Got very excited last Saturday when the call was expected to go and collect my bike....at last

 only been ....what a month

 anyway got the call but it was bad news, bike still running like a dog so no bike for me
   Got another call on Monday informing me it may be a bent valve??How could this occur then given the bike was running reasonably well the weekend before I took it in the shop.  Everytime I stopped at lights etc it stalled but as it was running a little rough since fitting the Db killers and removing them I took it to be Co2 or some such issue.  Not the case after MR worked all day Saturday changing bits to eliminate them; they were still no wiser.  So engine to be stripped and check for bent valve and I guess any other damage

  Hopefully DUK will include this if it is found to be the problem otherwise Christmas is looking slim this year.
