my servo motor went out when i turned the run switch to on the motor would keep winding and never stopthere was a 35 error code soi swaped out the servo with a used one that i know was working when it came off the bike. now the servo works for about 30 seconds and rotates the pulley when i rev the bike after starting but the 35 error code a fi light comes on again and the servo stops working the bike does have a flapper mod i used a screw to fasten the flapper to the air box could this be the reason for the problems
