Not dead, just smell that way
I've searched but couldn't find anything in the forum just like what I'm experiencing (close, but my issue doesn't go away after turning the bike off & on.)
The Ride: 2007 FJR1300A, a couple of days over a year old with 27,240 miles on the odometer. I'm the first owner. Maintenance schedule followed. Up until this week, ran fine at all RPMs. I did have a recalled altitude sick ECU but that was replaced last December by the dealer. 25K service done by me a few weeks ago which included changing the plugs. It's been close to 2K miles since then.
Symptoms: Starts up normally. Runs fine for 10-30 minutes. Once I try to quickly accelerate at speed (for example, while passing on the highway), the engine sounds like a diesel and there is minimal to no acceleration. The RPMs remain the same (it doesn't drop nor rise). The behavior continues until I release the throttle. If I drop it down a gear and slowly apply throttle, the behavior doesn't appear. Behavior continues every time I quickly apply throttle (not a "blip") or when pulling away from a stop. Actually, while trying to pull away from a stop, I have to apply heavy throttle/clutch action to keep the bike from stalling.
Things done up to this point with no change in behavior:
- Checked the self diagnostics - No errors reported.
- Increased idle from 1100 RPM to 1300 RPM (indicated by dash tach assuming a 200 RPM delta to actual)
- Checked tank vent. I actually rode with spare key in lid and when the problem appeared, popped the lid open.
- Turn the bike off for 3-30 seconds and turn it back on.
- Checked vent hose - No foreign matter.
- Checked for kinked or pinched fuel lines.
- Checked the plugs - They were a light tan and properly gapped.
- Checked the plug wires - none were loose.
- Checked the rubber caps used for TBS - none loose and no holes detected.
- Performed another TBS @4500 RPMs
One of the things I wanted to check was the ECU Main Harness connector but I can't find it in the vicinity of the triple tree.
Any suggestions welcome and appreciated.
