I have been watching my Christmas pressie DVD of the 63 Scottish and at a minute and nine seconds in there is a London registered Cub with a frame I don't recognise, what appears to be an alloy silencer and suspension that seems to be about ten years or more ahead of its time - let's say it would attract comment if it turned up at some of today's pre'65 trials and probably be rejected.
Many of you will have this DVD and some the event programme. Does anyone know anything about the bike and its rider?
The man from here http://www.msport.uk.com/ often posts on this site, probably knows all there is to know about the 4RT and is not a million miles away from you. I have no connection with Msport by the way.
Exactly. It was years before I could bring myself to use the clutch but nowadays I do and use the brakes in whatever ratio is suited to what I am doing but mainly the front. But it depends on circumstance, for instance what lies at the bottom of the hill? If it is a hop over a log from a very slow pace then you want the forks compressed by front brake use. Or do you want to slide the back a bit? As Scottie said, "Ye cannae beat the Laws o' Physics Cap'n".
A previous owner did a neat job on mine simply by cutting the shaft! As your main objective (apart from the reliability) is to get a light throttle action there is no harm in leaving the shaft present.
Sure it doesnt matter, couldnt remember the bike, wondered if the bsa bit had any significance?
Sorry ND, I misinterpreted your post as being a criticism of a "modded" British bike. It is a Bantam engined machine produced in the 70's - I remember seeing them at the Scottish.
I think you need to consider how you come across on this Beatabeta. Is it reasonable to say that no stop is not working (or is working for that matter) after only one trial? Of course not.
And where were all these unhappy under forties when it came to attending the trials seminars that keep being cancelled due to lack of support?
Yes you have described a sticking clutch. To free up clutch shift to top (5th) gear, pull clutch lever in and rock bike forwards and rearwards. The tyre will grip better in the rearwards direction so concentrate on maximising your effort when moving it rearwards
As previous person said, clutch issue has nothing to do with motor not starting.
If it ran, now it doesn't, ask yourself "what is different?" Usually that is engine flooded with petrol or no petrol getting to combustion zone.
Or, in the case of an Ossa, lack of spark which can come on suddenly (and, alas, permanently).
Actually this first monoshock topic came up in the pub last night and we have all missed something.
Depending on how fussy you are about wording of course. The first production bikes with one rear suspension unit to be ridden in a trial could be the Lambretta team in the 1959 SSDT. But then scooter trials had been taking place for a while before then.
The Vincent has only one shock absorber-the two "shocks" referred to are actually spring boxes,containing just springs. The single shock absorber is a seperate unit fitted centrally,with a spring box either side.
True enough.
There is a body of opinion that considers shock absorber to be the correct term for the normal combined spring and damper unit, and I'm sure some Vincents have been modded to such a (non-standard)set up with two of these, usually Koni if I recall.
Personally I never use the term shock absorber (which was always more of a car term), suspension units being the motorcyle common usage for the damper and spring assembly back in my day. The American "Cycle" felt that the spring was actually what absorbed the shock (with some justification for, as they said, without a spring the hydraulic damper would absorb nothing) and the damper merely controlled the motion of the spring. This would appear to have some logic as, going further back, nobody ever referred to a friction damper as a shock absorber.
Think the Vincent was cantilever, but had 2 shocks side by side to save space.
Indeed so but barred from Twinshock motocross apparently (they can't be scared they would thrash a CZ surely) despite pictorial evidence that they were raced in the day. There's a famous picture of Lindsay King doing a nose landing on a 1000, brave man, in, I think, a Vincent history.
Sounds like a water oil mixing issue. I have not seen in there before. What is all the peeling balck/grey coating? Factory finish or a previous "fix"?
It should not go milky after a couple of minutes. there is an issue somewhere.
Good luck. Some one with knowledge wil be along soon.
I would think that unless you take the side casing off and fully drain the oil then there will be enough contaminated residue to turn the new stuff white (I've had the same). Believe me you don't want to take the side case off if you can avoid it as the sump guard is a job and a half to replace. Put something cheap in it and drain it a couple of times to get rid of the white residue. But you may find the impeller shaft needs replaced if the seal has worn a groove in it.
Just fitted new chain and sprockets to my 315 and there's quite a bit of variation in chain tension on every rotation of the rear wheel. What should I be looking at to fix this?
As it's obviously not chain wear then presumably a badly made sprocket that is slightly eccentric?
Just wondered if anyone can remember a trial being held in the late 70's in the "Glen" public park in dunfermline in the late 70's?
It used the Burn (stream) running through the main part of the park and the park paths and a massive set of steps within the park. It was my first contact with trails and i guess I would be about 8 or 9, it seemed (in my memory) as though it was like a major trial equivalent to a national or international round but was probably just a clubby event.
If anyone can remember it I wouldn't mind knowing the history of it.
cheers
I think I rode that one but can't remember much about it other than it was run on a midweek evening (but I could be wrong) I think as part of the Dunfermline civic week or whatever it's called. I have vague recollections of riding the burn but none of the steps.
I do however have stronger memories of an arena trial held there another year for the same purpose. The organiser no longer has an involvement but I see him occasionally at the SSDT on his BMW.
No doubt B40RT will be on soon with some recollections.
Unless you're going to run it properly and get it up to a good temperature to drive out the condensation then you are better not to bother. You will also probably not be a***d sometimes (too cold/snowy to be standing out doing that?) and if you leave petrol in the carb too long you will find a solid gunge developing which takes a hell of a getting rid of. Take it from me you only let that happen once, I had twin carbs to deal with and it took a few strips and cleans before they were right.
Drain the carb - it's only a screw turn after all.
Gloves? I always buy from Pete Edmondson at the Pre '65. Not the latest colours of course but sensible prices - even better then the mountain bike gear.
I use Putoline Light Gear Oil in my 2004 290. It's described as a synthetic fortified 2 stroke gearbox oil SAE 75W. You should be able to pick some up for around
