Pre-65 Bikes

  1. Started by suggs750,

    Can anyone help????? I purchased a cub frame which was supposedly fitted with a wide swinging arm..... However I'm begining to wonder if it is.... Does anyone know the actual width of a standard cub S/A or a standard cub wide S/A so I can check which I have.... I dont want to modify it if it is a wide one as I'm building a stock looking trial's cub with correct steel tank's fork's etc rather than a trick one...... Pete

    I have just bought a pre 65 BSA C15 that will need some serious reviving to be ridable. Wheel and fork replacement may be easier than working with what is there. The AHRMA rules seem to allow any pre 1975 forks and wheels? Is this correct? Does this mean I could use early 70's Japanese or Spanish forks and wheels? If nothing else, it would allow me to ride while I revive the original parts.

    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?

  4. I've been offered on but have no idea how much there worth or if you can still get parts for them? Any info at the moment would be of help. I'm not looking to do events on it just a bit of fun on the odd Sunday. Cheers

    I have a knackered big end, not sure how bad it is as I’ve not had the engine running (it has about 0.001” – 0.002” play) Do I need to replace the crank pin and con rod or is there an inner & outer race? And can I split the crank with a 5 Tonne press?

    I have an Ariel that since the engine was rebuilt many moons ago run on castrol R. It has to come out for a last minute trial on Sunday and I have no Castrol, will it harm it to just mix whats left in the oil tank with a normal 10/40, or do I need to drain it all out, or does it need to flushed / cleaned throughout before I add another type of OIL. I am sure I read somewhere that it could damage the engine if care wasn t taken when changing from Castrol R. Thanks.

  8. Started by old trials fanatic,

    As some of you know i have finally succumbed and gone over to the dark side and am in the process of building a Bantam. So a few questions as i am a bit confused. 1. Have any of you used the new conrod assemblies, obviously Chinese, from Rex Caunt ? If so what are your experiences ? 2. The popular, and cheap which i like, mod is to swap 2nd and 3rd gear over. Do you find this adequate or do you wish you had spent the extra and fitted a low 2nd gear ? 3. Again the popular mod is to fit the Suzuki 185 piston but i notice that Rex Caunt sells a piston with a correct size gudgeon pin for the Bantam small end so you dont need to make a bush to fit. Has anybody …

    Hi Guy's, This is the frame I have just finished to take our Tiger Cub engine. It is based on the design of Pat Slinn's BSA frame that he built in the competition department in 1964. Here are the pics at last, sorry for the wait. Regards Charlie.

    Hi, I am building up a Bantam trials bike from an engine that seems to be a mix of 3 & 4 speed parts. - So its a 4 speed box, and 175cc top end - but it has the old Wico-Pacy ignition - and it has a clutch basket with 3 friction plates. I've been out for one shake-down ride, and the clutch slipped like crazy. My plan is to get a set of new friction plates, and a set of (6) stronger springs. But I just wanted to check whether this is likely to fix the problem, or does everybody end up having to fit a 4-plate basket. Would the 4 plate basket be a straight swop ? Tony P.

I came across this site when i was looking for some piccys of an Alta Suzuki for a friend who has never heard of one. http://www.eurospares.com/newadd.htm Theres a hell of a lot of stuff on the site but some very interesting old photos that might just be of interest to any trials fans of the trials bikes and personalities of yesteryear. Peter Gaunts BSA side valve trials special for instance Anyway just thought it might be of interest to somebody

    Hi, anyone know which lucas model a 1953/4 redditch 350 bullet would use as my mag has no identity on it but i,m sure its lucas without the dynamo attached. Basically it has a fat blue spark and runs fine with a nice low tickover but when its hot the spark dissapears and re-appears at will and this is rather annoying (also sounds expensive ) . Its an anti-clockwise mag, also when the engine is running you cannot see an sparks on the points at all, is this normal? cheers Dave

    Hi, Originally posted this in the SSDT forum, but I reckon this is where I should have. My brother and I are currently trying to sort out a load of bikes and parts that our parents collected over the years. We've done a bit of digging into a DOT we have and the info suggests it's 1961 works trials rep that was shipped up to Duncan's in Brechin for John Noble to ride in the SSDT. Would anyone on here have access to start lists/results from the early 60s to see if that could be true? Very grateful for any info or help. Thanks in advance Ian In case anyone is interested, here's a (somewhat blurry) pic!

    I'm fitting together a C15 that has a D shaped air filter container. It does not look like the original design included a gasket for the cover but there are lots of little gaps for dirt to get sucked in. Does anyone have a method for sealing the cover?
