Dear Guzzi Fans I’ve had a V7 850 GT year 1972, which basically runs reliably. Currently I have the following problem, which I can’t explain easily and is slightly different from the thread V35 on the topic of jerking (see below) The MG jumps well and runs round. Acceleration is also full throttle in gears 1 to 4 in all speed ranges no problem. Only in the 5th gear it does not take full throttle and comes into the jerking. With half throttle it accelerates normally. Problem of course, this motorcycle is not about full-gas driving, but I want to get to the track of the problem before further complications occur. At first I thought about the ignition, but contacts are right, too. I will now still have ignition cables (they have already made problems), spark plugs and plugs exchange. Presumably, however, that it comes from the fuel supply, so at maximum consumption (greater gear, full acceleration) too much ode r too little petrol arrives. Maybe also a filter dense or similar. Does anyone have a tip or idea? Thank you and Gruss, Hans
