  1. G650GS Discussion
    Hi all, I'm new to biking and maintaining a bike. I own a G650GS Sertao, which feels like the perfect first bike. Obviously I've not been able to ride my bike due to covid-19, but I went to check on my bike after not running it for more than 4 months and the battery is almost dead -- the...

    I need to change my battery with the issues I've been having lately, but it seems to be a tricky one to find the right one. My usual shop sent me a battery with the model details I gave them, but its the wrong size and type :doh:. So far, I've seen that a Yuasa YTX14 is suitable, but does...

    Sad to say, but I have just not managed to get out and about on the bike so far this year. A combination of poor health and even worse weather, the bike has remained in the garage. However, today the sun shone a bit so I put the key in the ignition and pressed the button! It started, but had...

    Hi Some weeks ago there was a thread about electricals and I commented that my battery did not keep its charge beyond a few days. One of the wise old members said it was only a matter of time before it let me down. It did, on Thursday. As luck would have it I was only a short distance from...

    Hi all you expert guys I took the bike off the Optimate this morning to go for a ride as the rain has actually stopped and the sun is shining. This is the first time for about a month. The engine turned over about three times, coughed and spat, (the bike not me!) before calling it a day. I...

    Hi, Another question from the newbie! My 2001 F650GS refused to start today after standing for a couple of weeks unused. It sounded like the battery was low. The lights came on OK but it just didn't have enough juice to turn over the engine enough to get it going. I do not have a battery...

    Hello The battery on my 2005 Dakar has died and is totally done. I was just about to order one when someone told me that you can buy a maintenance free alternative which is same battery, size etc but is sealed and you dont have to check levels etc. Can anyone advise if this is preferable to just...

    Hi, this probably sounds very stupid but is the cigarette lighter on my F650 2000 model an accessory socket ? and can I charge the battery from it ? I want to make sure before I buy the adaptor lead for the Optimate. Otherwise, I'll just use it to light my cigars while I'm waiting in traffic ...

    Can I or can't I use my Optimax 600 charger via the on-board socket to charger the battery when connected? Typically, BMW manual states only suitable chargers may be used i.e. BMW ones :cool:, or else there is a danger of damaging the vehical electronics (the mysterious CANBUS system again!)...

    Can somebody please help with battery problem on my F650GS 05. The bike is used everyday for commuting, with regular trips to France. About 8 months ago the original battery was run flat, after being left for a few days. It would not recharge and so bought a new bog standard battery...

    right, battery not being charged, I was thinking rectifyer, I am however engine illiterate so forgive me if this is a hugely stupid question. But on inspection I notice that next to the water filler there is a black wire bolted to the frame, looks like an earth lead or something only the other...

I have only recently replaced it; (within the last 3-4 weeks) the bike has only been used once in that time short trip her indoors has not had the time to use it.
