Pre-65 Bikes

Hi there Following on from my previous topic on gearbox sprocket.... I got a 13T sprocket off Villiers services to replace my 17T with and at the same time decided to change the cork clutch plates for ferrodo. Sent my plates away for exchange, everything arrived - all good..... Disassembly, went OK, everything removed etc fitted 13T gearbox sprocket Reassembly ..... problem.... There is now about 3-4mm lateral play on the splined shaft that the clutch fits on, therefore when the clutch is re- assembled the clutch actuator simply pushes the entire clutch assembly out rather that pushing the pressure plate out against the springs ??? Any idea what could have gone wron…

Hi All. Can anyone point me towards a good starting point for oil capacity and weight for 1960's REH forks? I'm thinking 200cc of 15W per leg. Thanks in advance David

Does anyone know if a pair of B25/B50 forks and Yokes will fit a BSA C15 ? Cheers

Hello everyone, does anybody know where I can source a new headset for my James (55K7) thanks.

Hi, My friend Walter bought a Tiger Cub 200 with the old (original) carb, which does not seem to run well. He would like to mount a new but Pre65 (Scottish) eligible carb, maybe an Amal 622. What do you recommend? Where can I order one already jetted for a 200cc Cub? Plus manifold. What about the heat protection, distance to the cylinder? Otherwise, what about a new Oko 22 flatsilde for clubtrials? Which jetting there? Thanks for some hints. Patrick from Switzerland

Hi Folks, I've recently picked up one of the later Wassell frames (the oil in frame one with the twin front down tubes), and am considering pairing it with a Villiers 9e/32a engine that has been sitting on my bench. My hope would be to use it in some twin shock events, but before I get too carried away with the idea, I wanted to ask if anyone here has any experience of using these frames for trials, either with the original Sachs/Puch engine or converted to something different? While these don't appear to have been a particularly common bike in the early 70's, what is the general opinion on reviving it for twin shock trials? Or is there a good reason why these …

I am seriously contemplating purchasing a frame kit to convert my old and worn out rtl mono into a twinshock. I was wondering whether anybody has a completed bike that I could maybe try, or at least recommend a venue where I could watch one being ridden in a competitive trial. As these kits are quite expensive and I wouldn't like to commit without seeing and trying a finished article and also what problems they encountered during the build. Any help or ideas would be appreciated.

Hi all, I am just about to finish my Armac cub and i was wondering how much they are worth in relation to what i have spent. The bike has the best of everything. Full Armac frame, Alan Whitton engine rebuild to 230cc with all his breathing, clutch, drive sproket etc modifications carried out. 35mm ossa mar forks in T21 heavyweight sliders. Armac tank, yolks, exhaust, airbox. Dellorto 22mm carb, new cables, mudgaurds etc, everything brand new. So, what do you think it would fetch if it was sold? I cant say i've ever seen one for sale!

Hi Guys My first post & I hope it's in the right Forum Can anyone recommend a supplier near to Solihull West Midlands able to rebore my B40 barrel & supply a new piston, ideally at a sensible price. Thank's in advance Cheers - Frank

Toying with building a Bantam Cub. Tiger cub engine in a Bantam frame. I have been offered a Cub engine, it's an early distributor engine, needs a rebuild. What advantage has the later engine got over the early type?? Can they be built to be as good ?? I realise some varying specs are available, I don't want to go over the top. Thanks in advance.

Does anybody know who makes the mick andrews james replicas you see at pre 65 trials

Could anyone out there in bogwheel land, please advise me as to the best modifications to do to my 1961 Bantam D7 frame for trials use. I have seen some really good photographs of frames on the Yorshire Classic web site and would like to add some more ground clearence to my frame by removing the lower footrest portion. I was thinking of adding two bashplate tubes under the cases and replacing the feeble front engine mount, with proper engine plates, cross drilling the downtube and welding in crosstubes for the bolts. Is this an advisable mod, or will it stop me being allowed in some Pre-65 competitions. The bike has B40 A/B type forks with QD spindle, though I dont have a…

The questions keep coming in :-) If when the engine is running the valve lifter lever on the rocker box moves, does it mean that I need to clearance between the lifter and valve? Or to put it another way, when the engine is running should the valve lifter lever on the rocker box move? Thanks

Hi guys (and gals?),does any one know what size amal concentric carb works best on a marcelle barrel (for trials).In the box of bits which it came with was a 930,with a 928/ 2 1/2 slide,is this in the right ball park? Thanks.

Hi chaps, when I bought the Cub (200cc, R cam, largely standard) I was advised that the Cotton PW22 carb went straight on and was positively the bees knees. So I bought one. It doesn't go straight on, I can find nothing on the internet about it and have had no response from the seller. Does anybody know anything about it? Does anybody know where to get a manifold to fit? Thanks chaps.

Does anyone have the part number (or sizes) of the taper roller bearings for converting the tiger cub / Bantam headstocks?

Hi Looking for some links or advice on where to get parts / services etc for restoring my old man's BSA. It was parked in this spot back in '66 and hasn't moved since. Although i've been around and raced bikes since i was 5, i've never had or ridden a trials bike let alone a 45 year old british one! I have to confess right now i've always been more interested in Motocross. However, the more i see his C15 sitting there at rest the more i'm compelled to restore it. I want to re-build this one just as it it is, the objective isn't to make it into some lightweight special, so no replacement forks with modern internals or cheater mods. Just looking to strip it, paint / …
