MMMmmm! Having viewed the guts of an Enfield Classic with ECU, CDI and EFI on the right hand side of the motor, I am very wary of throwing money their way. Less than 10,000 miles on the clock and it appears that the ECU has gone phut (£300+), or the CDI trigger has let go, even though its resistance is still OK. But, and it is a big BUT, you cannot measure the air gap between the trigger and the outside of the alternator, which carries the timing 'knobs'. As the trigger is mounted in the outer case, as are the alternator coils that prevents making these measurements!

Some of the corrosion on the wiring connections appears to be hampering diagnosis, I shall keep an eye and ask a few questions to see if and when a cure is diagnosed.

A Himalayan has been on and off my radar and I have been led to believe that the electrics may also be a potential Achilles heel.
So I shall continue my re-wiring of the 450 and see if I can make those electrics reliable.
My regards, Bill
