Hi Mboddy

The starting problem has been very random, twice it has not started from cold and has resulted in it going back in the van
and going home. On other occasions if the bike has been stopped or stalled it takes an age to fire up. What makes this hard to put a finger on is that it has run perfectly on other days. I am going to sort the old ignition and see what it behaves like.
Did your bike fire up when it was dried out ?.

The next step will be to get some figures from Powerdynamo.
I had a look on there website earlier and they are showing a much reduced catalogue.
Powerdynamo itself has shutdown due to the health of it's owner.
The manufacturer is VAPE and they have taken over sales now.
The IT200 ignition has been discontinued.

That's interesting but would explain the reduction in catalogue. Not sure where that will leave me with getting any info out of them. I suppose when I have the original ignition working I will have a better idea weather the Powerdynamo system has a problem. Did you get your bike running again with the 12v set up.

I got it running again. But not at the event.
There was deep water at Harrow and some got in via the warped ignition cover.
Previously with other manufacturers ignitions, I have found that problems are most likely due to water or heat or bad connection/earthing.

I just re-read your earlier thread and did not see any reference to what plug and plug cap you are using.
PowerDynamos are known for starting issues if the resistance is too high.
I always used to use the NGK 5kohm plug caps before I got the PowerDynamo.
Now I use the Beru plug cap that they recommend with a non-resistor plug. Leads are as supplied.
What plugs and caps are you using in both your and your brothers bikes?

So,
Back to the hard starting with the factory ignition.  My '81 IT465 has never been hard to start.   I'ts never been easy to start, but that's 'cause it has a big ole piston in there.  I've had more starting issues due to the petcock not shutting off completely while hauling it to a ride.  As it goes down the road the carb needle bounces up and down flooding the crankcase 'cause i'ts being fed a steady diet by the leaking petcock.  I now have a new petcock, I run it out of gas prior to loading and I unhook the fuel line to the carby.  Starts in 3-4 to four kicks at most upon arrival.  Then it starts in 1-2 kicks as a rule hot or cold.  A good working factory ignition should start fine.

HPI is another option, they list an ignition system for a yz465 which has the same part number. They may be able to tell you the advance curves, but better to phone.
