Its been a long time
Doesn't know nothing.
A bit more progress on the bringing back from the dead XS650D project. It seems this bike (no history) had a number of new parts fitted before it was sold. Today I found new sump strainer and side oil filters installed. All screws in place but not tightened. Oil drain plugs finger tight and obviously, no oil in the engine. All is now reassembled with new gaskets and ticked off the list.
But...... Inspection of the points and auto advance unit leaves me a question that I'd like an opinion on please.
The points and the auto advance unit itself look recent. Everything is free enough and after a light oiling where appropriate, it seems good to go. Except - there's no preload on the bob weight springs at all. The bob weights are easily moved to full advance and there's little if any wear present. But - the bob weights are not pulled back to the retarded position by the springs. It seems to me that auto advance functionality is fine. But I fear as soon as the motor starts, it will be fully advanced on ignition timing. Does that sound right? The bob weights can be easily moved with virtually no force, they just don't seem to auto retard the way I imagine it should.
Does it sound like the springs are a tiny bit too long? Thanks.
