Can anyone supply a servicing guide for a ’58 Birmingham Scott, although my father (and grandfather) was a life long Scott fanatic, as with most kids I never listened (which I now regret !) so while I have basic mechanical knowledge, I’m no expert. My brum Scott runs, but not particularly smoothly, it seems to lack power (maybe I’m expecting too much), so I’d like to give it a good check over but I’m not exactly sure where to start, so I would welcome any advice.
Thanks Jan, yes I have downloaded some articles from the technacalaties web site, but with my limited knowledge I find it hard to determine what information pertains to my Scott and what doesn’t, I guess what I was hoping for was that someone had a copy of an “owners manual” or the like if there was such a thing ?
On my website FlyingSquirrel.nl you will find a downloadable version of The book of the Scotts in the links section. This is for the 1930-s version but I am sure it will contain some usefull info as the Scott motorcycle has basiccally remained the same since then.
Remember, it is a two stroke, it doesn’t have the same low rev. pull like the four stroke. And what fooled me (among many things) was that there are two “eksplotions” every rev, it sounds as it has twice as many revolutions as a fourstroke, which meant that I change gear much too early ( I was accustomed to a BSA A10)
Thanks for the responses, I have owned a “classic” two stroke before, a 1955 BSA Bantam 125, and this seemed as a bike with a quarter of the capacity, to have comparativly better performance, but again maybe I’m expecting too much from a pre-war engine design. I was wondering if there are any owners in the West Yorkshire, Huddersfield/Dewsbury area ? maybe they could take a look and put my mind at rest 🙂
As far as I am aware, 1949, possibly 1950, was the last version of the “Book of the Scott” to be published. This will cover the coil ignition as used on the Brum and also the dynamo as used on the early Brums such as my ’57 version, but not the alternator type. It also gives info on the Dowty forks but only the airdraulic type and not the spring version. The engine, gearbox and clutch are identical through much of the pre-war and post-war range, so any post 1936 Book of the Scott will help. Generally though, Technicalities provides far more useful information.
By the way, check that the pistons are in the right way round. I came across a new Scott owner a couple of years ago at a show, who complained that the bike was gutless, it turned out that the engine had been assembled by the previous owner with the pistons reversed.
Your bike should be able to reach 70+mph with ease, indeed even blind head standard 596’s will run out of revs in 3rd gear when pushed and that will take you off the end of the 80mph speedo on standard gearing… as Jan said you need to give them plenty of beans to get the best from them but when you do that the performance is more than adequate.m The most common probelms are dirty/worn carbs, poor spark or timing, and engines worn/piston rings gummed up/gaskets knackered. If it starts okay the latter are not so likely.
I’m just north of Darlington if that helps, a couple of hours of testing and looking will usually tell you if there is a simple cure or a full rebuild required. You are welcome to call me if you want and I can run through some items on the phone, contact details in link below.
