Checked the pushrods...they're fine. Would one cam lobe deteriorate that badly...on one side only? Must admit,this one is baffling me! ???
Thing is, if a cam lobe is worn it would reduce valve lift wouldn't it? Considering that there is back pressure through the inlet port to the carb on part of the sequence...would indicate that the valve is opening longer or at the wrong time? ???
One coil with a distributor or 2 coils with two sets of points?I'm thinking either the wrong cylinder is using the other cylinders points putting one spark 90 degrees out of wack.Sent from my shoe phone!
'92 model , doubt if it has points KR . Dusty
I think you're right, Carl's drawing shows an electronic module of some sort with two coils, perhaps it's fritzed but it could be still crossed over. the thing to do is see if ther's a good spark on the non running side.Roy
So.... what kind of ignition is it running?
I'm putting my money on (let me know where to send it) Dusty and his ignition timing question. Shouldn't you be able to pull both plugs, crank it slowly by hand and witness a spark somewhere near TDC on each cylinder?
Says Moto Guzzi on the electronic ignition pick up plate. Swapped all ignition wiring and tried all combinations..good spark both sides. Looks like I'll have to remove the cam next to have a look. The right side tries to run but just backfires. Exhaust is clear, good spark,[/quoteThie backfiring was what made me think perhaps the ignition was crossed over, it would fire ok on one cylinder but be 90 degrees late or early on the other. it's not the sort of misstake you would normally make but may be the reason the PO gave up on it, I'm sure it's quite easy to get it mixed that's why you need to check both cylinders.On the Indian I built up of parts with no point of reference I timed the front cylinder points correctly for the rear cylinder plug, of course the front cylinder was way off because of the uneven firing pattern. It was just a matter of swapping the wires and re-timing.
