Pre-65 Bikes

heres some pics of the bantam a few weeks ago when it was dry haha, no has tank badges and a todd head

I'm seeking opinion on the best options for a Matchless engine. Is there any benefit in using the older 350 bottom half of the engine? It is smaller, lighter, and the smaller flywheels may suit modern sections better. Has anyone tried this with the later shorter con rod, which should give better torque? Or is there a better option?

Have aquired a Triumph Cub trials bike. Engine is 1958 distributor top mounted. Can anyone suggest modifications to make the bike a bit more competitive for entering pre-65 events. Bike has decent forks and alloy rims at present, but standard shocks. Thanks in advance

I need to partly strip a 1963 Distributor C15 engine to check it over , it will be built as a std 250, as soft as possible . I am not up to speed on these only in gaining info in threads I have seen recently. Are there any weak areas to check, I am hoping to get away with top end strip for now , any thing else to check?/ It will be a long term project, just as long as the motor is sound. It kicks over with good compression, supposedly a runner a few years ago. Thanks in advance

Fitting a PVL to my C15 but it doesn't have any instructions. Could anyone please confirm the position of the 4 spacers provided with the kit? 3 are obviously for the stator and one for the rotor. However, if the rotor spacer is fitted to the crankshaft behind the rotor there is hardly any thread protruding. Similarly should the stator spacers be behind or front side of the stator? Thanks.

Just wondered if any other Bantam riders are using a earlier 3 spd engine ? If so what gearing etc and have you had any problems? I use a 4 speed myself but rarely see any 3 speed out there.

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've got a Bantam with replacement front forks/yokes - one of the top oil seals is knackered and I'm trying to identify the make of forks, does anyone know the make or where I can source a replacement seal. See attached photos. Thanks Elliot

I have a C15 with Alpina forks and 13 1/2" shocks. The frame is a 1960 C15S, gooseneck type and I struggle with the lack of ground clearance. It is 2 or 3 inches shorter than a TLR200. I also have a spare, later model, C15C frame. Do these later model competition frames have more ground clearance? How do others deal with this lack of clearance? Probably due to the offset Bultaco forks, it turns pretty well so I'm reluctant to just jack up the back end. Plus, I don't have that much ground clearance myself.

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…

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

At the last trial I rode someone was riding a Firefly with a Villiers engine it was a very tidy machine. I have not seen one before are there many about in or out of use.

Can the cylinder head be removed with engine in frame?

my old tiger cub snatching in 3rd gear rest all find so stripped gearbox down found the inner layshaft bush worn so I ordered one I would need ream new bush any body know size of reamer need cant used adjustable as doing in insult I am getting blind bush puller from ebay to old one out

Pre65 Entry Form 2009 from SSDT Site Vinnie 2009_P65_Form.pdf

working on the latest bike and changing oils etc. Mazzocchi 35 mm forks , what would a good 'starting' grade be and how much in each fork leg? Villiers 37a gearbox oil, what grade and how much and clutch, again what grade and how much? simple when you know as always but when starting from brown sludge anything has to be an improvement!! cheers.

Hi, Guys, Now we have several "Pre 68" Trials teams coming along to the Classic Trials Show, (List and information later) But we would love to have Roy along to complete the Triumph team of the time. Do you know how I can contact him? you can PM me if you like, do your best for me lad's. thanks. Regards Charlie.

Belongs to both Pre-65 and Twinshock this: BJ: Have you seen the HT3 that some chap in France owns? Duckwizard: Nice Cagiva (Merlin) there too. Lotsa 123's see: Good stuff

I was riding (badly )at scarboro trial on sunday and there was a chap riding a 250 triumph called Duncan McDonald who won the clubman B , The frame on his bike (as well as the rest of the bike )looked very trick , i just wondered if anyone knows Duncan or knows the bike as i wondered if the frame was a "stock" item or some kind of fancy aftermarket jobbie
