After months of not riding, and having the bike in the garage on a trickle charge for most of those months, I finally had an opportunity to take my 2012 Street Triple R to the mechanic on Saturday for a service - with the aim of riding to work today without fear of any problems due to being parked for so long. Rode to the mechanic and back - started without any trouble at all, ran like a dream. Didn't put it back on charge when I got home on Saturday afternoon, since I figured it would only be 4 days until I took it out again. Got the gear on, brought the bike out, jumped on... *click* ... nothing. Had the engine light come on momentarily, then the oil temperature light, and the bike refused to proceed. Tried turning everything off and on again a couple more times, but still nothing. Battery showed 11.3 volts - I assume this tells me the battery is drained too much to get the starter to turn over - so it's back in the garage on charge again. I think someone told me once that 12v batteries would normally hold about 14v, so maybe the Street needs pretty much that full 14v to bring it to life? I have an rLink GPS tracker/alarm/immobiliser fitted, the manual for which swears it won't cause excessive drain on the battery while in standby mode. While working in the garage over the weekend I switched the bike on a few times to move it around (didn't start the engine), but never kept it on for more than about 10-15 seconds at a time, and wouldn't have moved it more than 5-6 times over the 4 days it was parked in there. Knowing next to nothing about this kind of thing, I call upon the combined knowledge of NR members - does a voltage drop to 11.3v sound reasonable given the GPS tracker and the 5-6 times I switched the bike on to move it, or is there a chance something else is happening that might be draining the battery more than would normally be expected? I'm thinking about disconnecting the GPS tracker for a few days and comparing the battery drain against what happens with it connected, just as a diagnostic experiment... Thanks for any help!
