Pre War / Re: Identify model please
« on: 23 August, 2017, 09:56:37 »
Hi Julian,
Just curious - what do you think about the mudguard shape in Emilios photo ? I've seen, "in the flesh" one 1929 500 cc twin port OHV with that wide mudguard with the forks penetrating the guard, but all others I've seen (including mine) have the narrow, valanced front guard.
Can't tell from the 1929 parts book if a mudguard option was that wide one or not.
Any ideas ?
Cheers,
Bevan

Hi Emilios,
I am no expert, but it looks your bike is a side valve and the fitting you asked about is a compression tap like part number 15-94 and EA 110 shown in the attached extract from a 1929 parts book.  A photo of the other side of the bike would be useful.
Cheers,
Bevan

The website "British Only Austria" has stands for sale, and "Cornucopia" have rear number plates and also springs for the stand.  The parts on both sites are expensive.

Hi Mike,
I have a photocopy of some data that I believe came from VCC records, showing 1931 and 1932 models as all starting with "Y7".  The last one on the page is 1932 Y7 5033, so presumably your one is 1933 or 1934, depending on how many they actually produced in those years ? Shame I haven't got the next page from their records - probably has numbers listed close to what you have.

For info, it also shows the 1931 & 1932 engine numbers with "Y10" prefix and numbers ranging from 570 up to 2535.

Cheers,
Bevan

Hi Ray,
I have forwarded an email reply I got from David, he included a couple of photos that I'll put into the Google drive folder you have access to, but since you've got your engine apart, you'll have seen it anyway.
Cheers,

The Star and Garter / Re: Sloper value
« on: 28 July, 2017, 10:22:43 »
Mike,
I bought an S29 500 ohv last year privately from a Norfolk seller for just over GBP 8000. No idea if this was good value, but it is a beautifully restored bike and I love it. It had all necessary paperwork and is fully road legal here in N Z.
Cheers

Pre War / Re: magdyno pickup
« on: 20 July, 2017, 06:49:51 »
Just a suggestion - I had a worn brush on the MO1L magdyno fitted to my Panther.  I bought a cheapish replacement which turned out to be useless - could only get the bike to fire up when I put the original one back in.  Some are too hard and others too soft I gather. Don't go the cheap route if you need a replacement; that would be my advice !
Cheers,

Pre War / 1929 Sloper crankcase breather
« on: 16 July, 2017, 22:15:55 »
Hi folks,
I suspect that my crankcase breather may be blocked.  If I remove the primary side oiler (which I gather acts as the breather (yes/no ?), should I be able to feel some air pressure if I put my finger over the breather hole when I kick the engine over slowly ?

I've attached (I hope) a couple of images of the oiler\breather .

Turning it over:

Hi Swoopster,
Best of luck with the repair.
I have an identical bike that I will need to strip down later this year, once other projects are out of the way.  I have quite a bit of information on these engines I could share with you - send me a PM if you are interested.

I'd be keen to see any photos of the progress of dismantling if you have the chance to take some - always good to know in advance what you are supposed to be seeing when you open things up.

Cheers,
Bevan

Pre War / Re: OHV Sloper Gearing
« on: 21 April, 2017, 20:45:23 »
Thanks for the prompt replies Julian and Dean.

Changing both sprockets should make a hell of a difference.  I wonder what on earth the bike had been used for in a past life to have such low gearing - maybe something like what was being done to the poor Panther in this picture.

Cheers,

Pre War / OHV Sloper Gearing
« on: 21 April, 2017, 04:29:48 »
Hi folks,
Since recently purchasing an S29 3 speed 500 cc ohv Sloper, I have felt that it was working pretty hard at speed. 

The 1930 BSA Instruction book quotes the following gearing for a 4.93 H.P. model: engine shaft 19 tooth; clutch chainwheel 48 tooth; gearbox driving sprocket 19 tooth; rear wheel 42 tooth.

Mine are as specified except that the rear is 46 tooth, so that suggests an obvious way to drop the revs I guess.

I would be interested to know what gearing owners of similar bikes have.

Cheers,
Bevan

Pre War / Re: Replacing Sloper fork spring
« on: 21 February, 2017, 18:14:01 »
Hi Dean,

I have a parts list, a 1930 "Book of the BSA", several useful Sloper articles by Bernal Osborne from old motorcycle magazines; also bought the complete set of the 1930 series "Motorcycle Repair" and Upkeep, which has a section on vintage BSA engines.  So I have quite a lot of engine and clutch info but not much about the frame, magneto, cycle parts etc.

I will look to purchase an owners handbook, but in the short term, a copy of the fork spring bit would be really useful.  My email is bevanc@actrix.co.nz if you are able to send it, that would be much appreciated.

Many thanks,
Bevan

Pre War / Re: Bsa magneto repair
« on: 21 February, 2017, 17:58:42 »
Thanks for that - I will definitely have to find/make up something suitable.  I've attached a photo of the points on my 1929 Sloper - no idea if they as per original design.
Cheers,

Good to know an Easycap will fit; I'll take closer look at mine. 

Out of curiosity, what do you use to tighten the nuts on the points ?  I had no spanner anywhere near slim enough (not even a set of points spanners I use on my Enfield) and ended up using fine nose pliers, which isn't ideal.  Was there originally some special tool ?
Cheers,

"I would suggest getting a Brightsparks condenser fitted while you are at it."

I'd second that, provided it fits, they are excellent. 

On my Panther magneto it fits inside the points housing, meaning that if it fails, you don't have to take the magneto apart, or even off to replace it.  I can't see how one would fit inside my BSA Sloper magneto points, there is scarcely enough room for the points mechanism.

Cheers,
Bevan
