Hello all again I'm after some advice. My B40 is running 13t gearbox sprocket and 60t rear but I feel I need a but more speed on the hills. What combination are people running for trials? Many thanks

Evening All During a day of riding on a family friends farm, we all tried to identify a bike which didn't have any clear branding on either frame or engine. All i've got is the description, no photographs as we we're all in the gear, sorry. A schoolboy sized bike, with a racing/mallard green and yellow striped single piece seat and fuel tank (metal fuel tank under fiberglass). The Engine was hung under a single tube down pipe from the head stock The engine itself is a rotary disc valve unit (looks like a 75-125 sized) with a czechoslovakian downdraft carb There is a right hand side rear brake system with crossover bar, similar to Sprite frames as i've seen on the …

Does anybody know anything about this new frame/subframe/swingarm for a Triumph Tiger Cub from a company called Armac Design - I saw it in a classic motorcycle mag a few months ago. It seems to be excluded from some events (classic SSDT?) because of this, but I wondered where else it might be excluded?? Thanks.

What size taper roller bearing do you guys use for villiers services yokes, they did not have any and meriden is out of stock as well?

I'm struggling to get hold of some alloy brake shoes for the Matchless (.. and AJS) WD hubs, has anyone ever tried to modify a set from another model to fit?

Hi all, sorry may have the wrong site but you may still be able to help me. I own a 1963 triumph tiger cub SH . I am having trouble with the timing on my bike. Having gone through all relevant stuff I'm now looking at the advanced timing unit ATU. Having removed the unit I find that there is a slot in the unit that I presume locates on a peg, but looking down the shaft of the camshaft I cannot see a location peg. My question is should it have a location peg or has it broken off at some point? Any ideas anyone? Thanks anyway

does anyone know the difference between the teardrop tanks offered by armac, upb and terry weedy besides price?

Hi all, anyone know where I can get any magnesium engines case covers for a C15, I very seen a few on bikes and just wondered if I could get my hands on any? Thanks

So, a mixed day today, the two Tufnol spacers have worked a treat and very little heat is being transferred back to the carb, great, happy days. However, after around 8 sections I get that very painful metal on metal noise. Diagnosis between sections ranged from, big end, small end, tappets, push rods, etc etc. I rode the bike back to van really slowly and after say 5 mins the noise had totally gone. I spoke to someone and tried to make the noise happen again, and after letting the engine run for a while and a few Andy Roberton type laps round the field the noise came back. Does anyone have any thoughts, it must be to do with the heat of the engine or the amount of tim…

Can anyone give me some pointers on a new B40 Project. I've been riding a pretty standard GB B40 frame forr a couple of years and would like to make the steering a bit tighter, anyone got any dimensions or offer any help? Mine has always been a bit of a sod when its hot. Anyone using an alloy barrel, if so where from.. thanks.

Hi all, I was looking at the pictures of the swan neck cub frames fitted with strengthening top tubes that double up as the oil tank. Can the same ones be fitted to a b40/c15 ? If so where can i get one and what is the best way of fitting them or guess who fits them ? Also if you can fit a cub sub-frame to a BSA frame can you also fit an ARMAC one and maybe the swinging arm ?? Cheers Steve.

Support your local charity shops. Last week I came across a copy of Don Morleys Classic British 4 stroke trial bikes in a local charity shop. It was in as new condition, and they wanted the pricely sum of

As an ongoing trials project I have been riding and working on a and '54 G3LS. I've recently converted to an all alloy engine, and as the next step I'm looking to make a few changes to the road based frame. As I am sure you will understand, I'm looking to steepen the angle of the steering head, and to swap the standard heavyweight swinging arm for the later lightweight version. I believe there used to be instructions for the swinging arm confersion posted on the AMOC site , but havn't been able to find them. Can anyone provide details of the best way to swap the swinging arms? Is it a case of changing the pin in the swinging arm, or do I need to alter the wid…
