I just purchased a Fz1 street fighter. The bike will cut out under a load for a second and then be fine. It seems to happen around 4500 rpm. The bike has a brothers juice box ficm. The guy has tried to fix this for while and can't. I'm thinking of replacing the ecm. Does this bike have a ecm and a fuel injection module? The juice box is directly under the seat. Where would the ecm be? I'm thinking this problem has to be a electronic concern. Any info would help. Thanks
