AS I said AAngus, I only took the bike there on Wednesday and yesterday I took it for a ride as well, so need to wait now until Friday EOD to start the bike again. Will then know whether it was the tracker, but
motoscot were happy and told me there was no current draw. Now it's a waiting game...
Will let everyone know how it panned out, Friday after lunch! Fingers crossed, I know hope it was the tracker (though the BMW dealership garage never did a single test without it). Even better, they wanted £274.50 just to disconnect the tracker and test the current draw. I don't mind paying for a service, but that is a rip-off, clearly, especially after having the bike serviced there and having been charged £70 to fit a new front tyre.
