Gents,
Thanks for the info - my confusion came from the fact that its been running with a B5PES which has a slightly longer reach.
it all seems OK and I just wondered what effect the shorter(correct) plug might have (As these also fit my 240 Fantic).
My bike is one of the very last 247's 1979 and I don't know if they differed from the early ones.....
Triple X glad to know the electronic ignition is going OK ....You must let me know what Sammy Miller & Twinshock Championships you're doing as I'd like to have a go & check the difference...
Cheers
as always
