I just acquired a 2000 Jackal, in very good condition except it spits back at very low throttle settings. Pulls well and cleanly when under load or at idle. It's only at very low throttle openings that any annoying spits occur. I think the previous owner may have tried to balance the throttle bodies, and they are now slightly out of whack. I can balance the airflow between cylinders but have no access to the equipment necessary to play with the TPS. Is it possible to get this thing running better without the high-tech Guzzi test equipment? Thank you.
