Pre-65 Bikes

Hi all doing a bantam engine and I cant remember what gears I swop from mainshaft to lay shaft I think its main shaft 3rd with lay shaft 2nd the ones fixed with the circlip not the sliding gears . I wrote down the number of teeth 26 to22 and 25 to 21 but cant remember if its the fixed or sliding gears . Many thanks Martin

Hi all Anybody know a good starting point with jetting on a Mk 1 Amal carb , its to fit a Villiers 250cc 32A motor Cheers

Hi guys, I was helping my dad clear out one of his garages and in the corner lurking behind an enfield was a old BSA bantam rolling chasis, under a cloth there was an engine and other odds and sods looks like maybe 90% of the bike present. It is obviously a road bike and it is of the twinshock era rather then ridgid. My question is what work and cost would it take to make this basket case into a decent trials machine? Is it even worth the effort of should i do it back up into a road bike and flog it? If i could.convert it i would keep it but i dont have a road license.

Front wheel chrome is rough on my C15 trials and I have been looking for alternatives, forks are B44 clamp type at bottom of fork leg did any japanese/ european manufacturers ever use a 40 spoke alloy rim in 21" that I could change to I can find a lot of alternatives in 36 hole, and have toyed with the idea of lacing the 40 hole drum to a 36 hole rim, but sourcing the odd length spokes may be a problem any pointers appreciated

Hi guys, I have noticed that more and more twinshock and pre 65 bikes now have hollow ali spindles. where would you find theese or are they home made? Cheers

Hi Guys I am new to this forum i have a cub frame and modified subframe i am basically building a cub rolling chassis with all cub parts then putting a bantam engine in as that is all i have spare any bantam engine modifications or tiger cub parts that i should buy though they will have to be cheap as i am only 15 Cheers Sam Photos so far

Planning to rebuild a C15 to trials spec. Is there any value in pushing the engine out over 250cc which I believe you can do with a Triumph piston or is it best to use normal oversize.

Does anyone know the do's and don'ts re 35 mm yokes for use in the Scottish pre 65 trial. Trying to get my Bantam eligible, not too sure about the yokes. Whether I ride the trial remains to be seen but at least if the bike is eligible it's easier to sell if the time comes, But I will try to enter in the mean time when it's right.....

Sadly as yet no news is bad news and no sign of either the stolen van or the pre 65 parts that were inside has been recieved so not looking good and sadly it is beginning to look as if these were possibly stolen to order which is an option that not only saddens me but deeply worries me as Classic and pre 65 Trials riders i have always thought were a good bunch. In a previous post i informed as many as i could about Alan Whitton having his van stolen and that inside the van was the Bantam rolling chassis he had on show at Telford as a showcase for the parts he sells. Alan didnt have any photos at the time of this but someone has kindly responded to our request for a piccy…

Sorry to post this in this forum but i've just had a call from a distraught Alan Whitton who this morning has had his van stolen a white Transit connect LWB reg NC 56 KKN now Alan is less bothered about his van because insurance will sort that out but inside was his Bantam rolling chassis that he had on his stand at Telford show along with some Triumph Tiger Cub heads and various parts. Alan doesent have any photos of the rolling chassis and needs some for the Police so if ANYBODY has any piccys at all of the Bantam frame from Telford show could they please either post them on here or let me have them and i will forward them to Alan. Obviously if you know of anybody off…

"I heard a rumour, it was just a rumour..." great song btw. Siouxsie & the Banshees... Sorry back to topic. Does anyone have any news regards tubed tyres, are they being phased out? I understand stocks of tubed IRC's are far and few between. Would be interested to understrand the options, tube in non-tube tyre, tubeless??

Has anyone made an electronic ignition for a starmaker/stormer engine? I know electrex world have but i dont like thier customer service. any others out there?

For anyone with a pre 60 registered or manufactured bike/vehicle. I tried to tax my AJS today and the computer said no - Mot not on record,it runs out on the 20th of Feb.(One side of the form says Mot required,the other side says from the 20th of Nov 2012 its not needed) The new tax disc is from the 1st of march.Tried local post office and online,the helpful lady gave me a number to call.Some time and many options later I got hold of the chap that actually knows - you need a form V112 available here; http://www.direct.gov.uk/prod_consum_dg/groups/dg_digitalassets/@dg/@en/@motor/documents/digitalasset/dg_065277.pdf This will allow the post office to let you get your free…

Does anyone know if a C15 engine will fit into a bantam frame? I’ve built a rolling chassis for my bantam, no engine but I do have 3/4 of a c15 engine!
