I have an issue with my bike. I have a 2012 Multistrada. Bike has 24,000 miles. Bike has surging issue at 5,000-6,000 rpm and will not rev above 6,500 while riding but will hit rev limiter while in neutral. The bike will not throw and error code on the display. I have removed and cleaned fuel injectors and run Chevron Techron with new gas and it has not helped. It feels like the bike is running on one cylinder at times and has occasional misses at low revs. The bikes torque is significantly reduced compared to a healthy bike. The big is going through gas very quickly. If i unplug one cylinder as test and try to start the bike on the other cylinder by switching out the spark plug, coil, fuel injector, map sensors it runs with all configurations. Spark plugs and coils look relatively new. Both coils and spark plug give spark. Spark plugs spark is more orange than blue. Air filter is very clean. Spark plugs looks similar between cylinders, a little dark but not bad.
My exhaust servo does not move(rusted very bad) but i have tried the bike with it wired open and shut. Wired open is not too bad(just issues listed above) and wired shut robs the bike of all its power(struggles bad up hills).
Any suggestions?
