Pre-65 Bikes

I'm considering an inline screw on type oil filter for a C15. Should this be on the line feeding the engine or on the return line? Are there any recommendations for filter types or are all remote auto type filters adequate? Do all modern filters have a pressure bypass built into the filters? Thanks!!

Hi, I am carrying out the final assembly of my Tiger Cub and can't find which oil pipe is 'supply' and which oil pipe is 'return' on the bottom of the engine. I am fitting a top tube type oil tank and have put a feed from the return pipe for the rockers. Also what is the general view on fitting an external oil filter to Tiger Cubs? I have one but will get the bike running before I consider fitting it. I intend to change the oil regularly any way, so the only advantage I can see is that it would add another 1/4 litre of oil to the system. The disadvantage being that there are more possible leaking points! Any help would be appreciated, Bruce.

Hello . Could someone suggest what oil to use for the engine and gearbox on my cub, Thanks

HI, I am considering making an alloy oil tank for my C15. It is in a B40 frame (I think) and currently has a bodged together "standard" steel oil tank. I would like to make a narrower tank with space for a re-routed air filter and neater and enclosed electrics. I have searched the forum and found lots of snippets of good advice but wondered if anyone could help me with some "first principles"? What should the minimum advisable capacity be? What is the best return route (can it enter high up or does it have to be a tube running up inside like the standard one?) What diameter tubes should be used at the return junction to cause the right amount of oil to spli…

Most looking at this topic probably appreciate antique and vintage motorcycles.This past weekend I went to Las Vegas to the mid America antique motorcycle auction.Quite a few U.K. buyers because of the strength of the Pound.Here is a link to some images taken there.It will take you to a sub dir,just click on the file names to see the pic. http://allen224.com/vegas

Hi all, My Dad asked me to scan a picture of an old work van he had and on the same page were some pictures of his trials days that I though you may find interesting. I was going to tell you what year but perhaps you might like to guess?

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

There's been a lot of discussion regarding moving the start of the SSDT, most at present, want to stay as is. The start of the Pre 65 Scottish was ALWAYS at the old school, which has now been replaced by allweather football pitches (or something) Not a word, didn't affect the trial or atmostphere as far as I could detect, so the question is - Why would a move (admittely further) make such a differance ? Covered parking might encourage more traders to set up stalls and add to the hussel and bussel which seems to have been missing. Just a thought. Ross

Artie Ratcliffe filming for 'C.H Wood' of Bradford,the footage was used on the 'Six from the Scottish Duke video' riding up The Devils Staircase. It was also used to make a promotional film for CASTROL oils. Incidentally this was the same bike he won the Scott Trial on in 1957,and secured 3rd place in the SSDT in 1958.

hi Guys Hi Big "J". Was flicking through copies of O.R.R. last night looking for a picture that I knew I had seen in one of the copies, came across the story of "Pathfinder Pollock" in volume 81/83. Reading through the article,the conections with this part of Scotland began showing them selves again. My parents met at work in the Northern Aluminium Company Factory in Banbury, now Alcan. Turned the page and there was the picture with MST on again. The picture of Ted Usher looked familiar,knew I had seen it before in the bookI had been given for Best Newcomer" in a local trial in 1962. The book Max King's "Trials Riding". Found the picture on page 127, turned out t…

I have in my possesion a C15 that I bought in bits (and I mean bits!).I obtained it from an ex BSA employee.The bike had passed through the hands of a number BSA employees before him.The chap I bought it off trialed it in the early to mid sixties.However,he used to ride it to work and whilst doing so had an altercation with a car which resulted in,amongst other things,a bent frame.This of course required a strip down for repairs and while the engine was out it was completely dismantled,Alpha Bearings did the crank in readiness for the rebuild.The frame repair didn't go well however and because of this he lost interest and never rebuilt the motor.Basically the bike stayed …

OK, I'm refering to Big John. He knows all there is to know about the history of this great sport. Here it is. Who's bike is this?

Which way is the little oil pump cover/ sump plate supposed to be installed on a 1960 C15? The documentation from BSA does not say but a couple of their diagrams suggest that the deep part goes toward the front. However, I have a rebuild article that shows it installed toward the rear.

My air filter assembly has a potential leak near the front. See the picture. Am I missing something? Should there be some sort of cage?

Hi Guys Finally i got OSSA Mar forks for my BSA C15 project. I have couple of questions, > There is oil leak from screw on fork leg. I tried to tighten it , but its thread is gone , how to fix it ? > What is easiest way to hook OSSA forks to C15 ? . Should I use C15 ball bearing race to OSSA yokes. or should i use C15 yokes ? and OSSA forks legs . I prefer to use OSSA yokes if possible , they seem more suitable to me. I am attaching pictures .. please advise. Thanks in advance Cheers Talha

I cant find the website for Faber Frames. I was thinking of an 'Otter' frame for my cub Has the address changed? had a long look at Duncan Mcdonalds cub today at a trial does he make them commercially?

I have acquired an Otter (Faber) framed B40 with Betor rear units. They measure up at 13.4 inches between bush centres. The bike seems low at the back and could do with more ground clearance. I disconnected the rear units and jacked the bike up under the bash plate and it looks better with about 14.75 inches between the bush mounts, giving about 12.5 inches of ground clearance. Any suggestions please? Sherpatensing.

Has anyone a picture of a completed Otter framed Cub or has had a ride on one.
