It does indeed go to 11

I took Minnie down to Dynobike this week after I had some time to fill in due to a no show, which went rather unexpectedly very badly.

It appears Minnie is inhabited by some sort of poltergeist, the kind that enjoys messing with dyno control systems.  The inductive pick up, used to read engine speed, was registering (albeit not accurately enough to be useful) that the engine was running while being a metre from the bike.  We tried some non rpm runs, but the air/fuel readings were going nuts and occasionally the screens would drop out.  And then the dyno decided it was too cold.

We did get a couple of "power vs rear wheel speed" runs, but because Minnie doesn't have the tacho fitted, I really don't know how many rpm she was doing.  I did see that Dave had already had a couple of M400 in.  One of them, labelled as a 2003 so it may have been an ie, put down 37hp at 11,000 rpm.  I had assumed that the claim of max power at 11,000 rpm was rubbish, but it would seem I was wrong.  Again.

So, first dyno chart for Minnie as a 400: 41hp.  I'm looking forward to getting the tacho fitted so I can watch as I ride.  I'm pretty sure that I haven't gone over 7 or so as yet.

As an indicator, this is the 2003 model with rpm.
