Aussie Combat came around yesterday and we adjusted the valves. They were all a bit loose, we were able to fit the next thou gauge in each.
Afterwards we fired her up and still had popping out the exaust, this time mostly out the r/h pipe. AC went back to the shed to grab tools to adjust the Boyer plate and I adjusted the idle and let her sit at 1000rpm while we waited. Idled fine. AC adjusted the plate about a "poofteenth" and then I revved it.... no problems.
We went out for a quick 15 minute ride and I opened her up a couple times, still no problems.
Was it the valves? Just had torun a few minutes to clear out all the carbon built up from weeks of short, low rpm running during diagnostics?
Was it the miniscule adjustment in the Boyer plate? I remember them needing a bit more movement to make much difference.
Could it just be that I had cleaned out the not very dirty carb last week?
Ah well, I'll take her for another spin today and see what happens.
Still not sure if the original charging issue is solved, perhaps that was just an anomaly that will not be seen again. Before our quick ride the batter was only sitting at about 10.5v, after the ride is was back up to around 11.4v.
All in all, I'm still a bit nervous but we'll just have to wait and see. And it was bloody good to spend some time in the shed with a fellow Nortonite, haven't done that in years!
