You could try one of these, you do need to get one of the program boxes which can be a bit hit or miss as to if they are in stock but I've just put one in my H2 and it's awesome.

Also depending on if you want to do club or brca events you could try one of their motors too.

You can get the speedo, motor and program box for around £60.
