On the coils, even if they are working (hopefully!), they do look like original equipment. Can I replace with a new 12v coil off another bike model? Is there a well used replacement or upgrade?
Anyway, front brake refurb kit came and I've changed the pistons and seals a given 'em a good clean. All bled up, new pads and they lookin good. Although I'm going nowhere at the mo, I'm ready to go somewhere! Ha! Stropping is not a problem. going is! 😁
Thanks again for your help mate.
One woodruff key fitted all the 18's, 21's & 28's (and probably another zillion models) so you should be good to go with that.
Coils are easy enough to test with a multimeter, I do not want to lead you down a wrong avenue but if it is that lower cylinder it might be HT cap as it gets all the road crud and weather on it...but wait until you have the flywheel fitted on and spinning...then check the supply side to both coils for equal readings.
