Identify these bikes! / Re: What do you think this is?
« on: December 02, 2011, 09:25:44 PM »
I do have a photo which will make every vintage bike fan cringe, a Vincent engine for target practice.

Vincent enthusiasts won't cringe - the Picador engine program was the saving of Vincents, the money for the program funded a lot of engine research.  Whether they spent more than they got is another question....

And did anyone ever hit the target anyway ??

A famous story is that all the top brass were gathered to see the remote-controlled drone demonstrated. And someone not experienced operated the controls on a cloudy day - flying by sound effects was not the way to do it, and the drone "ended up in the drink" (ocean). Brass were not impressed.
BTW, the Australian Jindavik program about took over from where Vincents left off.
But jet powered.

Don't know what it is, but you could turn up at an airshow with that and they'd have to let you in the gate !!  Great pix...

P.S. Which wheel(s) drive it ?

The WW2 Royal Enfield WD/C has a front brake drum and hub very similar to that, if not identical. 350cc sidebanger, 1941 and 1942. Front speedo drive and all.  Is that a khaki green look to it. ?  Could have been on other small models of about then too, they made rather a lot of them, and they are not well known.

The rim lacing pattern looks rather odd though.
The original rim had an equally odd 3 spokes in a row on the rim and then one offset, so maybe its been relaced up with the wrong rim, and someone has adapted it ? !!

Actually, ES2's and Model 50s were sold in widelines for 1959 AND 1960.
But were not bolt-on rear subframes...

I'm sure we are all learning something for folks asking interesting and technical questions, keep asking away.

Suzuki TL1000 buckets are 28mm apparently.
And bigger than most modern stuff... ?

It may be possible to plate it or metalspray it with something if this is the only size available. Or sleeve the bore down.

When was this (year) ?

Interesting frame pic, Thanks. Clear from this view it is quite different, but based on a manx type frame.  Those wheel types still look very similar, and the hole for where the front brake cable point used to be is still visible, before the brake was changed around.

A note on the Ronald Peck Special notes that it was fitted into a manx style frame sometime after that pic above was taken, still with earles type  forks though. These engines still rather look alike - can we see a pic of the clutch side of the engine, that clutch housing is very distinctive.
Cheers.

I missed that frame pic somehow, yes it does look like its based on a featherbed but different in detail. Be interesting to see a side on shot though.

Does this look familiar at all ?
This is the Ronald Peck Special, with the man himself aboard.
Said to have been started in the early 1950s, and worked on for quite some years.
What caught my eye was the wheels and brakes, which seem quite similar in type, anyone identify them ? Perhaps this inspired some similar types ?

Someone like Cosworth could likely make those cam buckets, probably at vast expense. Finding someone to do them at home could be a little trickier.
Have asked some people if they can suggest anything similar.
Cheers.

Wow, to begin,  that is one fabulous piece of motorcycle racing history.

Firstly, the frame appears to be based on a wideline Norton - if its not actually a genuine Norton featherbed or even a genuine manx featherbed frame. If you can find any numbers on it anywhere may identify it. Look on the left side of the swingarm support. A view of the whole thing could assist with narrowing it down a bit.

Now, that engine. Without seeing it all asembled in the bike, that engine bears quite some resemblance to a 250/4 that was built and raced from the early 1950s. The name that springs to mind was the Ronald Peck Special. Any relation ?  Syd Mularney later reportedly had it, and it was then sold on.  If its not that bike, it is something closely related ?  Any history would be quite interesting.
At some point we are probably going to ask your fathers name....

Potentially, it could be quite valuable, is historically significant in the extreme, and well worth restoring to race-worthy condition.
We assume you are in the UK ?

Got a pic of the rusty bits requiring replacement - or a pic of some clean bits requiring duplicating ?. Potentially a lot of engineering fiirms could do this, but reasonable cost is going to be a factor ? Perhaps someone knows some  4 cylinder specialists for older machines . ?  Might see who is suggested before commenting.

Thanks for pics.
Cheers.

40 years ago, anything that revved to 14k rpm would have been a bit special !!
Fire away with the pics,

Some of the rockets these days have tachos redlined at 17k  (and you get a warranty), bits may be useable.  But understand that something homemade may be unlike anything available.     Cheers.

Given that it sounds like they have sold you parts for a modern carb, you'd have to think that whoever you spoke to didn't have a clue.

Assuming you are in the UK, the name Martyn Bratby is mentioned in connection with older carbs. Hopefully someone can advise how to contact him.
Getting someone to fully set up what was even then quite a sophisticated intrument can be well worth it in the long run.. HopethisHelps.

British Bikes / Re: Enfield cush-drive hub?
« on: November 12, 2011, 09:56:01 PM »
Definitely an Enfield design of hub - that cush drive is very distinctive.

Enfields themselves used this hub of course, and that hollow axle idea - prewar Enfields for some years had sprocket and brake drum on opposite sides.
And being a smaller size of drum, was for the smaller models of Enfields. I notice, for example, the Models B, C, L, LO and G for 1935 had a rear 6 &1/2" drum, among many such examples and years.
The larger models tended to use a bigger drum - which became detachable at some point.   HopethisHelps.

Not knowing these at all, they would have been metal-spun in a lathe. ?

While such folk are rare these days, they are not extinct ?
A search through your local phone book will probably produce someone.

Easy to test some of these.
Take off the floatbowls, and see if there is water or grunge lurking.

Its also not too difficult to try a separate battery to power the starter, although obviously you need a good battery (car ?) , and some cables to allow this.
Be careful that the connections are correct + or -, and shielded so can't short anywhere or anything. Only the heavy cables for the starter need rearranging.

Can you switch the coils around to see if the problem swaps side. ?
If you don't have leccy ignition, have you tried removing a plug lead and trying to start the difficult side only ?  This can sometimes identify where the trouble is, by getting everything spot on. This can be as simple as a throttle cable (or choke) not quite engaging enough to give a good starting setting. (Are the throttle cables perfectly synchronized ?).

Hope this helps.
