Since borrowing Mary’s ZZR400 this last week or so, I noticed a few niggles with it’s running that I’ve been trying to address. Firstly the front brakes were sticking a little and secondly the running has been a bit on the rough, loud and underpowered side, especially at high speed. To tackle these issues I called up on the skills of Tim (‘Scorch’ on LondonBikers.com), who offers a mobile motorcycle repair service.
Tim popped over to went to work on my bike, whilst I was parked up at work myself. Very handy indeed. He quickly set to work on the brakes, found one of the pistons was a bit gunked up and air in the system. In a couple of hours he had the lot stripped down, sorted, new fluid in, bled and working well.
