I can't Figure out how to add or post anywhere else I figure I would do it on here first off this forum is great. I've been reading through it for a number of days and you guys must really know your stuff and are very informative. However my 2011 DS 450 xxc is not starting. It does a half of a really good start and then dies down then goes to a good start and then dies down new plugs new wires new battery valve adjustment was just done cam chain and tensioner replaced. It's in the shop right now my bill is already $1,000 and they don't know what's wrong with it either. They're out of ideas as am I. Any help?
