I’m newer to Scott lore and at present am considering one in my garage, hopefully for the right reasons and here’s (please) where you as a group of experts come in:
My wife and I tour often on a plunger framed BSA A10 outfit and occasionally when I go it alone it is via a 1925 Sunbeam. My wife would like her own bike to participate and I encourage her as she rides quite well. She’d prefer easier starting than a big OHV single of course and prefers the lazy(er) gait of a twin. Subsequently, I have been offered an early ’30’s Scott “Touring” model of questionable pedigree and incorrect tinware. This seems PERFECT for her to my untrained Scott experience. Our weekend jaunts are about 500 miles round trip and we keep it to 50 mph tops as a fellow in our touring group understandably prefers he not blow his SV BSA up. My Grandfather had a 1928 Scott with a sidecar and used to thrash it, so I remember him saying. Has anyone in this group any objections to a 600cc two stroke twin of stated vintage being ridden to such distance at said speed, 3 times a year? I’d LOVE to hear about the virtues or traps of such an endeavor from the experts. My archival research has biassed me to believe that a Scott’s top gear might be unwinding the bollocks off of such a machine at 45+ miles per hour for extended time. Is this true? Might I “upgrade” the front to a larger sprocket or reduce the rear? I’m sure this has been discussed and tried. Thoughts on touring reliability?
Yours in Horrified Two Stroke Terror and Admiration,
Hi, A complicated question here, and possibly a case of how Scotts are perceived by folk more used to a vintage single cylinder four-stroke machine, and how it sounds at say 50 mph, compared to a Scott ridden at the same speed. A two-stroke engine of course, fires twice as often as a four-stroke, and a twin twice as often as a single, per revolution of the engine. SO….. a Scott engine is firing FOUR TIMES as often as your four-stroke single, assuming similar gearing, so they sound to a vintage four-stroke single man as if they are being thrashed unmercifully, when in fact it is only the magneto and its drive chain that are working very hard, spinning twice as fast, and producing four times as many sparks, as the mag on a four-stroke single !
There is no reason why a typical vintage Scott should be any less reliable than any other machine of its age, provided that you have a good magneto, a well lubricated magneto chain, and a carefully adjusted oil pump, with no leaks from its pipework.
The only other issue might be the radiator, and renewal may be required if there any leaks from the core, an expense to be factored in when buying an incontinent Scott. Apart from all that, just use common sense and a careful inspection before handing over your money. Non-runners that cannot be tested or demonstrated by the vendor are best avoided unless cheap. A bike known to the SOC, and owned by a member/ex-member, would be preferable to a bitsa constructed from garage floor sweepings. If you can post photos of your intended purchase on this site you will soon get some hopefully good responses.
Good luck !
Thanks for the insightful reply! I’d forgotten they have an oil pump. You’d mentioned to make sure the mag chain is looked after and the pump (I’m assuming they are Pilgrim?) is carefully adjusted. Does anyone in the SOC premix or do they oil from the bottom end up? PS someone just sent a YouTube video to me of a skinny teenage girl easily starting a Scott. My wife indeed will be inspired by such a positive result from a wee human weighing less than air. Last year a friend tried to teach her (my wife) to start a Velo Thruxton and it did NOT go well…
Hi, The vast majority of three-speed Scotts have a Pilgrim pump, apart from a brief flirtation with the Best and Lloyd Mark 2 in 1927/early 1928. It is perfectly possible to run a Scott on petroil mix, but the engine MUST be modified to do so, with modern seals instead of the metal-to-metal sealing glands that must have a continual flow of oil to prevent rapid wear/seizure.
😀 😀 😀 Hi Scotty Hayes 😀 😀 I rode my 29 Flyer from Oxford to Inverness with no problems at all!! 😀 😀 Paul Rickards and I did at least 500 plus miles a few years ago on our 1920 two speeders! 😀 😀 Set them up right and dont worrry mate. They are as tough as old boots! 😀 😀 Regards Ted
