Pre-65 Bikes

Great looking bike, the Bantam is the way to go right? http://www.ebay.co.uk/itm/BSA-Bantam-Trials-B175-4-Speed-Center-Plug-Head-Rex-Caunt-Electronic-Ignition/121531189691?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D28111%26meid%3Dbde93385ac1d4697a86e51fec6b4ebc6%26pid%3D100005%26prg%3D11472%26rk%3D2%26rkt%3D6%26sd%3D181627618768&rt=nc Would this be eligible for the Scottish Pre 65?

hello I have a triumph tiger cub and just wondering about upgrading my forks ! does any one have any ideas what will fit and take my front wheel with no much hassle ???

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 ?

Can anyone suggest a reason why it would be a bad idea to chop the down tube on a cub frame and replace with a thick sumpgaurd (as in how the upb and armac design frames are configured). Obviously id have to keep the frame straight while attempting this operation. I would hopefully have a 5mm pre formed alloy bash plate made and replace bottom of downtube with this,can anyone suggest any downfallls pitfalls to this operation.

I'm seeking opinion on the best options for a Matchless engine. Is there any benefit in using the older 350 bottom half of the engine? It is smaller, lighter, and the smaller flywheels may suit modern sections better. Has anyone tried this with the later shorter con rod, which should give better torque? Or is there a better option?

anybody know whos making james alloy tanks ?

What is the maximum engine capacity that can be achieved on a 200(late motor) Cub without increasing the stroke?Anyone have any comments on the no doubt numerous ways of doing it?Cheers,ALT.

Strange bike at 4:37 anyone know what this watercooled two cylinder two stroke is? Part 1 of 3

Any recommendations for the best soldering iron to make up cables? I've been struggling with a gas torch which is just simply to hot. Also any hints on the best solder to use?

Hey I'm building a c15/b40 trials bike and I've just picked up some mz forks 35mm however there is no bushes??? The stantion seem to wobble a bit in the seals just wondered if these forks were supposed to have bushes or if this is normal? Cheers luke

Could anyone tell me what thread the 8 mounting bolts are for the sprocket on a Bantam/Cub hub? They are 1/4 diameter but not sure if they are BSF or cycle thread - or whether there is any difference! Thanks

I’ve just acquired a bantam D7 bottom end (everything accept a barrel piston & head) I would like to fit a D14 top end, I presume it’s a straight fit. But did the D14 have any difference to the crankshaft, crankcase volume or transfer port alignment? Basically what I want to know is, will I get the same power output as a D14?

So, in an attempt to make sure I've got the correct mixture I keep on checking the plug and after a few changes this is what it looks like I think it's looking pretty good, thoughts please?

I have an Ariel that since the engine was rebuilt many moons ago run on castrol R. It has to come out for a last minute trial on Sunday and I have no Castrol, will it harm it to just mix whats left in the oil tank with a normal 10/40, or do I need to drain it all out, or does it need to flushed / cleaned throughout before I add another type of OIL. I am sure I read somewhere that it could damage the engine if care wasn t taken when changing from Castrol R. Thanks.

does anybody know who supplies magicals fork springs now please.

How's this for a great looking Triumph?

.... bring on the Guy Fawkes trial. Might even try to get it painted before Sunday, am thinking black, with Silver coach lines and the obligatory flying 'M'.

So, still got the metal on metal noise after the bike has run for around 10 minutes. I sat looking at the engine tonight waiting for a eureka moment and maybe I had one. Have a look at the picture, could it be that as the oil heats up it just flows downhill to the inlet rocker and doesn't bother to flow uphill to the exhaust rocker? The oil starvation from the exhaust rocker then creates the noise.

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

Does anyone know if Norton Villiers are still going, I’ve sent a couple of emails with no reply? I keep meaning to ring but its not always easy when I’m working!
