had the bike booked in at dealers again, didn't feel it right to let them of the hook and have to pay someone else to put it right. 3 days before it due to go in it started to work fine. spoke to the dealer who admitted they had done nothing the first time it was in
No point taking it back if they not going to do anything. fires up first time every time now and i have no idea why. fingers crossed it stays that way.
