brief history:
bought bike last December with less than 2.5K miles, guy did less than 50 miles in the year before I bought it
After about 1K miles trouble free, fitted de cat link pipe and Pipe Werx can, fitted servo buddy from my gen3, it worked ok so I left it fitted for a while
After about 200 miles misfire developed below about 3K rpm. Bike pulled like a train after that with no problems
Difficult to negotiate junctions and roundabouts without slipping clutch
replaced servo buddy with oem motor (cables disconnected)
refitted oem exhaust with cat, still got misfire
with such low mileage (sub 4K) I cant believe it would be the plugs, but IDK
other possibilities are 1) damaged ECU due to wrong servo buddy, (but I really doubt this one) 2) stick coils 3) Lambda/02 sensor 4)fuel pump
No F1 light or other signs, idles on 1 bar but jumps to 2, slightly rough idle
Any input appreciated...:|
