Identify these bikes! / Re: Need help to identify this engine
« on: September 14, 2012, 09:06:14 AM »
What a pretty little engine !
It does say JAP on the drive side crankcase ?
Firstly, JAP mostly used a fairly complex series of letters to identify their engines, and any special features. If you can find a (possibly long) series of letters anywhere there, it should go a long way to identifying it. If it has numbers, they will give an indication of year.
2ndly, looks 1920s, more later 20s. Someone has done a lot of work fitting quite a sophisticated looking oilpump, and presumeably oiling system. Subeam engines usually had a Sunbeam badge inset into the timing cover itself ?
That Amal sidefloat carb looks decidely later. Likely to be quite a good performer because of it...
See where we go with the numbers/letters to give a year ??
JAP supplied literally dozens of manufacturers with engines, so pinning down a precise make it was fitted to may sometimes be somewhat problematical.
Cheers.

British Bikes / Re: oil pressure gauge wanted for 1938 triumph 6s
« on: September 13, 2012, 10:12:35 PM »
When you find the person specialising in rebuilding these - there will be someone, triumphs are too numerous for there not to be - they will likely have had some new faces screen printed. This makes essentially a new gauge out of it.
Low pressure gauges were also fitted to some Ariels, and a few makes of cars, so somewhere there will be a supply of them... Hopethishelps.

MEK (methylethylketone, type of paint thinner) is commonly used to dissolve/strip out old tank liners. Ditto, keep it away from your tank paint.

P.S. Before getting it rebored to remove the cylinder scoring, have a close look at what the piston is like and how thick the cylinder walls are - it may be a lot simpler to get it resleeved to suit the present piston, if rings can be found and the piston is serviceable. And it will keep the cylinder walls stronger, engines back then tended to have thinner walls, not always conducive to lotsa rebores...

Interesting story and interesting pic then.
Could well be right about chopped down forks, although the Dayton had forks like that (heavier though, & pivotted in the middle), with Deluxe engine for 1915. Without the tin can at the top though...
The Deluxe engine in a Deluxe motorcycle came from 2 different makers - Deluxe engines were built by Spacke (Indiana) from 1913 to 1917, supplied a number of makers - all near clones of each other. So could be in a Deluxe, Dayton, Eagle, Sears, etc ? ( i.e. you can't tell its a Deluxe motorcycle just because its got a Deluxe engine in it...)

If you can get it running as is, you will probably find that BSA folk of the 1930s will be keen to get a look at how many minor details were done, and what the finish was.
This is what largely disappears when bikes are 'restored'.
Early 1930s bikes are particularly uncommon, the depression stifled sales, and bikes of that era were commonly run until completely worn out.
A lot of BSA stuff was common for many years, find out what size and how the piston/rings look and later parts will likely fit.
C&D Autos advertise a lot of parts for older models...

Those Deluxe front forks/ action don't look anything like the forks on Keiths dads' bike ?

Look familiar ?
http://home.planet.nl/~leonhop3/1932_l5.jpg
Once all painted up, with all new parts and shiny and new, like all the other remanufactured similar, will probably be worth less.?
Remember, they are only original - once.
Exceptionally rare these days to see them as they left the factory...

Indeed - wise words.
Lovely bike too.
Source new mufflers for it (they are not with it ?), and ride off into the sunset.
Leons BSA website somewhere shows each model for each year - a google should find it.

British Bikes / Re: Clutch drag on 1938 Norton when hot
« on: September 02, 2012, 05:27:00 AM »Some of the chaps in the vintage MCC suggest doing an adgustment on the bolts holding the clutch springs in place but I've seen in the "Book of Norton " that they should be fully tightend. Would there be an issue with loosening them?
Are you reading that correctly ? They should be ALMOST fully tightened - but then adjusted so the outer plate appears to lift squarely and evenly. If one has a bit more or less spring strength than the others (not uncommon) then the plate doesn't lift evenly and clutch drag could well be the result. The spring pressure should prevent them from moving from where-ever you set them. HTH.

From a bit of googling on the web, it looks like these were rebadged Puch 250 machines, mid 1960s.
Its none too clear, but could this be one of the famous "twingle" engines ?
One cylinder immediately behind the other, as a split single, with 2 pistons for a single crankshaft - one does the inlet 2 stroke port, and the other does the exhaust. Quite a good design and performer, apparently, although a complicated way of doing things...

Dying when you give it throttle is almost always a blocked jet. or blocked fuel feed into the carb. (Provided the points are clean and correctly gapped).
If you try this with the choke on, does it change things at all ?

Good call on the Royal Enfield type frame.
A bigger/closeup view may also show if its prewar or postwar also, since they are all quite similar. Prewar and military is becoming quite collectable - rideable too, if not in a hurry.

"More than 140".

Thats rather a lot, when you tot them all up.
And not very specific - how many more than 140 ??!
