Although not needed in pool's situation, I would think a clever fellow could devise something that would function for someone who was disabled. And it would be relatively cheap.
Lets say one was willing to give up the space where the passenger would sit. An electric motor could be fitted, with a chain to another sprocket on the drive wheel. Another larger battery would be needed, perhaps. But another alternator charging system could be in line with this chain. So that the battery charged not with engine speed, but rear wheel speed. The bike could be placed on center stand for starting. I suppose the counter weight needed to keep rear wheel off the ground would be problematic. Certainly less than even a light weight passenger.
If used just for starting the weight of the unit, should not be excessive. I suppose one could bump it up to provide actual emergency drive power.
I am sure there would a loss of HP available, so not desireable unless necessary. Would also be unsightly. But it should work. And with the new emerging technology for hybrids, power from braking etc., and better lighter batteries, it should be doable.
You REAL name is Rube Goldberg, right?
May as well just buy a QPD setup. Far better solution.

Without going to the dry primary it appears the starter installation would require a new clutch with ring gear (no point in wasting time with the stock iron unit), sprag clutch drive, primary cover and starter. You could weld on to the existing cover but that would not be a bolt-on installation. One of the expensive parts is the sprag clutch needed to turn the clutch and disengage the starter. The units on car starters are only meant to overrun on starting and not continuously. It looks like a unit from a Japanese bike would work but it still costs $215, plus about $70 for a planetary gear starter, Norton Commando style alloy clutch with plates and ring gear, primary cover - you are looking at at least $1000. Then you need to add the battery, cables relay and start switch. Worth it?
Hi, yeh it looks like it would be $1000+ for the type of work mentioned. For the moment I think I will go with the mechanic doing what he can to try get it kick easier without the the big job of button start. BUT at some stage i will have to get it done in the future if it gets harder, rather than give up the bike.

Early in the thread, Nick had/has the right idea. Put in pistons with a lower compression ratio...it would also go a ways toward toughening the motor against detonation with the crap they sell for gas nowadays.
While you'd probably have to farm out getting the cylinders honed and measured, with the help of this forum you could do the rest yourself!

Fitting round pegs into square holes since 1961...
How much space is there between the primary cover and the peg? I sketched up an idea using a machined spacer between the stock primary cover and engine. The spacer holds the drive gear for the clutch ring gear. You would still need a Commando style clutch as the wobbly A65/T140 clutch would be bad for gear engagement. The only engine modification would be longer primary cover studs or pillar extensions.
