Thanks. I don't have points. For years the bus has run v.well with regular 2000mile adventures across France, spain. I want first to fix this current issue which I'm sure is to do with leads, plugs or a short somewhere. Later perhaps I'll change to regular points. I mean I don't want to try too much in one go. Perhaps the acuspark is the problem....I could try putting a normal king lead in.
A comparison...the hole on the new leads looks slightly smaller in diameter than on the old. When fitted on the plug the new lead requires more effort to pull it off. Sent from my SM-N9005 using Tapatalk
In the end , when you have changed all the traditional ignition components, it could very well be a failing electronic module. I believe they have enough electronics in them to go crazy - one of mine killed the ignition at about 3000 rpm, but as the revs dropped it cut in again. Sounded like a kid in an Opel Corsa with a rev limiter... Vroom vroom bang bang vroom vroom..
Yeah!! Fixed that juddering...it was a loose king lead and a slightly too large a gap on one valve. In the end an easy fix. A great run in the sun. Sent from my SM-N9005 using Tapatalk
Its worth checking that the insulator at the top of the coil has not charred while sparks tracked across it. What happens then is it reduces the effective width of the insulation so you may start seeing the judder return on damper days. On one of mine it took a fair amount of sanding to clear the damage - easier because the coil used a brown insulator, so the blackened part was easy to see..
just got back from 600 mile run to wales and back...lumpy, juddering struggling on hills... seems it was a stretched accelerator cable, plus an air filter that looked like a fur ball..no fuel no air tightened cable so it got some fuel..always a good idea, and vacuumed air filter...get some o2 too. running like a good un straight after. unbelievable difference. just my tuppence. total job...3-5 mins.
