Hi
I think your question would be better answered on one of these forum

Hi Johnny,
No, that one is for a dynamo equipped motorcycle
One of these will replace your existing plate rectifier, but you are still dependent on the old switching of the alternator coils for crude regulation

Here is an ebay link to 6v rectifier regulator units for alternators
These are a better option than the switched output setup originally fitted

Hi,
I would try and contact the VMCC Calthorpe Marque specialist via a message to the VMCC, and or a message to
Old Bike Mart (monthly vintage bike paper) who publish such requests

Hi Oggers,
Make sure to follow the manuals instructions for positioning the crank/cam before you adjust the tappets

Correct main jet size is dependent on several different factors, it can vary from one bike to another
and on fuel available, exhaust type fitted, air cleaner type, atmospheric pressure, altitude and more
It can be sized by road testing or better again on a rolling road diagnostic
Remember too lean and you risk piston damage or seizure

Hi Oggers,

Needle jet is 220 on my 930 Amal concentric.

Something wrong there??
That sounds like the main jet number ?
You need to remove the part the 220 brass jet screws into and the needle jet is threaded into the top of that
Likely it will have a number like 106 on it
These jets wear and so do the needles, these govern the mixture approximately from 1/4 to 3/4 throttle
so have more influence than the main jet except for WOT running

Hi Moleskins,
Do you pull in the clutch lever and kick through the kickstart lever a few times to free the clutch before you start the bike?
Its a Triumph ritual, I kid you not
10/30 motorcycle oil for me in the primary (suitable for wet clutches)

Hi All,
Going back to the original question,
There are lots of shit sockets advertised as WW on the net, they are nowhere near accurately sized :o

Try and find proper WW size spanners and sockets from known brands
Search ebay, autojumbles and car boot sales for secondhand Britool, King Dick, Gordon and other UK / German brands

British Bikes / Re: JAP engine number
« on: November 30, 2018, 08:21:20 PM »
Hi Paul,
That about sounds right, if the engine fits in generally with a 1929 appearance,
twin port would be a style of the times
JAP offered several style options on basically the same engines, (different finning shapes and magneto chain case lengths and placements or maglita driven from the drive side)
The year codes ran from September to August according to my JAP book which can lead to "discussion" when it comes to Whats Vintage???

Remember that JAP reissued the engine year code post WW2
This is why lots of late industrial engines that appear for sale are mis described as "vintage"
Usually the SV engines from the earlier period had cylinder and head as one casting

Hi,
A side on photo should help id the tank
The fliptop filler cap and breather in front of it suggest ZB BSA GS,
the front mountings that take the rubber inserts also fit
But!!
I have not seen anything like the rear mountings on a BSA before

Hi All,
For those interested the Scott and sundry S7 bits made 6,000
The BMW went to 26,000  :o :o ::) ::)
The Matchless made 12,000,
I thought the Matchless would have made a bit more ??? taking into account the value of the Vincent front end ??

Hi m-m,
Are you trying to throw us off the scent so to speak?  ;D
The Scott and S7 are lot 420
http://www.biddleandwebb.com/lotdetailzoom.cfm?auctionhallid=3&saleid=517&itemuuid=ACF0AA5C-C19E-2008-ADA1E9AF347AC33E&item_imageid=360271

The Matchless with Vincent forks and the BMW in the previous lots should be more in demand ??

Hi All,
Going OT here somewhat

Allegedly the quick and dirty way to tell a JAP bike engine from one from an industrial engine is the bike crankshaft will have a tapered crankshaft for the drive while the industrial unit will have a parallel keyed shaft.

Not always the case,
Usually industrial engines will show some evidence of a cooling fan or shroud mountings and quite a lot have either extended crank or cam shafts to drive the cooling fan or for a starting handle

I visited the so called "National motorcycle museum" in USA a couple of weeks age where I saw a JAP 600 industrial engine labelled "JAP from the Teens", (it was more than likely ex Howard Gem rotovator as it was identical to one I have) .. The person in charge was happy to take note of the correction I offered   ::) ::)

Hi,
It wasn't the adjustable mag sprocket that gave trouble, even thought it was blamed initially, the points rotor screw
came loose and the rotor pressed key "unpressed" to let the rotor slip,
It became apparent quickly that evening after the original sprocket was refitted when the bike fired up and died almost immediately with no spark,

,just making sure nothing comes undone or falls off........

That's the lesson learned by the owner /rider   ::) ::)
