Not sure if its a problem or just coincidence. But I have seen at least 4 separate Carrillo B25 rods for sale second hand, that had all spun there shells and wrecked the crank pin. As I am thinking of buying one new is this a problem with the B25 rod? what shells do they use, original bsa or carrill...

vetterlatethanever

wow is that still going! I think it might have grown out of the bike meet that stated at the ferryman pub in bablock hythe.
but I might be wrong. there used to be so many good bike nights in and around Oxford.

vetterlatethanever

There are some on Ebay right now both types i think.

vetterlatethanever

Wanted a late model B25 engine 71 or latter.
Or earlier one that has beeen uprated with a stronger rod.

A one gallon mx tank or a cheney tank.
Any starmaker bits you have littering your shed.

Hello b50 ers
Any if you going to the stafford show this weekend.
Ive been off the bike scean for a year or so due to personal injury and a move to cold wet north wales.
Be nice to see any if you there,
Cheers mark :)

You will have to cut the barrel less if you bore the B44 barrel to take a B50 piston as the gudgeon pin hight different works in you favour.

I am proberbly talking rubbish, But did I see stan say he recommends 65% on his high reving 250,s

vetterlatethanever

I am suprised you haven't modified a latter Japanese knee to your requirements. Ive got a 2014 modle on my right, And i must say its fantastic i can run around and play football again. No not us football the real kind. I can even kneel down and screed floors again, which got me into needing a new on...

Managed to blag a try of this Tank while i was at Howard's. It looks fantastic and weighed nothing. so if anyone has a tank that would suit the project get in touch please. I have now got another swinging arm an original Cheney one, It is dimensionally identical to the one i have in the frame except...

vetterlatethanever

Thanks for that Beat :) the project is coming together slowly. I just need the proper tank for it now and all the big bits will be there. i am considering getting a BSA bantam tank as to my eyes they look identical apart from the holes in the side to attach them. lol ;)

Hi ampshire, ive just had a look in my box of bits, The GP cam looks like an mx cam and the E marked cam looks just like a standard B25 cam, apart from the journal sizes as far as I can tell by the naked eye. Sorry i dont have an O cam to compare, my standard b25 isnt marked at all. but from memory ...

vetterlatethanever

I resisted saying that so much Chris, lol

vetterlatethanever

I am no expert but I took it I was a frame made for Jimmy Aird CCM rider?

vetterlatethanever

Hi longstroke I would have gone down the aberg route, but finding a swinging arm has been impossible. and I like the look of the older bikes a bit more. Fortunately the inside of the frame is like new probably because the oil filler hasn't been cut out yet and it must have had a protective oil coati...

vetterlatethanever

Thanks beat I will enjoy building it thats for sure. going to send it away again first though, The frame could do with being phosphated before powder coating. do you now what the frame oil filter and conecter is off ? and the steering stop rubbers are they the same as the oil in frame twins and t140...

well it looks like the old bugger is going to live! took it along to Howard of faber and here it is. hope you dont mind beat i gave him a pic of your frame and said "make it like that"

vetterlatethanever

No fastharry I haven't. I did try some of the more well known crank makers and engineering places.
I will give them a try many thanks

vetterlatethanever

Not really being picky mark as the B44GP was hard chromed, and if thats what hwan has on his barrel then thats what i want on mine lol.
The low wear rate he has is excellent.

vetterlatethanever

Andy can you confirm you are running a chrome bore and not a nicasil one?

vetterlatethanever

Frame looks good in gold. did you use Reddich powder coat, I am guessing there close to you.
I have heard good things about them and am just about to dispatch my frame to them.
if you did use them can you recommend them?
cheers mark

vetterlatethanever

My grandfather once came across an Italian tank like that minty do you think they are the same maker?

vetterlatethanever

I will would love to have gone to a welded and offset ground crank like you have Tom, But I have had no luck getting any place to take on the work. most didnt even reply to my emails or ring back after a phone call. one place said maybe but were talking telephone numbers. so standard 70mm stroke it ...

vetterlatethanever

I given myself a 10% pay cut this year mark so does that mean I can get 20% off now?

vetterlatethanever

Well the idea is to fit a B50 cylinder and head to an other wise stock late B25 bottom end.(apart from the rod cam and main bearings) With a 89mm bore and the sifton cam I got from the usa thats meant for flat track racing the B25 motor. I have had the cases welded and retapped and opened up to take...

vetterlatethanever

Your a genius minty. and it wont be seen behind the lower fairing in anycase

vetterlatethanever

The must get countdown minty look at all the other crap we have flogged em over the years.

Off the tops going to be the easiest but the head might look a little odd hanging over the sides

vetterlatethanever

ok so a bit of sage advice wanted. I have a B50 barrel on the bench that needs a new liner its cracked. so while its out I also need to shorten it to suit a stroke of 70mm. If you were going to take 20mm off a b50 barrel would you chop it all off the bottom, all off the top, or take ten from the top...

vetterlatethanever

The build is looking great! can i just stick my 2 pennath in and say dont use felt on the roof of any kind, Fibreglass it, (have a look on you tube if you need to its very easy to do though) as a builder of almost 40 years i have made more money out of felt roof leaks than most other roof repairs an...

vetterlatethanever

Thanks I think I will, didnt look right to me. what do most people find is a good cam with a bigbore B50 and a 3 speed box for mx work?

vetterlatethanever

http://www.ebay.co.uk/itm/172135893102? ... EBIDX%3AIT

Can anyone confirm this is a CCM cam profile? it looks like the exhaust lobe is pretty wild.
would profile suit a 550 with a 3 speed gearbox.

thanks lads :)

vetterlatethanever

Doesn't seam to be a head with it just a rocker cover and a load of other bits.

vetterlatethanever

Thanks lads thats more or less what i knew you would say. But wantet to hear it for myself before ordering 3 carillo rods
So whos doing them at the best price at the moment.?

vetterlatethanever

I was just wondering has anyone had the rod trouble so prevalent on the B50 with there B44's
I am especially keen to here form anyone using an over bored B44 to 500cc or has race tuned there B44, who has used it trouble free with the original BSA rod.

vetterlatethanever

Thanks Trevor and Bill, you both made valid points i never thought about. I will just file that idea away with my carbon fiber pushrod experiment. That didnt work to well either lol.

vetterlatethanever

I have been wondering about casting my own in-situ, There are lots of different Polyurethane Rubbers compounds available for home casting. so you could tailor them to suit your application precisely.
