Jesser BSA - this is pretty special
« on: 31.07. 2015 06:22 »
Not mine, but the owner has given me permission to share this period machine which I had the pleasure to see today  *respect*.
There is some neat detail that I'm going to leave it to you all to notice   *shh*

Its in need of a rebuild but is a methanol short rod motor. I've offered the owner support for the rebuild. Bwah hah hah  *work*
It is clearly in a high state of tune and yes that's a crack in the cases

Enjoy. and yes it has one wheel too many  *conf2*

Very trick machine by the looks of it.

RR do you know where the "Jesser" name comes into it ? I used to know a Dean Jesser in Adelaide but he was mostly known for tuning Triumphs, do you know if there is any connection. He had a motorcycle engineering business called L&K Enterprises.

The owner knows all the history, sadly my memory is rubbish when it comes to recalling names but yes this is a historic south australian machine.
Its always been A10 powered and won its fair share of competition back in the day

Different looking crank end feed conversion. The left carb would be hard to tune, it's a right hand. Later 6 spring clutch so must have a s/a mainshaft.
Cheers

If this was built by the people I think it was they were Les and Dean Jesser from Adelaide.

I never knew they ever built a BSA based motor, usually they built Triumphs  and had some very noteable bikes ridden by "famous" riders including Kenny Blake.

I never met Les but had quite a few conversations with Dean. They had a motorcycle engineering business in Adelaide and I used to get my rebores, crankgrinds etc done by them. Whenever I went there Dean would always have something interesting to show me and no doubt many others who showed an interest.

As always I wish I had taken more notice of what I was told and what I saw.

Its not a sidecar  *fight*   Definitely cheating having 4 wheels when 3 is the optimum number for entertainment  *grins*

I do like the bsa front wheels though!

 Yo, and all the above re; one wheel too many... *????*

 I take it this was a  road racer..?...slightly off, but;  Back when I had to keep my Road rocket alive, I had to source bits from all kinds of places, and frequently ended up harassing guys in the speedway field who ran units in the "TQ" class- seemed it was common to run long-stroketriumph pre-units with A10 cranks (upped the capacity )...which helped to deplete the supply of said cranks..???
