This is my 1st road bike & 1st time on any forum - swapped it for a KTM 525 EXC a Pom sold me the day he went back to the UK..2 hrs into the ride..cam chain busted caused AUD$4500- damage...so straight swapped dead KTM for this ZX10 '88 model, road licensed, rides ok but runs as rough as s***.
So, it's got 74000 k's on the clock, stock standard as far as i'm aware. Up to 3000 RPM, it splutters and pops out of RHS exhaust. Splutters more in higher rev range, getting embarassing.
Had oil/filter changed, air filter replaced too. It back fires out the RHS too when hot. Just bought some Irridium plugs from UK, hoping to instal soon to help with the problem [half price from UK] run top grade fuel, have put carby clean through tank, helped for a while, but back to s*** running again.
