IVE JUST REBUILT A 1964 TIGER CUB AND ITS HAD THE ALTERATION TO THE FRAME WHERE A MILLER CYLINDRICAL OIL TANK IS FITTED. I KNOW THE TIGER IS A WET SUMP ENGINE BUT CAN ANYONE TELL ME HOW MUCH OIL GOES IN THE TANK. A SET AMOUNT OR FULL. THANKS

Good evening all. I'm going to change the engine oil on my otter framed B40. Could anyone please give me some advice? Where is the drain plug and how do you get the right oil level ect? Many thank

Hi, I am just finishing a Tiger cub trials project and would appreciate any advice on the rear sprocket. The current chain is a 520 and I see from the manuals and most postings that a 420 is the standard size. The 520 clears everything and I would like to stay with this if possible as it will be stronger and will cope with the awesome power of the 275cc upgrade on it...... Joking, the power is still not arm-wrenching but it does sound excellent! ;o) All the sprockets I can find on the interweb are 420, can anyone advise on where to go for a 520? Best Regards

Hello all I'm after some advice please. I have a bsa b40 with a wd engine. She's been sitting for a while and the carb has all disintegrated. Could anyone tell me what AMAL carb it has fitted please so I can try and source another. From what I can see it's a 626 L but all the one's on the net seem to be L and three numbers. Many thanks

Hi all, looking to build up a B40 and need some new hubs. Quite like the look of the billet hubs, where is the best place to get them? I’ve heard they can differ depending where they come from.

Hello All, long time reader first time poster 😀 I own a pre65 Triumph cub with an original swing arm. I am wanting to run a modern trials tyre however things are tight down there 🤣 I understand that Feked do a trials swing arm to give more clearance however i was wanting to hear from those that have modified the original swing arm quite sucessfully without going down the feked path. Many thanks

Just bought a Trifield rolling chassis , has short road shocks fitted... Anyone here know the ideal shock length eye to eye ? Thanks

Hi, how much tarmac road work is there on the Arbuthnot trial please ?

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

Am needing some help/advice. Have bought a 1961 T20 and recently topped up the primary chain case with oil, on the next run found it had leaked out onto the drive sprocket. I'd put in red ATF, so the leak was definitely from the primary chain case. I've not had a T20 engine apart, but I know that on the Triumph 500 and 650's there is an oil seal set into the back plate behind the clutch assembly. I can see that this engine doesn't have a removeable back plate, can someone point me in the right direction, is there an oil seal on the inboard side of the primary chain case and is it accessible once the clutch has been removed, the Haynes manual is pretty vague. Thanks.

I first saw a 350 CCM in action when Dave Thorpe struggled round the Scottish way back in... whenever it was. Saw one for sale a bit later and took the plunge. Did a few SE Centre trials on it, got the four stroke bug and swapped it for... can't remember, possibly a 350 Ajay (no, it was a 250 Honda Pinkie from Gordon Farley's Ash shop). The buyer bought it on behalf of an American enthusiast who was intending to rebuild 'as new', so it went off to the USA where I presume it still resides, possibly in a millionaire's collection, or museum. Must be worth quite a few bob now I suppose. Out of curiosity, I revisited my bike blog to check out the 350CCM posting where I listed …

Hi. I’m embarking in my first Villiers project. This is a Francis Barnett with an 8E engine and 4 speed box. I’m after some advice on gearing and primary ratios, so here goes - To begin with I’ll be using the standard clutch. I have though about lowering the primary ratio but figure that may introduce some clutch slip. Currently the ‘box of bits’ includes a clutch with 38t and a primary sprocket of 19t. Should I go lower than the 19t? - Final drive I can go 13t/50t by looking at the Villiers Services shop. Do anyone have problems with chain issues using a 13t? - Final one, given the answers above is there any benefit in going low 2nd? Is there some…

Can anyone help????? I purchased a cub frame which was supposedly fitted with a wide swinging arm..... However I'm begining to wonder if it is.... Does anyone know the actual width of a standard cub S/A or a standard cub wide S/A so I can check which I have.... I dont want to modify it if it is a wide one as I'm building a stock looking trial's cub with correct steel tank's fork's etc rather than a trick one...... Pete

I've been searching the internet for over two weeks and I can't find a lower crankrod pin, bushing or roller (bearing) for a E3342 rod (what the little Terrior used). I've found the larger crank pin, bush and roller, but not the small. I've contacted Greystone and looked on Feked, but they do not show these parts as being available. Any help would be greatly appreciated... I've got mine all torn apart and want to get it back together with new parts. Thank you.

Mine´s on a ROA Super Foxter 200 (1960) that’s not run for about 40 years. Its a Spanish bike fitted with a Villers 197 7E. As far as I know, there´s nothing wrong with the box, apart from 28,000 Km of wear and tear and 40 years of rusting in a barn…Unfortunately, when it comes to the gearbox, I´ve fallen at the first hurdle. From what I´ve read in Motor Cycle & Cycle Trader´s Servicing Data Sheet No. 4 and referring to the exploded diagram (Parts System | EXG074 (villiers.info) the “Bush operating shaft outer” (9) should just slide off the operator shaft (20). But its stuck solid. No amount of pulling, heating or WD-40 has shifted it a mm. Any suggestions on whe…

Hi folks, just a question for future sprocket alternatives. I have a motor which is B40 cases, with B44 crank and top end, 23 eng sprocket and 52 clutch....gearbox is 11 teeth with 55 on rear. I'm guessing standard side point motor gear box ratio's, but no clue realy. So bike handles sections in first gear reasonably well if not realy tight, and second good for hill climbs, so quite usable. Was just wondering if I went to a 18 tooth engine sprocket....I may be able to go up a tooth or two on the gear box and less teeth on the rear and shorter chain, and still lower the overall gearing slightly. Sounds feasable to me, but any input welcome. My biggest wor…
