Tanis, I'm going off my 8 years of owning these bikes. Not saying it can't happen, as it obviously did to you and someone else in that thread. But, in my experiene these engines have been bullit proof. My appologies for saying "don't listent to this dude"....and that you probably hadn't owned one. Mine are also 400's not the 426, so maybe something changed in the newer generation. But still, reading through this thread, the majority of poeple have had good experiences with the engines.
