Cool runnings
So I went out for a short ride on Saturday...
... and the thing was running rough - slow tickover, stalling at junctions, slow pick up. The air temp was 4 degC and the water temp didn't get above 70. I stopped to use a cash til and left it running so that by the time I got back on, it had got to 85 and was acting normally. Two minutes of riding and it had dropped back to 70 and acting up. I guess the mapping it quite temperature sensitive.
Question is: Is the thermostat stuck open or rated too cool for the conditions? (Yes, I could take it apart & stick it in the kettle to check but don't fancy it)
