2005 ZZR 600. Starts easy with the choke, or without once warm. Idles a bit rough but still runs. Idles smooth and high (5000rpm) with the choke.
Symptoms:
The moment you touch the throttle it wants to die. At 5% throttle it dies, if you go from 0 to 10% and hold it, it very slowly picks up and then revs if you give it more throttle. If you go from 0 straight to 20% or more it dies again.
Hooked a vacuum gauge up to the carbs, bounces around like crazy at idle. From 0 all the way to max and back with each pulse
Checked the spark/coils, looks good and throws a nice spark
Suspecting bad valves or head gasket due to the crazy vacuum gauge readings? Don't suspect a carb issue as it was cleaned last year, and the symptoms don't quite line up from my experience. Any ideas?
Don't wanna have to drop the engine to access the head gasket or valves without knowing for sure if they're the issue. Thanks!
