Pre-65 Bikes

Hi. I have decided to build a c15 trials bike. I am fitting a 400.18 rear tyre which is slightly fowling the chain. Could anyone advise me the best way to get some clearance un order to fit a chain guard. Do I move engine mounts etc?. Any advice appreciated

Did the usual google searches - nothing. So, has anybody put an ali barreled cub engine on the scales?

I want to mount my Miller swing arm, but I don't get the old one out of the frame. The spindle is one peace with the busches ( rust ), any Ideas or special tools to dismount it ?

Hi I have brought a tiger cub trials bike as a project I have had it running before I stripe the bike for a frame rebuild. The engine has been in a frame on my bench on refitting it back in the frame I can not get oil too return from the engine when it is running I am sure I have fitted the oil feed pipes correctly any adivce

Hi Has anyone got a good base suggestion for fork oil weight and the amount for Cub heavyweight (earlier internal spring type) forks? Haynes manual says 150ml SAE 30. Cheers Jon

Hi all, is there much of a difference between the pvl and electric world ignitions, is one better at plonking down to nothing without stalling etc. many thanks

The performance of Pre 65 "heavyweights". Not C15's, not Cubs nor Bantams, but 4 stroke 350's, specifically the Enfield Bullets. Had Brit road bikes all my adult life, but my trials background experience is limited to air cooled 250 2 strokes, a Montesa 247 Cota a long time ago and currently a couple of ty250 mono's. Yes, I know they will be heavier, they won't turn as well etc etc. But, for anyone that knows, please tell me about engine performance compared to a 250 air cooled 2 stroke. Will they loft the front wheel over a log or obstacle with ease just on the throttle etc? Similar low to mid range torque to the ty monos (both have full weight flywheels)? Less…

Am thinking of adding a return line oil filter to my Triumph Cub trials bike, any recommendations of a kit or supplier anyone?

I am so very drawn to the Pre 65 bikes class at the moment, the shapes and the nostalgia are just great. My question is why is there a specific demand for pre 65 ? what happened after 65 that people didnt like>?

A friend of mine is selling a 250 BSA in street trim.How much work and money would it take to turn it into a trials mount? Can the frame and engine be used in standard trim?

I am interested in any information or colour photographs for the Francis Barnett Model 92 from 1963 to 1966, in particular I think the frame was Arden Green, does anyone have the current code or know which car manufacturer colour may match?

Just ordered this and have one more question for any one that has used one. Is it as easy as it sounds? Put the rotor on, mount the stator in the middle of the slots (that sets it at 8 degrees BTDC) and adjust that as needed, wire it up and you're done?? Sounds to easy. Also after installing it do you just take the points,advance unit and the backing plate out then put the bolt back in? Thanks in advance! Thom

I'm thinking of building a spare rear wheel for a 1958 T20c, would this have had a standard or wide rear hub? Or could someone please tell me the width of each so I can measure what's in there to get another one the same size.

Retired to France a few years back. Kept my old TES Greeves in the belief that I might one day ride again. Maybe the Talmag. Maybe the Scottish Pre-65. Maybe some classic French trial. Didn't happen though. Sold the bike and reluctantly accepted that my trials-riding days were over. Since then, as one does, I've been trawling the sales ads for interesting pre-65 and twinshock bikes, just out of curiosity. Seems that there are less and less good 'uns available, so more and more must be mothballed in old blokes' (and lassies') garages. And, crikey, how the prices have steadily risen over the last decade or two! Eight grand for a Cub. Ten grand for a 350 CCM. Fifteen grand f…

Hi all I purchased a whole bunch of new bits for the clutch on my Villiers 37A today. The crank seal on the drive side of the crank looked a bit worn so I got a new Viton one . Is it fairly easy to pry the old seal out of the crankcase end? The old seal looks like it is a standard rubber/nitryl type. Is there any special precautions I should be aware of? Thanks in advance David

Has anyone repacked a Drayton Bantam exhaust? Advice appreciated. Cheers

Hi folks. Does anyone know who made the frame for that rather nice and expensive BSA C15 for sale in the adds. Too expensive for me but would like a good frame to build my own.

Hi, I have just finished building my Armac Cub. During running it in I noticed I had a small oil leak from the inner gearbox case. I removed the outer and inner RH cases to re seal it and reassembled everything only to find I couldn't move the kick start or select more than 2 gears. I have now removed the covers again and realized I hadn't put the lobe on the kick start shaft at 6 o'clock which would explain why that was jammed! Before I put the side back on (for the 3rd time!), can someone just clarify what I need to do with the selector plate, selector forks, indexers and gear clusters. I understand the need to position the selector fork guides i…

Hello, I wanted to know the correct procedure for adjusting the clutch on my 1958 Tiger Cub. In a previous post on this forum, I found the following: Release the cable at the handlebar lever Turn the central adjuster in the pressure plate clockwise gently until I feel the clutch arm touch the outer cover. Turn the central adjuster 1/2 turn anti clockwise then tighten the lock nut. This gives around 1/2mm free play. Re fit the cable at the handlebar lever and adjust to suit - again a little bit of slack. I then only tighten the 3 clutch springs enough for their heads to clear the inside of the primary cover, but I check tha…

Hi guys, Can anyone help me with a starting point for the idea compression ratio for a d14 Bantam with a b175 centre plug head. Thanks, Prelit
