Took mine for a MOT, but washed it first, was also surprised it started as it's not been run much this year (only one day out this year).
Rear brake switch wasn't working so failed.....The MOTer had some none oem ones so was going to swap it over, but after unbolting it, it started to work, so he cleaned it, got it working properly and put it all back together.
Passed with no advisories except a verbal one - to get out on the bike more.
G O N N A give Barney's Superbikes of Fort Fareham in Fareham a shout for excellent service.
