All reassembled with the non yamaha bearings and all looks well. My local yamaha dealer also gave me a bit if discount on the 6 tubes which then came at �66 all in,and we're here in 3 days.
Weirdly I originally tired aj sutton before Christmas for the tubes and they told me the tubes would need ordered and not due until the end of January ,fowlers also telling me the same sort of time frame,and both were dearer that my local original price quote.
