Pre-65 Bikes

What filter are you using on your amal MK1 622 on Cubs Vinnie

I recently purchased a cub to convert into trials trim. I am trying to decide what is the best route to go with for the front end. The bike I have has the heavyweight front end on it. I have read about putting modern internals into the heavyweight forks. I think this may be the way I would like to go with the bike so it looks period correct anyhow. Does anybody have any idea of which parts I neeed to source to make this conversion or a idea how to do it. I have a very good machinist down the street so maching down the legs should not be a problem. Maybe there is someone in the USA doing this conversion? Cheers matt

Hello all, Just joined the pre65 brigade after purchasing an otter framed B40. Is there a service manual available that could give me information such as oil types/quantities, servicing tips etc? The bike is in good condition but needs a few sessions in the 'Cosmetic department' and a good checking over...any help would be appreciated. Thanks in advance, Mark.

hi i am busy converting a road c15 to trials was wondering if i should fit standered length rear shocks or should they be longer, my concern would be lifting the rear end to high and making it look really stupid cheers

The "project" is slowly coming on, far too slowly to tell the truth, and i am now looking for some front mudguard stays. Now in the "good old days" you just went down to your local trials shop and sorted through the mudguard stays they had on the shelf and found a set that fitted or were close enough to be made to fit. Those halcyon day are long gone. Nobody seems to stock anything nowadays just "will order it for you". thats ok i suppose if you are wanting std bits for a std bike but when building a pre 65 "special" it just aint that easy. The bike has Norton Commando sliders and i was thinking of trying eithe TL125 or TY175 stays as they look sort of what i am looking…

Anyone have the final positions from the 06 Sammy Miller Series?

does anyone do a rear sub frame or complete light weight slimline frame for royal enfeilds, or more importantly indian enfeilds????? i am more than happy with the mods i have done allready, but did not want to start fabricating a whole rear end if one is available..

hi there this is my first post, fairly new to this site, finding it very interesting, anyway just bought a competition ex mod c15 b40 frame with a year date 1965 to replace my road framed altered c15 1961 frame ,with a c15t engine fitted trials bike .it as cub or late bantam hubs fitted, having trouble with rear wheel seems like spindle needs more length maybe inch each side .do any body do a different size spindle . think ive sorted front end just need to use b25 bearing races with my original front end?any info would be helpfull cheers

Nearly there with the Cub have had it running but it is not right. It is fitted with the Del-Orto carb but to start it needs the throttle open with the choke on, when the choke is released the engine dies. Can any one tell me have you had to change to any different jet sizes etc in these carbs or alter anything, also what jets, cutaway etc did your carb come with. Thank you in advance for any help.

looking at the ht on ebay could you ride it as is, and be competitive in pre 65 trials?

A few of us are heading up to the wood at Youlgreave tomorrow morning, Sunday 12th. (Where Peak Classics have their next event.. about 1/4 mile north of the village opposite the junction for Middleton) for an hour or two of practice so if anyone fancies coming along we'll be there from about 11.30 Andyrew

Some time ago i managed to buy a pretty rough made up bike but as i was only after the Earl's and engine so out came the dosh. Anyway im trying to hunt down the correct DMW frame to compliment the fork's,late 50's i gather. Does anyone have any idea if these frame's are still up for grab's,or put me in contact with any DMW people. cheer's.

Looking for a few suggestions re the gearing for the James project. It's still in bits just bigger bits So as i havent run it yet i will be having to get some sprockets ordered from Talon. If you run a Greeves or James, Sprite etc what gearing do you use? I am using a std crank sprocket as the smaller ones need to have the crankcases modifying to get it to fit so really down to the gearbox and rear sprocket. I know it will need fine tuning and possible adjusting once i get it up and running, the B40 was the same just fitted a smaller rear sprocket to that as it was too low geared, just like to get it nearish as i cant aford to "waste" a rear sprocket by getting one t…

So FINALLY got me James frame in the shed Now i need to paint it Dont want to powder coat as i will need to modify, you know how it is, adding brackets taking away etc etc. Stove enameling is out too for the same reason. Wanted something i could brush paint so it is easy to touch up the rock damage thats the problem with living in Derbyshire. Also easy to repaint an area that gets damaged due to welding / modifying etc. Tried smoothrite in the past but the bonding qualities are hit and miss plus it seems to chip off at the first sign of a rock or tree interface moment so what does the panel recommend? Must be easy to brush on, cheap cos i'm now broke a…

Hi: I own this Greeves bike, but the sprockets obviously are not correct as the bike is too fast in 1st gear. Somebody knows the correct sprockets? and maybe where to find them in the internet? It is really a pre-65 bike or not??????? Thank you

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?

Most people use a mineral 20/50 in the gearbox casing. Has anybody tried a modern synthetic or semi-synthetic bike oil suitable for wet clutches . I am particularly concerned about the effect on the cork friction rings between the steel plates. What quantities are people using. Have heard anything from .5 to a full pint. Any comments.

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…
