I have problems with a nch a year again in operation Motoguzzi 850 -V7-GT. it was switched off from running operation! Now the right cylinder did not run…. and it did a barrel on… last state: from ignition candle over carburettor and control times everything renewed, ultrasonic cleaner and control times adjusted. ignition coil changed…… it always jumped and jumps immediately… but after some warming with relatively passable run, it starts to pop… and a cylinder runs t not with…. abe rs very unpredictable…. sometimes both, sometimes the right, sometimes the left alone… and then this bad bang… suspected of problems with the distributor… because the control times were obviously wrong camshafts Ot about 40° after piston OT ??? can’t be? the original Guzzi workshop book is full of errors???? distributor should run against the clock pointer, but turns clockwise? now the question is whether the distributor is properly installed. the workshop book the cams for the U-contact are different long?? how is the installation position for OT-left cylinder direction of travel, to which everything refers? it is a 1-contact distributor. Marelli what else would be to consider? I’m slowly completely at the end
