zx7r 97 hesitation

12-03-2018, 02:04 PM
Just like to say hello to everyone! I have a ZX7R 97 with a hesitation between 5,000 and 6,000 revs, it feels like no fuel or a electric cut out, runs perfect to the 5,000 and above the 6,000 revs, it starts fine. It has a K&N air filter, an after market exhaust, the sparkplugs are slightly black, it had the valves checked about 4,000 mile ago due to a camchain runner being replaced by a bikeshop. I have changed a fuel relay, fuel filter, coils and sparkplugs. Any ideas what I could try next???
