the one I know of is near Chesterfield. If you are seriously interested I'll try and get details and PM you.

The club has a reasonable selection of used spares and has had quite a few parts re-made

They tend to be pretty resilient, as do their owners, judging by this story...

The BSA Front Wheel Drive Club has info on BSA cars including trikes.
Complete Trikes are fetching a lot of money these days but of you fabcy a serious project I know of a dismantled one that is pretty much complete. It is a four cylinder engine model though.

TTJohn. thanks for your informative and reassuring reply. Off tomorrow to get the barrel bored to fit the STD piston!

Mike. I have seen the pistons you describe, with a ring towards the bottom of the piston, on the original epuip BSA V-twin trike (but I'm running on B33 pistons as they are a damned sight lighter!). So perhaps its a prewar thing.

I've got a piston but needed rings. I can only find the usual three ring sets yet the piston I have has 4 ring grooves. The top (extra) one is thinner than the other, non oil ring. Having just got a NOS BSA replacement piston this also has 4 grooves but came with rings fiited, but only three. the top groove has no ring. Perhaps the top groove is not a ring groove but serves some other purpose. I've not come across this before so can anybody explain what's going on?

Pre War / Re: OHV Sloper Gearing

for solo work you want
Engine 21
Gearbox 19
Rear wheel 42

Changing the engine sprocket may be the eaiest/cheapest option. M20 and A10 4 lobe engine sprockets fit the Sloper and are easily available.

Its ironioc that you need to gear up just as I am trying to gear down!

Singles / Re: B25 Kickstart Problems
« on: 16 April, 2017, 20:55:50 »
There were similaer problems with some pattern A10 kickstarts. I seem to recall the cotter pin holes were not to original spec. My solution was to buy another one from a different supplier. This fitted nice and securely to the kickstart shaft but hit the silencer >:(
Next time I'll go for a tatty OE one and fork out for refurbing.

Let us know which shows you decide to show it at.

Originality is good but have you ever considered improving it. I notice for example they had not finished the job and left the tyres unsectioned.

Sidecars / A bit in the side
« on: 13 April, 2017, 19:48:34 »
I can't recall why but some time ago I decided I would fit a sidecar to the Sloper. So I found a period chassis and braked wheel locally and sorted out the fittings. Boxing day 2015 I got bored so started building a body. I had alreday decided on a replica BSA Model 7 as I only needed a single seater.

Only then did I think about gearing down the engine to cope with the extra load. I was a bit of a twit really not to make sure I could sort this before all the effort to on the chair. The Sloper owners' handbook is very helpful in explaning how to set up a sidecar and the engine gearing options. But could I find an engine sprocket for a 29 Sloper...not  a chance. I even visited a local gear manufacturer who offered to have a go at making one. 150 if it worked, no charge of it didn't, whcih is decent of him but an expensive way of getting a sprocket especially as I would be guessing at the size to go for.

Then as it happens I obtained an M20 engine sprocket this week (it came with the bits of an almost entire bike) so I thought I'd might as well try my luck and see how close a fit is was on the Sloper. Its fits!!!!! So, I have an 18 tooth sprocket on order as I type (19 plus postage). Oh happy man ;D

Only trouble is that when I fit the sidecar I have no space left to store it, which is probaly why its taken me nearly three years to get the job done >:(
Another begging letter in the local newsletter asking for storage space will be appearing soon.
