I have been running without a working Ex-up valve for two weeks now. Aside of the rev counter jumping from 0 to 7K and my gear indicator not working because it runs from the rev counter, the bike is seriously down on power, it uses loads more petrol and the valve has now started to rattle on start up. Hopefully all sorted this weekend (if the servo motor turns up in the post Grrr)
