Pre-65 Bikes

Does anyone know what weight difference there is between alloy and steel rims? I'm thinking the standard 21/18" trials sizes. Hopefully someone might have some lying about they could weigh! Thanks!

Hi all, recently I have been thinking about buying a pre 65 bike. I ride twinshock at the moment and would like a Tiger Cub bike to occasionally ride some easy routes on. I understand that some started life as a factory trials bike and some were converted from road bikes to trials. I think I’d rather get a factory trials machine. Is there any advantage to either? And is there a definitive way to identify exactly what model the bike is, can you tell from engine/frame numbers? Any help would be much appreciated. Many thanks.

After fitting new clutch, To my Tiger Cub, metal driven plates, friction plates & removing Serco alloy cover plate and reverting back to the original metal one. The clutch was really good dry with the primary cover of just trying it around the garden. Can I run the clutch dry as soon as I put oil in (100ml transmission fluid) it goes back to slipping on kick over etc? or just a drop of oil to lubricate the primary chain. The new clutch is a lot thicker overall and the 1/4 BSF adjusting grub screw is just hanging on the last few threads, so I loctited it until I stripped down again washed it all in petrol, now no slip until I can get a longer grub screw or convert it …

Hi can anyone tell me where i can download info on the removal and replacement of the oil pump on a b44 please

Hi, Can I encourage everybody to go along to the classic trials bike exhibition at Stonleigh at the weekend. I know that Charlie Prescott and Mick Andrews and many others have worked their "thingies" of to make this happen. Our sport during the 60's and 70's was a source of inspiration to many people, standard bikes and parts were modified into successful trials bikes, and many of these bikes will be there at Stonleigh. Look forward to seeing you there. pat.

Hi can anyone advise me which electronic ignition would be the best for a 32a villiers trials engine and the price of the hole unit. Thanks

Hi all, My Norman trials was first registered (in mid 1962) to this dealership in Leeds, who kept hold of it for the first year of its life. Does anyone know anything about the shop itself or its owners? Norman competition bikes were only built to special order by this time, and its a little unusual that it was sold to a dealership so far away from Norman's backyard in Kent, although there is a possibility the bike was assembled by Raleigh/TI in Nottingham after their takeover. Bike was subseqently sold to a Mr. Kirkland in Otley. Norman's probably weren't the most competitive of bikes by the middle of '62, which might explain why the shop had it for a year, or of co…

Hi Guys The exhaust valve rocker spindle on my cub is loose in the head, it will not tighten only rotates. When I run the engine it moves up a down noticeably at the oil feed banjo end. I guess the head hole is worn, does anyone know of a fix or a good engineering company who can sort it. I guess welding and line reaming to size would fix it. Any ideas greatly received.

Hi, Just got around to fitting a Keihin PW22 carb on my cub, I bought it from auto jumble it is jetted 38 idle, 98 main, 2.5 slide. It is far more responsive than than the Anal concentric that was on(pun in10did) , but will not idle correctly keeps 8 stroking with black smoke from exhaust but pick up is superb. Does anyone have any tips, idle jets appear unobtainable this carb was on early Honda twins CD175/200 I believe, also on the TLR seeley Honda. I have yet to try the fuse wire trick. Any help much appreciated.

I have just bought a 1965 Fred Hardy built Tiger Cub to get into Pre 65 trials in addition to the twinshock stuff I'm doing. I have a few questions (I promise I have searched previous threads first): Oil - The bike came with "20w50" written on the tank next to the filler in the top frame tube. This is a custom made (by Fred) frame and I have no idea of oil capacity or what type to use. Various threads here and elsewhere suggest "Never use synthetic", "Always use synthetic" "Only use mineral" etc. I understand that there are three oils (Engine, gear and chain case) I have managed to find some information on capacity for gear and chaincase (half a pint from memory) but a…

Hi , as above my cub has one of Petes clutches .Question is does anybody else run one these with an Armac lightener ?, I can't seem to be able to get the action right ,if I adjust so as the bike will kick start ok this results in there not being enough leverage to disengage properly . Iam having doubts that this type of clutch will work with the said llightener . Any feedback or help would be great . Thanks .

Hi everyone, I am confused by the process of adapting modern internals into a pre-65 type fork leg. I am an engineer by trade, but find it hard to visualise the process. Is anyone out there able to explain the concept? Do you bore out the classic fork bottom? That would weaken it. Do you make special bushes? That would be difficult, as modern fork stanchions tend to be of larger diameter than classic. Do you machine the outside of the modern leg, and somehow fit the entire modern fork within the classic fork bottom? I can only imagine that classic fork legs must be chosen carefully, with larger diameter ones preferable, or modern forks chosen that are close to the d…
