NT700 Throttle position sensor investigations

I investigate the possible causes of the alarming power surges on my NT700 (Deauville) which lead to a dangerous 'bucking bronco' type ride! I test the TPS 'insitu' and then locate and clean up all the connectors from the ECU through to the sensor. I also offer some observations on valve clearance (tappet) adjustments and on a coolant change in passing! Once complete the bike runs nicely (but I will update this post if the problem comes back. Only time will tell!)
