I dont think the very small increase would help much, and it would need running in. I dont have time for that at 80.
(Your only young twice actually!!)

Thanks Derick for the link, but i dont know my bore oversize, and I think my piston is already high comp.
I will find out when i take the top end off.

To me, the whole point about riding, is recapture my young days, 55 years ago, when there were no Jap bikes.
My C15 loves being driven hard!

I thought I could avoid the cost of a new piston, and upsetting the balance of the engine.
I sold my B44 because of high vibration level.
I just did a quick run round our March bypass. (my usual blast)
Only just manages to pas large lorries doing about 70.
Two up would be worse, but unfortunately my Tart ( Sweetheart (wife)) will not consider it!!

Singles / C15 compression increase
« on: 15 November, 2018, 07:47:35 »
My C15 ss has , (I think) 8 1/2: 1 compression ratio.
If I skimmed the barrel by 1 mm, would that raise the C/R to 9:1?
Bore is 67 mm. stroke 70 mm. My maths is no longer good enough.

Would this be a good idea, for more power, but still nice to ride and start?
Would Higher C/R be worth trying? I could always fit thick gasket to take the ratio down again.

I took my C15 SS output sprocket down on more tooth, now 17 teeth.
The bike will now reach 80 MPH at around 6800 rpm.
I am pleased with this

I had a B44, which was a C15 with the bigger engine. Same weight, (I checked it)
B44 reach 90 mph, but always had quite a bit of vibration.
I decide it was too much and sold the bike.
My C15 SS is much smoother, and will reach 80 mph in favorable conditions.
The B31 was a much heavier machine, 100 lbs more.

contrary to what I said above, the B44 was not pleasant to ride above 40 MPH, or equivalent RPM.
I have sold it, and will manage with the slower C15 SS. (80 MPH on a good day)

Thank you for the link,, but-
Its too expensive
It looks far too slim to fit round my body with heavy biking coat, and thick inner lining.
I have ordered the 1.50 one on Ebay. I dont mind cutting that around to suit me.

I noticed today that my helmet peak was missing. I was ok without it.

the seller of the small flashing lights is candy-fly89. item. 332732902641 1.54.
I have a yellow jacket, but it wont fasten at the front. I must make some ties or straps.
Better - buy a bigger one. But where?

The Star and Garter / emergency braking
« on: 28 October, 2018, 08:23:11 »
I have recently  had near misses at low speeds, when cars emerged from side roads right in front of me.
Each time I managed not to hit them.
I wonder if I used both brakes in that panic moment?
I remember several years ago, when I started riding again after a 50 year gap,
I made a point of always braking with both, so that it would be automatic in the panic moment
when a crash might happen.

What do YOU do. (apart from never getting into that situation)

The Star and Garter / bike near misses.
« on: 28 October, 2018, 08:13:56 »
Riding my C15 in heavy traffic through town, I have had three near misses.
Each case the same.
As the stream of traffic passes a side road, a car pulls out suddenly. right in my path.
Each time i braked heavily, skidded the bake wheel left and right, then recovered without stopping
and feet still on the pegs (Old trials experience)
I guess this is caused by the offending driver, seeing a break in the line of cars, dodges through quickly,
not havingnoticed me on the bike until it was too late.
It has often been said that bikes can sometimes be invisible to other drivers, being quite rare on the roads.
To make mine more obvious to others, I have fitted a pair of flashing LED lamps beside my headlamp,
one above the other  (side by side might look like car headlamps further away)
These lamps are visible for 100 yards away, or more. Cost 1.54 including post, on Ebay.

I bought 2 inch LED lamp, with four LEDs, each with its own reflector in the 2 inch housing. cost was very low, Less than a fiver I think.
Finally fitted it on my C15, crudely on a bracket from the side of the headlight.
What a transformation!
Instead of a dim, yellow splodge on the road, (30 MPH max), a BRIGHT, white beam, lighting up the road well ahead.
I feel I could now ride confidently at night.
(Not that I ever want to right at night!)
