When I try to hold the RPM at 4 or 5K the bike is Surging, bucking back and forth. It Surges when every I try to hold the RPM at any spot. It just stated to do this in the past week. It has nevr done this before.
i am having the same problem with mine.i dont know what it could be either. i changed the plugs and new injectors and new air filter but same problem. when i get paid on firday im goin to buy a new fuel pump. my friend told me this might be my problem. also what kind of exhaust do you have on yours?
i have a spare one at the house i will check when i get home from work and post it up. when i bought my new injecors off ebay the guy gave me the air box , filter, fuel rail, and left the map senser on itlo so ill check it and post back
i did replace it all. i put the other map sense on today and it help. i can feel a differenc BUT,,,,, still some surging like this guy has said and its at the lower rpm. what other senser could be causing this issue.? or is there another one.whats that senser called thats on the left side fairing. that the power commander would plug into. could this be whats causing an issue.?
