Thanks in advance for any tips..
So, 15k on the clock, ran fantastic up till and including its last ride a few weeks ago.
Today, started out running fine leaving on a 3 hour tour and about 10 minutes into the ride slowed to low RPM to make a turn,, slight roll on the throttle and got a buck/jerk. ..Only..
First thought was the wheel lost its grab, corner was clean though,, but repeated again after leaving the next stop sign. No issues with grunt and pulls hard n smooth right up to the top,, no FI light.
After a few hours it’s gotten worse ( can reproduce the misfire dragging the clutch ‘stationary’ adding in some throttle). Seems like it misfiring on more than one cylinder..
When it started the issue, seemed like only one hole was dropping out. Or was just a quick fart, then ran fine..
Plugs are still OE,, certainly a possibility and first check point, but given the rapid change in how it’s run in just a few hours, leads me doubt them. Fuel is clean, same tank as the prior ride when it ran fine..
Duplicating the misfire as noted,, it seems ignition dropout related since the mis is abrupt for the most part, clearly hearing cylinder contribution is lost and/or erratic.
Injector/s,, ignition, hard to tell.
It does idle a bit erratic, maybe a slight mis now and again, but RPM affected ranges are roll off idle to about 3k.. Anything after that, a bullet..
Any pointers or alike failures that the Busa’s enjoy?
