For the past couple of weeks when checking my oil through the view glass I've noticed it's full of bubbles. Is it because it's getting too hot?
Bike temp, idle speed, running & general sound etc all seem fine. It's been serviced at all suzuki advised intervals. It's done 14k and will be ready for another service at 14,500 miles.
Should I be worried? Anyone got any ideas? It doesn't seem to be using any oil - Even after a couple of recent trackdays.
