Yes getting older presents a few challenges. I'm lucky that (heading into my eighth decade in a couple of years - wow) I can still start and ride and maneuver bikes around, and get a lot of my enjoyment from researching and fiddling in the shed. I have to admit that I do lots more riding on my ebike than I do on old bikes these days, and I do the riding off road to minimise the chances of being cleaned up by increasingly dangerous traffic.

I was going to suggest starter rollers as a solution to your starting problem, but getting the bike on and off the rollers has so many opportunities for disaster that it might be best avoided.

With new knees, have you considered an ebike? If you have low-traffic places to ride near home it's great fun, and - if what I've read is correct - good for knees and general health. Mobility is such an important part of our lives.

Must be frustrating, though, looking at the that little Fanny B... dream machine!

Practice your run-and-bump start ?
Its generally easier to kick over a bike once its warm.
Well tuned, they practically start themselves.

Hmmm, so thats why LE Velos are becoming popular again..

I was toying with the idea of trying to fit an Enfield decompressor but there's not much head to play with. Someone suggested a larger engine sprocket and that might be a way forward. It's demoralizing to get old, I even tried my  FB with the 196 super sport, but same thing, can't get enough momentum to get over compression. Might be some  exercises that'll built up the leg.
Cheers,

Pity the blipping thing doesn't have a valve lifter!

The bikes an easy starter for everyone else, so it has to be my decrepitness. After riding big singles all my life, you wouldn't think a year off would weaken the leg so much. I've put an electric start on the goldie, but can't manage the weight yet. Perhaps I should finish the hand start LE Velo. Thanks for your input.

No, sadly it won't make any difference.

I assume the piston has a high dome. You could either change it out to one with a flat top, or put a decent spacer - say 1/8 or 3/16" - under the cylinder. The only thing to watch out for is that the combo of the pushrods and valve adjusters will accommodate the change in height.

Have you enlisted an enthusiastic kicker to start it up?

Good luck!

Heading into my ninth decade and recovering from two new knees, I been off the bikes for over a year. I thought I'd start small so dug out my tiger cub to help build up the leg strength again. I can't even kick the cub over. Tried the usual tricks, thicker head gasket and longer kickstart but still no joy. Other than drilling a hole in piston, I was wondering if retarding the valve timing one tooth might reduce the peak compression allowing me to get it over. I realise performance may suffer but hopfully it will only be temporary until my strength is back. Do members think it's worth a try ?

Hi Ramwing,
Yes the pressure required to fit the fixed gears to main and layshaft varies just as you have found
Only thos evening I was changing a layshaft gear to another shaft, luckily they were not too difficult
