Hello guys, I have spent several hours searching for solution of my problem but I ran out of ideas, maybe somebody solved already the same issue. My Hayabusa is year 2000, 40,000km, everything stock. One morning after cold start it seemed like going on 3 cylinders, after approx half minute everything got back to normal. I thought about faulty sparkplug. On the way home (200km) I felt on the highway low power and when I slowed down and accelerated at low speeds the engine was stuttering like hell, I nearly did not get home. What is strange when reaching 7,000 revs it runs like hell with full power. I already tried:
- changing sparkplugs
- changing gasoline for Shell 100oct
- checked fuel tubes
- checked air temp sensor
- fuel pump I have no measurement but I assume that if it would be faulty, it would not give enough gasoline in the high revs and not in the low revs
- checked compression, I have 9,5-10 on all cylinders
- turned the throttle sensor (on the left side), in one position I even did not get the bike from the idle, another position was quite better but still by giving full throttle it stutters
- error code C00...
When I start engine without airbox and get in revs, I can see little flames comming out of the throttle valves..
the bike had always full service, approx one year ago were clogged injectors and cleaned, since this running without any problem. What do you think could be this thing? My assumptions are that if fuel system is faulty, it would not run in high revs (from not having enough fuel), and if the engine would be gone it would maybe make some noise of give warning before? I dont want to believe that engine dies so suddenly without any previous symtoms..
thanks for ideas, I get desperate...
