Hoping one of you guys can help me here.
Ive been trying to get a friends hayabusa back on the road. It was running perfectly but then sat in the shed for Years, when he came to it the fuel had gone off and turned to jelly.
Anyways he cleaned it up and replaced the fuel pump internals as the bad fuel Ruined it.
The problem im having now is that the bike appears to be running fine until you take it out it pulls well but as soon as you roll Off the throttle it dies, flick the kill. Switch, hit the starter and it fires up again before youve even rolled to a halt. It ticks over fine and pulls through the gears on the stand but cant be ridden .
The bike is showing no fault codes. I have done basic resistance checks on all the sensors and nothing has come back odd, i put a fuel pressure gauge on the rail and found the pressure running anywhere between 60psi and 120psi which seems very high, the bike ran better when I got the pressure down to about 45 but i dont know what it is supposed to have when its running.
Ive had fuel pump stripped and and fuel Rail off and put it all through the ultrasonic cleaner. Put it back together this week and tested it out today still exactly the same. Seems to run fine but didn't get half way down the street before it died on throttle close.
This thing was perfect before it was stored but now its driving me mad.
Does anyone have any suggestions what might be causing all this?
