So team Norton 650ss recommission it’s going good!
Few hiccups this week on two fronts but both sortable as I caught it just in time,
Problem one Alternator/Stator and Rotor,
So the other night I heard a loud bang 3 times as I pulled onto our road, in fast succession I quickly stopped the engine and got her stopped as fast as I could.
Did an oil change when I got back all clean and no metal,
so today I took the Alternator/Stator off and had my suspicions confirmed I think what’s happened in the inner Rotor has failed/drifted apart smashed into the alternator/stator which was the bang and knocked it off centre, fast reactions stopped it just in time as when these go they are spectacular, from what I’ve read up,
Checking the part number on the rotor it’s one of the ones that can drift apart as the magnets can come out of the body, I’m thinking that’s happened it’s knocked it in an then at the same time knocked the alternator/stator off centre, as only three were marked up, bolts were tight when I checked it out,
The alternator/stator is dated 11/66’ so both the original owner and myself got our use out of it!
I took the alternator/stator off and took her for a ride today in the heat to see if I got any noise from the mains an those all seem ok, thankfully an the run out is ok,
So the plan now is maybe to park her till after the move then get a new alternator/stator when I decide what to get, as my boot buckle on my alpinestarsadventure boots also broke gutter!
Next up was fixing the fueling and timing I did some work on re centering the cam ring on the magneto an now the timing is within a degree of each other to each cylinder, which I’ll take on a normal k2f magneto, the later 650ss didn’t get the k2fc,
I corrected Amal’s idea of ok fuel level with shims and went from fouling plugs in town to much much better running brilliant still a work in progress adjusting the in town running,
I also wanna get a new pickup for the lh cylinder,
Massive massive improvement today and a very lucky escape with the rotor /stator assy, the other day,
Great news is no damage done so when funds allow it’s an easy fix
