I'm new to scootering, and the first MOT is coming up. My bike is used, so I'm a little concerned. I'm sure tyres are good, suspension I'm not so sure about, but these are the big things:I've just put a new battery in, but the headlamp is quite "flickery" when it idles. It picks up fine when I give it a bit of throttle, will this be a problem?I installed a new exhaust mid-July and it was lovely and quiet to start with. I don't ride every day, but a couple of weeks ago, I noticed it was significantly louder than when the new exhaust was put on. How loud is too loud for the MOT?Thanks,Amy
