    Pin 3 = White w. Brown Stripe to the Brown ground (according to the pinout diagram on WayneC1's site it might be 19 or 16)


    I'll have to test that out and see if it works.

    The above matches the pin out info on WayneC1's site too!! Wayne, thanks for collecting such good info!! http://www.f650gs.crossroadz.com.au/BrakesAndABS.html

    Just did my ABS removal and that is the correct match. I had the same issue: it's not white/brown to brown/black but white/brown to brown (ground) wire.

    Are you going to relocate the battery to where the ABS pump was? If so how do you plan to extend the cables?
