New Moto Guzzi Door Mats Available Now
My first impression from your symptoms is that the ignition is firing on the exhaust stroke.
but it only runs on the Left.
Classic Dyna failure..
Good to know that what I described is a common Dyna failure, thanks Chuck. Now to figure out how the points system goes back together, somewhere there has to be a picture of what goes where and the wire connections, I seem to recall it’s pretty simple but I’m pretty simple as well😳If anyone has a good photo of their dual point Guzzi distributor with the cap off you might save this old fart a lot of grief! Thanks in advance.

Original points and condensers back in, bike fired right up!My timing light is on the Fritz, so it’s off to the auto parts store to buy a new one, timing by feel and ear’ is basically ok but I need to set it at full advance. It appears the Dyna just would not trigger the right hand cylinder at the correct time, there was a spark with the plugs pulled and grounded but it just would not run on the Dyna on the right cylinder, strange. Something to be said for good old points.
30k miles since I set the points on my Convert, still the same gap, timing hasn't moved at all. A little dab of Bosch Distributor Grease is key to this.
That IS impressive. Anything with points I have had, have required adjustments somewhere between 3 and 6k miles and replacement at 12,000 at the very latest, unless fitted with electronic "condenser".
Condensers are key to long life for the point sets. Cratering is going to tell you if your condenser is not quite right. Transfer of material to positive side you need a condenser with higher capacity or shorten condenser lead. Transfer to the negative side you need a lower capacity condenser or lengthen condenser lead. Sounds like Charlie has it right.
