i checked the coil for resistance with a multimeter (ohms tests) and all seems good except for some minor adjustments to the coil lead to plug then i got a reading again. thought this might have been the problem and still could be. i checked the measurements with the other coil and it was very similar.
i looked at most of the connectors and all seems good. I cleaned a couple of greenish connectors too and now am going to check all connectors (well most)
i checked the pulse generators, but apart from a little greasy all seemed okay, there was a difference in gauge, i.e. 0.40 thou rear cylinder clearance and 0.50 thou front clearance. i degreased the lot and took it for a spin.
I didn't dare ride as fare this time as i didn't want to ride it on one cylinder all the way home again. this time it went off the front but came back on for much longer and seemed to idle better. i get the feeling i've probably got a poor earth somewhere as it feels like a minor electrical short which i think is in the wiring loom under the tank as it all seems a little untidy and when i got the bike and had a look around it etc i might have dislodged an old coupling or something.
so i'll do the resistance checks on the wires linked and connected to the front ignition and pulse generators and then go out for a run to see if i've cured it.
AT LEAST I'M SPENDING SOME QUALITY TIME WITH HER THIS YEAR BEFORE THRASHING IT NEXT YEAR.
I'VE ALSO GOT VERY GOOD AT GETTING THE BODYWORK AND TANK OFF.
P.S having wanted fuel line couplings for a while but being to tight to pay £20.00, i've found a mx dealer who sells them for £7.99 for 6mm and 8mm pipe if anyone is interested. i've ordered two myself and will let you know what they are like.
