Hi!
I have a problem with my F6 -07 (twinspar):
Symptoms:
If I run it over approx 70 mph for 4-5 minutes it often loose rpm from approx 8000 to 5500-6000 rpm, then I need to stop at idle for a while before I can accelerate again.
If I accelerate (full throttle) from still standing the engine sometimes only reach around 5500-6000 rpm.
My feeling is that the engine is running to rich, it smokes a lot and the fuel consumption is high. No check engine codes.
What I have checked and replaced so far:
New sparks
Checked sparks = black
Injection cleaner in gas/new gas
Cleaned APV valves in advance
Changed and checked APV servomotor
Changed and checked APV wires and wire length
Checked TPS witch a TPS tester
Removed the kill switch
Removed the TSS
Looked for cable defects
Looked for air leaks
Checked cylinders with camera (looks fine)
Comp test : 8 bar in both cylinders
New primary clutch incl spring etc
Switched
New ignition coil and spark caps
Checked the fuel pressure, it varies between 42-48 PSI (service manual says 42-48 PSI)
I don't know what to do next so I would really appreciate some tips!?
