One last thing a couple of members (including myself) have had is an intermittant shutdown in the lower to mid range throttle positions. It felt similar to hitting the rev limiter. I disconnected my TPS sensor and no more problem. When I checked the sensor the variable resistor was messed up. The resistance values are found
here at Triumph Twin Power. There are no real problems running with it disconnected. Good thing to check. Mine has been disconnected for a couple of years.
