So I go out to meet up with the local IT guys from different companies for lunch. I take my 919. It's been running perfectly ever since I had that kill switch incident about a year ago. Let's not go there.
It runs like a champ to lunch, couple miles of city streets and a few miles of highway.
On the way back to the office, I take the exit from one highway to another, pass a car, and in 2nd or 3rd gear at about 6,000 RPM, it falls on its face. Spits, sputters, and just totally loses power. I roll off then back on the throttle and all is fine. At this point, I'm about 2 miles from the office.
Once I get within sight of my office, I take the street that runs next to it because it is desolate and straight. I'm going to try to re-create the problem. I get on it in first and take it to about 8,500, no problem...shift to second, and as soon as it hits 7,000, it does it again, just falls flat like it's misfiring. I roll off, drop the revs to about 5,000 and it runs fine. I roll back up and right at 7,000 it falls flat again. I decide to just stay low in the revs back to the office, but now it's just poorly (I can tell I'm at least 1 cylinder down) I immediately pull off so I can listen to it idle. It's idling smoothly, but sounds like a ninja 500.
I was less than a half mile from the office so I limped her on back. Parked and found that the header pipes for Cylinders 1 and 4 and cold as ice.
So at this point, I'm going to start my search at the coil. I'll raise the tank, swap the coils and see if the reverse happens (2 and 3 dead while 1 and 4 run).
Anyone else have any ideas?
BTW: About 2 weeks ago, I pulled all the plugs and replaced them. I've had the SATO pipes on for a while without a PCIII so I wanted to take a look at them. That's the last maintenance I've done.
