Thanks for the responses. In reply to a few of the points raised; it was Experience who suggested that because my bike is an Airhead & their mechanics are far more knowledgeable on the Oilheads & newer bikes, their recommendation was for me to take it to the gentleman in Glenfield, mentioned hereunder. I did do so & as stated previously, was singularly unimpressed with the result. I must say that I have been riding, servicing & tuning my own Bee Emms for the past 40 years or so. However time & other constraints at present preclude me from doing so at present, hence my looking further afield for someone knowledgeable & competent to do this for me.
