Just click the link below. It's bookmarked to TPS testing page, but entire manual is there.
Im pretty sure its the fuel cutoff soloniods on the carbs - you are getting both codes so both are disconnected (probably not plugged in!)Broken solenoid leads set trouble codes 57 or 58 depending on which carb the leads are broken off. Rear is 57. The leads will break off at a lug that the solenoid windings are soldered to. If you very carefully dig out some of the rubber that seals around the lug without cutting the coil windings you might be able to solder the leads back on
the check engine light being on does not address your original problem, the engine bogging down .....Step-By-Step DIY
- You will need to insert a bolt in the hole from which the solenoids were removed - the 8mm socket head fits fine, the head fits into the recess in the carb. An 8mm x 5mm (thread pitch of 1) will be perfect & I think it looks better than the big brass plug. (courtesy of TimB007)
- You will have to "put up with" the check engine light being on
- OR - Add some electrical stuff to make the bike think the solenoids are a still there.
- Make a new harness to eliminate the fuel cut off solenoids . I made a wire harness by cutting the wires about 6'' from the solenoids. Then soldered each wire to a 39 ohm resistor (or 33 ohm OK too) and then put the other end of the resistors together and soldered a wire on , put a eyelet on the end and grounded it. I used the screw on the valve cover for the ground. (Note: Resistors from Radio Shack - in the Drawers $1 or less each). catnipp Amie (catnipp2):
