Amazing machines. We can only thank the pioneering work of their designers for the hassle free, ultra fast bikes we enjoy today. But all that smoke... any idea what the oil/fuel mixture ratio of the two-strokes might be? I'd guess something like 1:10 😆
The Scotts don’t run on pre-mix - they have a separate oil compartment in the fuel tank, and oil is fed into the engine via Pilgrim pump. The pump is adjustable, and owners may tend to set them to provide a generous supply of oil in order to avoid engine seizure. I have a video of my 1930 Flying Squirrel running in my garage, and even with the door open, it’s like a fog in there. I was still experimenting with pump settings at the time. I also remember, around that time, giving it the beans after riding down a longish hill with the twistgrip rolled closed (the pump delivers oil according to the engine speed, regardless of whether the engine is receiving fuel) and encountering a bunch of cyclists coming towards me round the bend. The engine, having built up an excess of oil coming down the hill, cleared its throat, so to speak, and produced a fug worthy of a battleship’s smokescreen. The leader of the group started flapping his hand in front of his face to show disapproval of the thick miasma they were about to encounter, which I thought was a bit harsh, but on reflection, fair.
@@neilfoddering921 Fascinating info! I've thought that kind of "fresh oil" lubrication system was a much newer invention. At least it makes safe to use prolonged engine braking.
@@mottee Scotts had separate oil lubrication from before the First World War. The Pilgrim Pump wasn’t a high-pressure pump, more an adjustable mechanism which meters the oil and delivers it to the engine. There used to be a saying “never follow a Scott”, because of the tendency to produce the odd waft (!) of smoke.
How do the pack so much smoke into those Scott's. Great to watch and thanks for posting it
Glad you liked it :)
great bikes, missed it again this year
🔊Thank you🕺
Brilliant videos 👍. Great bikes n cars too. So well maintained.
Thank you :)
Really enjoyed watching that
Awesome, thank you!
From the plate no NR6632 this bike is from the state of Negeri Sembilan ,Malaysia
Great !! 👍
Thanks ✌️

Real bikers wear boots it's common sense
Reckon the Bloke with the knee pads on his leathers might be a bit optimistic.
Ecologists watch and cry... and that's what I like ;)
