Bring back magnetos and acetylene lamps

I thought that John untill we got the opportunity to ride a little faster, got the engine up to 3500 rpm and still no change untill the temp gauge started to fall and then a steady 14.2 volts, this was to be repeated throughout the trip.

If the battery was low it would take time to get back up to 14.2v
It would not happen instantly.
At a guess 10 minutes or so

And judging by the state of the roads Simon the man with the red flag wouldn’t go amiss, I’m thinking of swapping me tyres for knobblies .

So am I right in thinking the heat won’t be generated so the the cycle of heat/resistance is no longer a problem, also are there any long term consequences to the shorting process you mention.
Forgive me for appearing a bit thick Bill but primarily I’m a nuts and bolts man electrics are the work of beelzebub as far as I’m concerned, but from what you’re saying it may be a solution to what seems to be an endemic problem with the Bird.
What do you think?

It is under-rated for power imho but to solve the problem would be a very major upgrade of the alternator. Not really feasible. It is a very old design and perfect in so many ways. Change the battery regularly and if you are stuck in very heavy traffic on a hot day then pull over and let the bike cool down. Or buy a carb bird.

It. Was often a game of Russian roulette for me…watching the temperature gauge go up, knowing I was going to have to stop somewhere to let it cool down…and crossing fingers that there was enough left in the battery to start it….. always tried to stop on a hill!

Mine only ever gave me charging circuit problems at the time I used heated inner gloves.

Once I sorted it I dumped the heated gloves and never had further problems.

running a 30% larger rad for several years now. last year, in 45 degree C heat in Spain, it ran absolutely fine. I have never had any problems with cooling.
But then I am running a carbie

Running a normal Chinese rad for a few years now, no problem in 39°C heat going through France last year. I've never had any problems with cooling because I have an FI and I know a coolant mix in a sealed system doesn't actually boil over at an indicated 100°C, because I'm not retarded.

 

[Oldandbald]

Agree with the first bit. No comment on the second bit.

How is it 30% bigger?

 

[andyBeaker]

There's no way I'm dumping heat from the sink to me bollox.

Don’t knock it until you have tried it.

It has a thicker core, need to let out the front V panel a bit but it fits fine.
