I have a 2014 YZ 450 with 14 hrs on it, it is all stock with the MXA richer map . A few weeks ago, (at around the 10 hour point of total bike ride time, bike still near new), the bike stalled just at the base of a third gear jump face and spit me off, needless to say it was an ugly crash. It had occasionally been popping and farting but this was the first time it actually died momentarily. I thought this crash was just an bad fluke, so I repaired the crash damage and iced my knees hoping for better luck the next time. Well it has now done the same thing 3 more times...unexpectedly stalling resulting in a crash. Expect for these random stalls the bike starts & runs great. As you can understand this has totally ruined my confidence with the bike. I run clean 94 octane gas and maintain the air filter and engine oil religiously. Anyone else had the same experience with the 14 YZ450? With the complexity of these new machines, can anyone offer some incite as to which FI or ignition component and/or parts could be defective causing this issue. I really need help with this.
