Still no power above half throttle - Please! Iíll try anything!!
Iím dyin over here. 2011 BF750 No power above half throttle after it runs for a min - not a fuel vent issue - no FI light flashing.
Idles very smooth, starts right up - seems to have gotten a little worse, Last weekend it would take 5-10 mins to run shitty. Top speed is 28mph. Light Poppin through intake light poppin through exhaust.
Fresh top end with complete valve job
Double checked valve lash
80 psi compression
Fuel pressure 43psi (even tried another fuel pump)
Cam timing double checked (rear cam first at TR line, clockwise 270 to TF then front cam)
Ignition timing checked at idle with timing light
Tried belt reset (light wasnít on but Iím willing to try anything)
Injectors ohm 12.1 each
New air filter
Spark plugs are only a few hours old.
I killed ignition while riding WOT for about 20 seconds and plugs lightly rich, very lightly.
Crankshaft sensor checks good
Exhaust is clear.
From what i read in the manual, if the FI light isnít flashing a code, then all components attached to it are operating normally.
Any ideas??? HEELLLLLLP!!!!!!
