I am hopeful the issue is ECU going back to "new" but nothing is ever simple with our machines so will keep looking to other possibilities

To that end I have taken battery out and had it checked at battery shop. Clean bill of health on all accounts . So cross off battery, HT leads and sparkplugs.

At this time will look to get the hours up to get to "no rev limit threshold" on ECU.

Whilst doing that, will also look to source fuel filter. Fuel pump sounds strong at turn on of ignition .

In the mean time the weather is magnificent and very unusual at this time of year. Some starting to complain of the lack of rain!

If xmas dont get in the way, should be able to do the 2 hours needed to fool the ECU.
