Title: Bit of learning for today?

Apart from Bill revealing that nylocs aren't infallible, I read on an eBay add that if you have a decompression lever, you don't need a kill switch for the MoT.

Yes I learnt that many years ago from a friend who used to do trials riding in a big way. He used to use his decompression lever to kill his bike. A lovely white and green OSSA 350 MAr..... which I later learned stood for Michael Andrews replica

I had a few different trials bikes and if they didn`t come with a decompressor valve I used to take the head to a trials riders workshop in Great Ayton to get one fitted. They were invaluable going down greasy muddy slopes, also as you say, a great way to kill the motor

Mmmmm, I have neither decompression levers or kill switches on my Jawa's. I always MOT them at the same place - have I just been lucky?

Any bike with an ignition switch wouldn`t need a killswitch , it could of course still have one, the very old trials bikes i have had either had a valve lifter to stop the engine or no tickover. But I have no idea if they are a requirement for mot, could be

I used to do some (very bad) trialling with the Midlands Classic Club and Mick Andrews used to come along from time to time as he is a Derbyshire lad. In the days before compulsory helmets he wore a white flat cap which my son once picked up for him when it fell off! Does that qualify as fame?

I used to joke that his James 250 was a James TY250 as it had certainly benefitted from his years of experience in machine preparation. Unless that is just my way of not feeling so bad that I was crap and he was a genius!

The latter, I too remember Mick floating over stuff that I was totally stuck in. I used to enter (compete is too strong a word) in some of the British Bike Championship rounds and Sammy Miller was just the same on his Ariel. I remember following him on one section which was a stream with a tight turn up a muddy bank then a leaf-strewn steep climb. Miller rode it as if it was a main road. I managed the stream but then just couldn't get up the bank and needed spectator assistance. The climb was just out of the question.

Mind you his Ariel was probably about as heavy as Mick's James....
