Pre-65 Bikes

Hi all, does anyone know of any Mick Mills type frames out there for sale?

I'm now about to start building a shortstroke 500 Ariel.This afternoon I laid out all the bits I've got so far,so I can make a list of what I need.I then started looking at the 350 crank and rod I bought ages ago,it occurred to me how much of the flywheels is cut away compared to the crank in my AJS. I wonder if anyone has compared the weight of a complete shortstroke engine to the original long stroke ? Must be quite a bit lighter with an inch less of barrel aswell. Also wondering if people use the same carb with similar settings ?

Tight clutch plates I am trying to replace my clutch plates and after fitting, new clutch plates the clutch drags. The new clutch plates are very tight! do I need to file them down on the 3 corners ? of the sqaure lugs or just the sides. When I fitted them with the clutch hot they slid in OK. But when cold were tight. Will I damage the plates by filing them?. Are there any clutch advice sites anywere, have looked on Google no luck.

Anyone know if and where you can purchase longer than standard Stantions with springs ?

looking for Greeves Scottish hubs. will pay cash.

the tail pipe on my villers engined bike is so close to the tyre as it passes inside the frame that it is wearing through. My question is does the tail pipe at the exit of the silencer serve an purpose? does its length effect performance? clearly if i mod it to fit easily inside the frame i will reduce its volume which i believe will restrict performance would shortening it so that only an inch extends from the silencer have any affect on performance?

a simple question for a monday morning.. are the rear engine mountings on the villiers 9e/32a/37a gearbox all the same width?

Can anyone tell me the chain length I need for a bsa c15 with 13t engine sprocket and 62 rear wheel sprocket??? Longer would be better as I can chop it down cheers luke...

Could anybody please point me in the right direction regarding the above bike owned from new by my trialing uncle. He is looking to restore the bike to original condition could anybody please recommend a company or individual who is capable of carrying out the work. Would prefer East Anglia or South East. Many thanks

Hi, I am looking for 2 x C15 gears to put in my Distributer type engine. Well actually I would like a complete wide ratio box for the bike but hens teeth are easier (and cheaper) to find!! I am looking for a 20T part No 40-3101 & 30T Part No 40-3100 These were fitted as 2nd gear in the wide ratio box. I have tried all the shops who advertise in Classic bike and Old bike mart hoping to find some NOS but no luck. Can anyone help? stephen.bird1@ntlworld.com

About 2 or 3 weeks ago I saw an advert somewhere from someone selling B40/C15 trials gears for

I am thinking of having a go at pre 65 and am thinking along the lines of a bantam after reading and asking around the general consensus seems to be 175 with 4 speed box a D14/4 but will this be eligible as a pre 65 considering they were not in production untill 67 68 ? many thanks in advance

Long ago I think I read of a method to convert RE Crusader ignition to manual control, ie the old fashion advanced and retard lever set up. Anyone with a better memory that mine out there?

Hi there, I was wondering if anyone knows what length the forks should be from the top of the top yoke to the centre of the wheel spindle, on my dads Drayton bantam.

Hi, in a previous listing I saw reference to the difference offered with amal carbs of a 2 stroke and a 4 stroke needle. On tinkering today, dont know why as runs like a hamsters heart, albiet if hamsters suffer that vibration at low revs i dont think they could walk straight, i noticed that needle has 1 identifying groove above the clip setting grooves. In Rupert Ratios book this identifies it as a 2 stroke needle (4 stroke 2 identifying grooves). Someone mentioned that the 2 stroke needle is shorter, would this meam or explain C15 with 622-301 running rich not getting the metering of the longer needle at higher revs or am I looking at worn parts anyway. Only info I can …

hey after looking to bild an ariel i've changed my mind, it wil be a B40 what frame options are there? (prefer oil in frame) i would like to bild something like Martin Wilmore's bsa (not the super special one that looks like a sherco) advise on the engine is very welcome to i would like it to be powerful, smooth and high reving (like my sherco) and the clutch must be good does anyone have email adress of M. Wilmore? regards bob

Hi there Back again with more questions Got the chance of a bored out Cub barrel but don't know which piston to use? The Barrel is 68mm from 63mm & I would like to avoid any issues with a change of stroke. Is there a straight replacement at 68mm? Thank's Frank

Dad has said I can give this a try if I promise to not get it dirty or crash in a big heap. That was 4 years ago and I still can't make that promise. But he's gonna let me ride it anyway. Boxing Day trial perhaps. Just need the right venue. Midlands area

Many of you may already know this and if so apologies for stating the obvious. having recently purchased 2 Amal Mk1 carbs, the premier type, i was dismayed by the strength of the slide spring, I am no weakling but you needed two hands to open the the throttle, lso when it snapped back it sounded like the throttle stop screw was going to bust off. living quite close to the AMAL people in Salisbury, i dropped in to have a moan and ask if they had any suggestions. They were very helpful and merely said. oh yeah loads of people complain, you are not alone, we fit the throttle slide spring out of the carbs that go on the triples, alot of trials and motocross boys do it. …
