Just overhauling a 4 speed D10 and I have a few spare parts that I do not need. : 

Original BSA wiring harness in good but grimy, condition but over 50 years old. Good as a pattern for those who like DIY. Includes original Wipac Ducon switch ( needs a little TLC). 

Original Wipac AC/DC rectifier and I am assured that it was working when the bike went into storage 48 years ago. Obviously no guarantees offered or implied now but you never know.

Pair of rear engine mounting plates and bolts. A bit rusty and a bit worn but usable.

A lower chainguard plate - these are getting rare now. 

Ideally swap for a B44 primary chaincase gasket  or a B175 exhaust pipe......adjust £ or givaway to a club member for cost of Postage and Packing.

No abuse please ....

Hi, Would be interested in the lower chainguard plate...my B175 did not have one so would be nice to get one. Also the Ducon switch...mine just about works but maybe I could make a good one from two.

PM me with what you want for them inc P&P. No rush till the new year

All the best

Cheers

Alan

Obviously the lower chainguard plate and the Ducon switch are now gone but the wiring loom and the rectum-fryer are still here if anybody wants them ?  If no response in 7 days I will take this post down to save space on the server.

Hello Sponge,

 

May I have dibs on the rectum-fryer please? 

 

It will help me put my twin switch bike back to spec. 

Sincerely

Dean.

Hi Dean, please send your postal address by PM and I will slam it into the mail next time I pass the Post Office. As stated theres no guarantees with this unit...I have not got the gear to test it ( unless I run up a bike) at present but its a genuine WIPAC part. Strength and Honour ......Sponge

Just to give Dean a heads-up. Selenium rectifiers have a quite short life (even if unused) and if they fail in service emit clouds of very nasty stuff (hence the name). If you use it as a dummy it's fine, but best to hide a modern silicon one somewhere unobtrusive.

Hi Cocorico, how right you are about these original rectum-fryers.

I bought a brand new unit, still in its unopened WIPAC packaging, at the exorbitant sum of £4.25 in 1972 from Bottomleys in Salford and kept it as a spare until 2008 when I fitted it to my B175......guess what....It didn't work. Although all bright and sparkly it was useless. I sold it on flea-bay to a bloke from Denmark as a non-functioning item for roughly £20 so I made a small profit anyway. He said he was going to dismantle it and  install a diode bridge. ( being a Dane he might have said possibly a bio-fridge or a cryo-squidge !!! But I am sure he enjoyed the experience).

The original factory fitted recifier on my other B175 still works fine to this day. I ride with the lights on nowadays and I think this helps. In the past I remember these things getting very hot, perhaps due to running long rides without lights and a battery fully charged...the rectifier has to dump the excess amps somewhere and it gets hot. Thats my theory....better to run with some electrical load......

Thanks for the heads up guys. 

My Francis Barnett had one, it came in a box of bits as the previous owner had fitted a solid state unit prior to stripping the bike down and leaving it in a garage for years! I acquired the stripped bike and put it back together. The solid state until went pop so I fitted the original rectifier. It worked fine but I always have lights on so that may have helped. They certainly used some dodgy stuff back then, working on older aircraft for the day job is like a science lesson in deadly chemicals. Some frightening stuff.

Cheers,

Dean.
