I have just bought a Hebo which I have initially tested, but not finished fitting as I have been too busy. So no pics ! I know some rev counters have given people problems, but this one seems to work fine so far.

It does have a temp sensor as well, and you can get the correct LMA 19mm adaptor for this from Demon Tweeks (LMA 103/E)
