Joe85 Posted January 25, 2023 Share Posted January 25, 2023 Annoyingly, over the last few very cold mornings, the bike has been very sluggish to start. OnMonday i had to disconnect all accessories and turn off the heated grips/seat before it started. I park it in a warm carpark at work, and when i start it at the end of the day it fire up fine. Had the same today, however this time i stoped for petrol just near my house and the f**ker just wouldnt start. The battery voltage was down at 12v. I had an Optimate delivered today and its currently recharging the battery, but do you guys think it's a battery or alternator issue?

I don't know and not much help, people have had issues with the batteries, and recommend you check the battery ground to the frame isn't loose 1 Quote Link to comment Share on other sites More sharing options...

I'm no expert but when I picked up the Africa twin the salesman advised to use a trickle charger when not riding for a while and often in the winter. I'm sure your GS is no different to my bike packed with tech which puts strain on the battery, electronic suspension, ancillaries and my datatool tracker won't help matters. Wait till you hook up the optimiser hopefully it will cure the issue 2 Quote Link to comment Share on other sites More sharing options...
billy sugger Posted January 25, 2023 Share Posted January 25, 2023 @Joe85it may be a good idea to try a battery wjth a higher cold cranking amps than your standard one, though it sounds like your starting to get a dodgy cell on your current one so not getting enough amps 1 Quote Link to comment Share on other sites More sharing options...

It concerns me that after a 40 minute ride it was below the required voltage to start. I probably went a week without starting it in the recent snow.

billy sugger Posted January 25, 2023 Share Posted January 25, 2023 The optimate puts out enough to take a good battery up to a max voltage of 14.2 volts, (its higher than what the battery actually is so it can reach a full charge) and your battery should register 13.7 volts fully charged if all 6 cells are functioning correctly Quote Link to comment Share on other sites More sharing options...
onesea Posted January 25, 2023 Share Posted January 25, 2023 If your relying on Optimate to start your bike on cold mornings, particularly a modern fuel injection bike I would be concerned. Time for basic checks, do you get a charging voltage when it's running. Next for me if voltage is up over 14v is a new battery. Quote Link to comment Share on other sites More sharing options...

Well i only put it on tis evening as i bought it thinking the cold weather was impacting the battery. 14.4v is what i normally see while riding the bike, is that bad?

Joe85 Posted January 25, 2023 Share Posted January 25, 2023 (edited) Here’s some pictures. First is the voltage dripping after switching bike off. . Second is turning the bike on (Not the engine, jsut the bike) with the Optimate connected: Third is the bike running on engine (again pretty sluggish to start). Voltage shoots up to 14.4V Fourth is after switching off the engine, and watching the volts just drop away. Eventually dropped to 11.9. Was barely able to get it to turn over again. I've plugged the Optimate back in, and it says the battery is fine and that its conditioning it. I think it's a duff.

Joe85 Posted January 25, 2023 Share Posted January 25, 2023 (edited) Looks to me like the Alternator is doing its job and either something is dragging the battery down as mentioned earlier or its a duff battery. Will have a fiddle tomorrow. Thanks all. Edited January 25, 2023 by Joe85 Quote Link to comment Share on other sites More sharing options...

Thats normal and what my RT shows on the dash while running then with all the heated shit on it might drop to 14.2v which is plenty Sounds like it could be a duff battery as the charging system looks to be working fine When I turn mine on it saps a lot of power while everything starts up and yours will be the same so I would stick the ignition on and wait a few seconds for the system voltage to stabilise then hit the starter 1 Quote Link to comment Share on other sites More sharing options...
bonio Posted January 25, 2023 Share Posted January 25, 2023 The voltages look fine to me - that's what it should be doing. My guess is that the battery's taken a bit of a beating in the cold. Either the Optimate will cheer it up and make it fine again, or else it will keep it hobbling on for a few more weeks before it dies on you when you really need get somewhere on time. 1 Quote Link to comment Share on other sites More sharing options...
bonio Posted January 25, 2023 Share Posted January 25, 2023 ... when I had my GS they were known for being shipped with batteries that would last a year at best. Perhaps not much has changed there. 2 Quote Link to comment Share on other sites More sharing options...
Joe85 Posted January 26, 2023 Share Posted January 26, 2023 Starting to think it might be a starter issue. Starts first time, if i stopt the bike and try to restart it fails to crank. If i fully turn off the bike and turn it back on, it works first time. I unplugged it from the Optimate after a night of conditioning and was able to start it 10 times in a row by turning the bike fully off (Dash off or key out) and then back on again. It's only when i stop the engine and attemtp to restart it (dash stays on) that it faisl to crank. Just gonna have to take it to BMW. 1 Quote Link to comment Share on other sites More sharing options...

Unless it’s a new thing, That might be a design thing/ software issue? Block on restarting if stopped on kills switch? Or anti theft thing? God knows what they are thinking when things are designed. I would still be suspicious of battery if it cannot go a week without the Optimate. Then That’s a personal thing.

Annyoing because you know the next time it's gonna let you down is when you've pulled over for a piss 300miles from home. Quote Link to comment Share on other sites More sharing options...

Trooper74 Posted January 26, 2023 Share Posted January 26, 2023 Screen Buffeting on V-Stroms .... Todays issue. So ..Before cutting the original screen down i found a Powerbronze short screen on the interweb ..... on first ride, a dash along the local motorway the buffet seemed to have disappeared. Today i want for a longer ride, through the Peak District. Not only no buffet but a much quieter and pleasant riding experience .... fantastic bit of kit... 3 Quote Link to comment Share on other sites More sharing options...
Joe85 Posted January 26, 2023 Share Posted January 26, 2023 (edited) Looks like i found thie issue : Loose connection. Looks like movement on the accessory cable has loosened the Grd terminal bolt.

Joe85 Posted January 28, 2023 Share Posted January 28, 2023 Gave it a good wash. Might be less hassle with out chain maintenance but takes twice as long to clean. 6 Quote Link to comment Share on other sites More sharing options...
Bianco2564 Posted January 28, 2023 Share Posted January 28, 2023 Did a few jobs on the 250R. Replaced the tacho bulb that had blown, have to remove the entire fairing to get to the back of the cluster. Lubricated the speedo cable, noise from it is a common fault on this model apparently. Same with rattling from the clutch lever with excessive play. Found a wavy washer just the right size to take out the worst of the free play. Replaced the air filter. Gave it a good clean, it was absolutely minging after using it last Wednesday. 4 Quote Link to comment Share on other sites More sharing options...
