Hi Tidyrob69 and All
Any wear in the clevis pins and linkages will make the gear change sloppy and cause missed gears
I can see a gap between pin and clevis in the photo's
Sort those out and the gear change will be as good as possible

Hi Leon,
The ohv V twins are a thing of beauty,
I have never see one in the metal though, I met a Man from Austria who said there is one in a Museum over there
I seem to remember reading about some make of motorcycle using one for the TT in the mid 20's ???

I had saved a couple of pics of Blackburne ohv V twin (Tomtit) and 3 cyl radial (Thrush) engines intended for light aircraft. The engines intended for aero use have steel cylinders
There's some video on You tube of a Chater Lea  cycle car with a v twin Blackburne aero engine fitted

 Hi Leon,
It's a nicely-made thing, and the flywheel is almost unbelievably huge.

Yes, They sure knew how to make a flywheel  ::)
The one on my 350ohv is a fraction of the weight

Hi Leon,
Certainly a "Project"  ::)
Blackburne as far as I can figure out used the same head  on the front cylinder of the V twin on some of the singles, the singles need a curved inlet tube to match, The single and twin cylinders should be the same

A BSA long rod B33 piston is a good substitute, needing a little shortening on the skirt
I had to make a new split big end bush which was an interesting and time consuming exercise to fit the reground crank, bolted together with Austin 10 big end bolts  :o on the single engine pictured

Hi All,
The  Massey looks to be fitted with an engine almost identical to the 1920 version that I rebuilt a couple of years ago for a "Blackburne" motorcycle
I would need to go and read through the Blackburne parts books to see if they still used the same plain bearing
big end and mains  by 1927?
Or did Massey just buy old stock Blackburne engines?
I know of another Blackburne motorcycle where the owners Father took the bike as a trade in some time in the 20'swith a kaput engine!!,
The Father bought a complete new engine from Blackburne,
The lot sat and parts were lost over the years :(
A few years ago I helped the owner with some patterns and parts to get the bike together
Imagine the thrill of hearing a brand new 1920's engine fire up for the first time  ;D

Hi Neville,
Hmm??? Ok the front half is BSA but next question is what is the rear half?
The BSA rear frame did not extend along under the engine and gearbox
The joint where the front and rear halves of the BSA frame meet that also takes the centre stand pivot
is a high wear point and causes a "hinge in the middle"  >:(

Hi All
Just to throw  a further spanner in the works  ::)
I wonder if the frame number is Z C10 which would make that BSA as well
The front half of the frame has BSA features not to mind the forks fitting so nicely ???

Hi Stew,
It looks like he was on a works provided BSA Goldstar/Silverstar (not exactly sure what as it appears to be some sort of factory hybrid possibly)

The frame and engine numbers in the log book are both KM23 Silver Star
KM101 being the first production number for the 1939 model year
Its a fascinating story and I hope you find out more

Hi Cruise
Could you measure the radius of the dynamo cradle seating as some Miller dynamo's are/were a different diamater to Lucas,
It might be easier to find a Lucas E3HB than a Miller ?
Some while ago I fitted an Alton (Lucas size 3in.) to a Vincent that originally had a 3 1/2in Miller
Similar to your RE the cradle was part of the crankcase
A conversion sleeve is available for the Vincent's, eccentrically bored so you can adjust the sprocket mesh
It might provide a solution for your RE ????
Have you asked Modak about a dynamo? Lucas or Miller

Hi Helmut and All,
I thought OEC at first look, front lower of the frame and centre stand being similar
The the drive chain is not on the "correct" side for a British bike ??? they are almost always on the left side

Hi Jon,
Yes pretty much any condenser will work
There may be a value stamped on the old Hella one? but + or - 0.2microfarad will be ok

Hi mini-me
I had included that link in my earlier reply ???

Hi Cruise,
Some googling shows up a few pics of such a model
From one of them it looks like the base for the "mag or dynamo? is semicircular ?
This would tend to indicate that mini-me is on the right track
I cannot identify the unit fitted in the attached photo,
Another photo in google images shows a mag dynamo fitted to a 250 ???? (it says 1951)

Good luck with it

Hi All,
Besides the numbers the only difference between the round and wedge tank engines is the timing cover
The Round tank has a simple worm oil pump that delivers oil to the tank mounted adjuster and sight feed
the wedge tank has the adjuster and sight feed mounted on the timing case
This unit is made from zinc alloy and is often /easily damaged, replacement units are available though
Better deal to go to the maker, joseph60.7771 on eBay rather than

I have to recommend Joseph's BSA and Rudge parts they are absolutely first class  8) 8)
