    While idling, bike flashes back and fourth from R to N several times, then burns the ecm, wtf! As these are not cheap, and this is the second one, I thought I'd ask for suggestions before putting the new one on. Will idle for 10-15 minutes just fine, when I give it throttle, boom RNRNRN then burns ecm. Please help. Thanks all
