I'm presuming you have the blue ignition system?

If so, you have found your problem.

Having done some experiments with the blue stators I cannot believe that a simple piece of eqipment can have such huge variations in its performance with just a change in humidity and temperature.

Having monitored the resistance of the windings between -4C and 60C, I found they varied anywhere from 145 ohms to 238 ohms.

That nearly 49% variation.

One coil I measured varied 62% over the same temperature range.

That is a massive variation and would have an adverse efect on what the coil unit sees as a viable signal.

The second winding is I presume the trigger coil and is of such low resistance that there is no noticable variation.

It could be that a hot air gun carefully applied on the stator could cure your problem but that doesn't help when you're on the grid all alone.

I'm at the musing stage of building a test rig for these things but essentially it need a complete redesign.

Iame or derivitives thereof, refuse to answer any emails so I'm very anti X30 at the moment as it's ruining the class.

Customers deserve a definitive answer and that certainly can't come from the Iame 'electronic expert' who actually must have spent his holidays at Sellafield as he was 'talking' complete b*****s.

The old black electrics were fine so long as you had a good short period cold cranking battery.

If the battery was at all weak, the cranking voltage would drop below a level that would allow the ignition to supply a spark.

We used to start the engine while piggybacking another 12volt battery into the loom and the engine would start every time.

We never changed over as I knew it was a bad design so kept the old black system.

I have no doubt people will be forced into changing over at some point and at that juncture I will probably walk away from karting and join the WI, quoting equal rights for men, but I will NOT be doing any future calendars!
