Pre-65 Bikes

Just wondering how many people stick to Bantam forks when doing a Pre 65 Bantam trials build, are they usable? what mods if any? or is the C15 fork conversion a better bet? I've already got some Bantam forks (D7) so would like to use them if they're suitable, but if not I'll look for others, any recomendations? Thanks.

Hello everyone, right then, a pre65 James with a villiers 8e in, now I want to stay within the spirit of pre65 so, can anyone advise on the best engine eg stick with what I have or go for a 32a? Also what sort of mods can be done for better performance to either of these engines? Any advice greatly received just don't start on "the spirit" issue - each to his/her own,

Can anyone help me? I need a new trials frame for my B40. Looking at a Faber Mk3 but am being put off by reports that Faber can be difficult to deal with. I'm near to Preston, Lancashire. I believe there is a frame make by the name of Roger Heap. Has anyone got his details? Jeff

Hi Guys, Does anybody know any information on the following machine. BSA 441cc Victor ISDT machine. Registered No HOE 14D. I rode this factory machine in the 1966 ISDT in Sweeden. I would love to know of it's whereabouts, and what it is doing now. I have enquired of the DVLA but they inform me that as was not the registered owner of the machine BSA were, they can not tell me where the machine is now or who the registered owner is. Basicaly the machine was a 441 cc Victor scrambler. It was modified for the ISDT, one of the striking features was a large alloy fuel tank basicaly the same shape as the standard Victor one. I do have a photo of the machine but for some reason …

i have a greeves scottish does anyone know if you can buy a bash plate for them or just make them yourself ?

Some help please guy's. I have just had a British hub co hub c/w with cushdrive assembly restrung with stainless spokes and a new Morad 2.15 alloy rim. All looks lovely with new sprocket and hub powder coated etc etc. However when offered into the James Captain K7 frame and swingarm with the rear drive sprocket aligned to the engine sprocket, the centre of the tyre is about 1" offset to the right of the frame, making the wheel offset to the centre line of the frame. There is an element of adjustment that I have made with spacers etc, but to get the wheel centralised to the centre line of the frame means that the chain is misaligned to the engine drive sprocket. I was …

Could someone help with an answer to my silly question?. I have just purchased a set of the new type of tube gaskets, the set comes with a large black rubber seal which I assume goes in the bottom and two composite type gaskets of different thicknesses . The black one was a right pain to get in as it seemed too thick but I eventually got it in with the aid of some silicon lube, Now for the silly question; what do you do with the TWO composite gaskets?? I would rather ask the question and get advice before putting it together and it leaking. (My cub has a square barrel and head) any advice gladly received

Can anyone recomend which tyres works well on Pre 65 and should they be used with a tube or tubless

Hi all, Having managed to oil up NGK B6HS at a rate of roughly 1 per trial, would it do any harm trying a slightly hotter NGK B5HS? I won't be riding the bike on the road! Does anyone else use these in their Cub? Bruce.

I need to identify this rear hub and sprocket from my new project. It looks a Triumph to me but not sure, actually it´s in a old James, a quite original bike. Any idea? Thanks for the help.

Hi there As the question says ! I've got a sprite with 37a engine and my son has a James with 8e engine Is modern 2 stroke ok ? If so what ratio Cheers John

Hi: I own this Greeves bike, but the sprockets obviously are not correct as the bike is too fast in 1st gear. Somebody knows the correct sprockets? and maybe where to find them in the internet? It is really a pre-65 bike or not??????? Thank you

Ok so i am in the midst of my greeves/honda project. Taking a honda tl125 engine and transplanting it into a greeves (what i think is a pathfinder) chassis. I call it Gronda.... I have heard of Hondeeves projects but i wanted to be different. So while it was down to bare chassis I decided that this thing needs a proper skid plate. My dad has another path finder and two other Anglians and his designs were not to my liking. This frame was my christmas present from him. I cant start to tell you how excited i was... <<<i am such a trials nerd! So here is what I did. I acutally did this earlier this winter but just getting around to posting it. I did this with st…

Hi I am new to the site & to trials too, though have built from scratch many British Frame based specials over the years. I have a couple of old Bantams, one based on a 69/70 B175 Bushman,which has been Trialled for 2 or 3 years, t'other is a D10 engined D7 & its gonna be a Trials style road runabout! I have a friend who is going to rebuild the Wheels for me shortly, & for the rear I wondered if anyone could advise what offset from central to have the rear wheels laced. I have 4.00 x 18" rear Trials Tyres, & was intending to use WM3 Rims, though it has been said that WM2 Rims should be used? I have some thicker rear engine plates from Rex Caunt Racing,…

I am going to need a new rear sprocket for my Pre-65 Trials bike soon. It's a BSA B40 with Triumph Cub wheels, using 428 chain. I am currently running a 76 tooth sprocket, and had once purchased a replacement rear from PMP sprockets in Wylie TX. I was very pleased with. Sadly, they are no longer in business, and from all I can tell, the business was bought & operated under Superior Sprockets name. When I follow down that rabbit hole, their website is "Temporarily Closed". Does anyone have any experienc with other custom sprocket makers who might still be in business? I'm going to be in need very soon! Thanks

Assuming there is an alignment of the planets sometime in the near future and my new James frame materializes then i will need to get some wheels built so i'm gathering bits as i go along ready for if it arrives. So guys i've been offered alloy rims in both WM2 and WM3 but i dont know which to choose In the past i've never given it a thought and just used what was fitted, mostly WM2 i think, as std. I assume that WM2 being slightly narrower would give a rounder tread profile to the tyre and WM3 being slightly wider would give a more square or flatter tread profile. Would the WM3 however close the treads up and the WM2 open them slightly ? Which would give better gr…

BP4ES plugs are hard to come by (unless you know differently)so I was using a Champion N16Y which is the equivalent. Now they seem to be in short supply but I can get N16YC. The question is, although I know the C stands for copper, does it make any difference ? Thanks Ross

Hi guys, I want to try and repair a small crack in the bottom skirt of a Tiger Cub cylinder. The bike will not be used on too much of a regular basis, so I hope that this repair can be successful. I am in two minds though as to how approach this repair. Do I braze it, Oxy/acetylene weld, CO2 or similar inert gas weld. Has anyone tried this? My head tells me to braze it from a joint aspect because it is flexible, but from a welding heat aspect, a quicker CO2 weld seems to be the way to go. Obvioualy the crack will be prepared accordingly prior to repair. Bruce
