Pre-65 Bikes

Hi Guy's, Who makes a front and rear trials tyre that (4.00x18 & 2.75x21) that most resembles a Dunlop "universal" trials tyre of yonks ago ?. OR is there still a supply of Dunlop trials universals ? regards to all, Pat.

Can anyone give details for this event, classes etc? When and where?

Found this pic on a USA site, superb workmanship but would need a hinge in the middle for Southern UK trials!!

When checking machine eligibility do scrutineers check the year of manufacture on a V5 document? There are clearly plenty of D14 engined 4 speed Bantams being ridden in Pre 65 trials, when those bikes were originally 1968 or later. So how is this trick pulled off? By putting a later engine in an earlier donor bike, who's V5 is of the appropriate year? I am not so concerned in this post about parts eligibility so much as ensuring the machine's documentation is in order.

Hi guy's , Vale Onslow Villiers Top end V's a standard 32a top end , any info welcome please , weight wise , performance etc ................................... Cheers

I am the owner of a 1959 tiger cub. I wonder if it is a good idea to fit an oil seal in the guide valves to avoid some oil in the chamber combustion...?. There exist some from Norton with similar interior size. It only needs to mechanize the guide. Does anyone have any idea or sugestions about it? Thanks in advance

Anyone run a vello trialer ?? Havn't seen one down here (westcountry) Just wondered how they went in trials trim

If anyone knows of a Velocette MAC trials bile for sale can they please send me a message? I saw one at a vintage trial on Sunday and am interested in getting one.

Well having arrived in Kinlochleven at 3am on friday we've just got back! Two great days of trials half decent weather with rain ( drizzle mostly ) and a fair degree of sunshine. Paul Heys seemed absolutely determined to win , his concentration was a step above most others, Tony Calvert is a very cool customer and he always looked in control. the frist day started with the observers on the first two sections standing on the wrong two sections! ( they were in fact on saturdays sections, ) an impasse looked inevitable until a resolute we've started so this is were we'll observe decsion was made. and so the riders made thier attempts. Mick Grant took a 5 for a tumble as h…

well back from another great weekend and there is much to debate although not the topics most anticipated. the bbc weather forecast through the preceeding week was predicting rain all thursday/friday even the evening tv forecasts had graphic descriptions of the heavy rain/ windy conditions from very early in the week. travelling up on wednesday EVERY diigital traffic notice on the m74/8 had a simple message '' heavy rain forecast for friday throughout scotland'' thursday dawned damp and as we set off on the run rain gear went straight on . the rain continued for the entire day/ evening/night . i wouldnt describe it as heavy just persistant. friday had the rain fallin…

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?

Hi, have just acquired what I assume is a 150 Villiers engine with 55mm bore. The gearbox,primary & flywheel mag seem fine. Unfortunately it's seized, so rather than rebuild this probably underpowered unit, I was wondering if a 197 bottom/top end would fit into the existing gearbox,primary,mag set-up? Thanks in advance...

HI, COULD ANYONE HELP WITH THE LOCATION OF A VILLIERS 32A ENGINE FOR MY JAMES PROJECT I AM HAVING REAL TROUBLE LOCATING ONE CHEERS STU

I have a knackered big end, not sure how bad it is as I’ve not had the engine running (it has about 0.001” – 0.002” play) Do I need to replace the crank pin and con rod or is there an inner & outer race? And can I split the crank with a 5 Tonne press?

Hi everyone Does anyone know the crank oil seal sizes for a 32a engine ?????? ...Thanks in advance

In the process of building a pre 65 two stroke, never did get on that well with 4 strokes, so all i need now is a Villiers 32a or 37a engine. Anybody got one spare? Not bothered about the condition as i expect to have to replace the bearings etc anyway. Just dont want any holes or cracks. So can anybody help?
