Hi… I have a 84 1000fe which I have owned for 9 years, in that time it has run perfectly and not missed a beat… been serviced regularly and had new plugs…air and fuel filter beginning of this year, since that service I have been out for 2 average runs of about 50 miles each… with it running as it always has
On the 3rd run of the year. I did about 15 miles and stopped for about an hour and restarted to come home… about 3 miles in. it started to lose power but kept running as I went down the gears… when I stopped it wouldn’t tick over but I could restart it and keep it going with higher revs… managed to do another couple of miles and just lost power till it stopped.
No odd engine noises or smoke but wouldn’t start again… left it for 10 mins and it restarted and managed 2 more miles running a bit rough but no power lose… got it to a friends house.
Next day it started first time and ticked over fine but once above 3 grand there was a constant backfire…wondering if anyone has any ideas?
Thinking maybe coils or spark units??
Thanks in advance
