Pre-65 Bikes

I am putting the final touches to a James am building got it started and there was a intermitant noise comming from the engine and think have found the problem I have fitted the smaller front sprocket and the chain is slightly rubbing the front crank case with the seal I brought all the parts from villiers services and they said I need to use a die grinder to make it fit thats OK, and I mention the play on the clutch hub shaft (9E conversion on 8E gbox) and they told me there is an adjuster behind the gearbox casing where the push rod goes through but cannot find any details apart from the play should be 0.02" just need an idea how to do it also I have to align the fron…

Hello, I just bought a 1955 James Captain, it’s a surprise for my 84 year old Father he had one back in the day, I don’t pick it up til the weekend but I was hoping for some advice on a running issue that the current owner has mentioned, he said it starts easily and rides but won’t rev fully, I’m not that familiar with 2 strokes so thought I’d ask on here for any tips on where to start, thanks Mark.

I have a BSA B40 running tiger cub wheels could anyone please tell me when they do the conversion do they use the B40 chain and sprocket or the tiger cub? It's running a DID428 chain. Many thanks

Hi guys,first D14 build, can you answer what is probally a stupid question.Can I plug the hole in the l/hand inner crankcase where the split pin (no.60-2721) sits.I'm fitting electronic ign. Is it a breather hole/drainer i don't need any more? Sorry for my stupidy,it's not a villiers!!! THe 4 speed g/box was a b***er too! Thanks for help,

my project currently has some 36mm jap forks in that are not really suitable for trials, I am planning to change to bultaco 35mm leading axle forks as I have access to some, my question is what type of yokes? cubs are non parallel with 1.5 degrees in the yokes as standard, but given that I am changing to leading axle forks should I be looking of parallel yokes to compensate for this change or would non parallel ones work without causing issues to trail/rake?

hi got a twin bearing tiger cub crankcase I want to fit a later block oil pump do need to get the case machined or just strait swop

Hello all wonder if you can help. I have just got round to getting my Dad's old B40 out after been sat for 15 years. It doesn't seem to have any spark and I've been told they have electronic ignition is that true? So I'm a bit stumped.

Hi just joined this forum, I’ve a chance on buying a Greeves twinshock , I’ve only a photo with not much description, I want to find out some information before viewing, could anyone give me a rundown on model, engine year etc etc. . Much appreciated. Dave. Attachment included ,looking at the bike what sort of value as it stands.

noting the problem with all the various classes and routes in a modern classic trial why not go back to the system used when i started, we all rode the same sections no different routes, you just got on an rode the event , as a basic novice you struggled but learnt , your first clean was something to celebrate as you progressed to centre level then national trials ,my turning point was finishing a trial without stopping ,i may be an old fashioned sod but at seventy five i am still riding but now on a proper pre 65 outfit , a panther of course, cheers will

Hi All, Hope you are all keeping well, I am struggling to attain a few bits for my DMW MK15 trials bike which i am currently restoring. Would someone be able to guide me where I could post on the forum. As I am in need of a set of steering head bearings. No originals were found as the bike was in bits when I received it and was not then able to get measurements or part number. And I am looking for a complete exhaust for the bike. The frame bore for the bearing is 46mm outer and then chamfered to a depth of 12mm, Then inner bore of the bearing needs to be 32mm. I have been struggling for a few months now but after a show i have been to have been advised to pop…

Can someone advise me what tyres are available in (or around) 3.00-19 and 3.25-19 for my DOT.Insert other media

I've just spotted this HT5 for sale, advertised on the leboncoin site. It's in France, just south of Paris and asking €9900, which is about £9000. Could be of interest to someone, but, alas, not moi.

Hi Im trying to locate and buy a Royal Enfield bullet 4 speed Albion gearbox as fitted to the works bikes. I think the gearbox is the same as they fitted in the early 50’s trials and road bikes, recognisable by the separate (higher up) gear change lever. The bike I have was probably made from a late 50’s road bullet and so is fitted with the later wide gearbox, and I find it unsuitable for trials. If anyone can advise me as to where I might find a gearbox and what I should expect to pay I will be very appreciative.

ok i have a 1963 francis barnet falcon with i think a 197 9e engine. i am concidering building a pre 65 trials frame wise ect do i go drayton or wasp or is there any other choices out there ? any help and advice is welcome be-it engine wheels frames ect

Can someone tell me what is required to fit a 9E clutch on a 6E? Parts and the alterations required?

I've unearthed a Villiers 11e engine from the back of the shed. I've been told it's likely to have come from an invilid car, but wanted to ask if these are any good as the basis for a trials bike? And if so, what are the best frame options?

I am rebuilding point in the side cub engine my original crankshaft has wear on the oil feed side so got another crank off flebay and that one same wear on the shaft where the oil feed is anything to worry about or do I need to split crank buy new shaft

What methods have you lads used to fit c15 yokes to Tiger cub frame, Know this might be boring old hat but could save me hours of messing.

Getting this off my chest. I do not expect any support in my post. I just wanted to say it and share it. I am a returning rider after a long lay off. I rode extensively in the North and mostly Cumbria. I managed to get to Intermediate standard which was hard to do. You had to win a Novice trial. Very hard 'upt North'. Once up a level you could not ride at a lower level. ie, No more Novice events or results. I now live in Suffolk and ride twin shock and Pre 70 bikes. I am 67 years old and ride the white routes. Here is my first gripe, why do those with far greater ability ride white routes? In some trials you ride as Expert and 50/50 but when it suits you ride the wh…

Good morning all. Just waiting for the last few bits to arrive to rebuild the Cub engine. Just going through all the parts and found these four half washers in amongst the gearbox parts. Ive searched this site for an answer before posting to avoid duplicity , as I’m sure I’m not the first to ask this question, “ where do these go” ?, but was unable to find a post covering this. I have two approved Triumph manuals that Ive scoured but cannot find these half washers in any of the gearbox exploded views. Have I got them mixed up and they fit somewhere else? If someone could send me an image ideally I would appreciate it very much. Thanks everyon…
