1986 XT600 running problem
I've got a 1986 XT600 43F.I rebuilt it 4 or 5 years ago,had no problems until last week.Bike stopped at the end of the road,pushed it home & started fault finding.NO SPARK
I have a spare pattern CDI so I plugged that in & got a spark,bike runs problem sorted. So I took it for a test run & about 60mph it's hunting,then it started doing loud backfires when I closed the throttle.I then tried keeping the rev's below 3000 RPM and when I close the throttle it's still backfiring..
I've got the bike back home & now I'm wondering if the fault is
a) a dodgy CDI unit?
b) something to do with the stator?
c) something else? Anyone have any ideas?
There's no sidestand or clutch switches so I can rule out those
