You could remove the case to check that the level screw has a cutaway for the oil to issue.
Could be blocked or the wrong choice or screw or wrong outer case!

My C15 starts cold first kick every time without fuel on, choke, or tickle.
The throttle stop is screwed up to a known position.
With engine hot, the stop can be lowered.
To start hot, it needs throttle open the right amount. Too little = nothing. Too much = kickback.

My C15 SS has the needle fully down on the slots.

You  should be able to find the Rupert Ratio book on Ebay.

Singles / Front brake
« on: 20 August, 2017, 07:00:53 »
I was at the Stilton bike show yesterday, met a chap with a B44. We chatted about brake power on british bikes.
He had twin leading shoe conversion, But I was happy with the standard brake on my C15 SS.
This has reminded me of a conversion I did 50+ years ago.
My B33, with Superocket engine fitted, had the standard, one sided drum.
I had noticed the way the Vincent twin front brake worked.
I bought another wheel from the breakers ( About 3 ). I removed the press-fitted drum and the short spokes and fitted them to my wheel.
To work the twin drum brakes, I run the original inner cable to its normal brake arm on the right.
I shortened the inner cable, and fitted it to a home made alloy sheet lever, pivoted at the centre, with another inner cable connected to the left side brake arm.
This gave the normal action to each brake, with normal pressure on  the hand lever , but needed twice the movement.
So the only disadvantage was that the cable needed tighter setting, and more frequent adjustment. It worked perfectly well.

I dont like the heavy cast iron, full width hubs on my C155. I would like to the lighter slim hub type. It is the high cost of spares that stop me!

I cant see a number on the carb.

Mark,
I want to drive at normal road speeds - 60MPH, 70 MPH, even 80 MPH.
My bike reaches 60 OK. 65 takes awhile. 70 is rarely possible.
I would like 80 or more to be available, so overtaking is safer.
I ride FLATOUT where the road allows, that is because the bike is so slow!
There is NO problem with running at full power.  It is needed with any low powered bike.
If I had plenty of power I would not need to ride flatout!

I know a Japanese bike would give me the performance, but my desire is to have a classic British machine.
I do not have the physical strength to handle anything heavier than 300 lbs.
Cost is also a consideration. My riding is only local, its a problem thinking of anywhere to go!!

I think I have reached a plateau with my C15 SS.
With the 18 tooth sprocket, it needs clutch slip at take-off, or in slow traffic.
Did a flat out speed run. 66 mph one way. 71 mph coming back.
With the previous low gearing, it was no faster.
At only about 5400 rpm, it is more pleasant and less strain on the engine.
At full speed on full throttle, when I ease the throttle back ,there is no loss of speed until nearly down to half throttle!
This suggests that the 1 1/16" carb is bigger than needed. It would be interesting to try a 7/8" if I had one.

8.5/1 comp ratio, scrambles cam, bigger inlet valve.

There are plenty of photos and drawings of the gearbox on line.
You could search Google images with various wordings.
There will be sumthing to help you somewhere.
Also, the 'draganfly' spares site has illustrated parts lists.

The Star and Garter / treating rusty rims.
« on: 03 July, 2017, 16:53:24 »
My C15 has many small rust spots on the rims.
Rubbing down with wirewool removes most of the rust, leaving very small  spots.
I will try rubbing over with a rag soaked in silver paint, to disguise the spots, and give some protection.
Is this a good idea, or is there a better way.

A quick fix so you can ride again. drain all the oil from the forks, carefully clean all traces from the outside.
Put the oil back after MOT.

This morning I changed my rocker box gasket. Bad leaks from top end.
I tested my top speed. Now 66 mph at only 5300 rpm, not the 8000 rpm
'red line' for this engine. Much more pleasant.

My C15 SS came with 15 tooth sprocket. As used on C15T
the standard for C12 SS, is 16 tooth.
For C15, 17 tooth.
I have now changed to 18 tooth.
I like it!
More relaxed at higher speeds. It still moves away from rest easily, and has lusty acceleration with a handful of throttle.
And that nice bang bang sound of a big single.
