The speedo drive on my Ascot was broken when i got it, ordered a replacement from a salvge company on ebay, recived it yesterday and it looked ok, moved freely and seemed in good condition. Installed it last evening, took short 1 mile test ride and worked well, on my way to work this morning got out on open road as soon as i hit 55 mph the speedo quit working, I'm going to assume the drive went again. My question, is this a common problem for the ascot or do i have a problem with the wheel end of the drive system. And is there any alternative speedo drives that work. I would like to keep the origanal speedo if i can. Thanks
