This afternoon Paul came down from Auckland with a spare PGM-II, a spare set of carbs, a spare wiring loom and a few other bits.
We were about to swap the carbs over when we realised that first we really needed to get the PGM connectors properly sorted.
So we put the bike in the van and headed around to Wob's, as he had an old F3 loom that we could salvage the correct connector plugs from. After a little while, the connectors were fixed, but the bike would not start.
The spare PGM-II was installed and all of a sudden the bike would start reliably with a kick start. Cool.
The bike was now running, but still wasn't quite right. It sounded as though it was too rich and was burbling and not free revving.
We swapped out the carbs and the bike ran beautifully. Even though two tubes to the air valves were not connected.
We connected up the two air valve tubes and plugged in the original PGM-II. The bike ran about 95% sweet. However, it was just noticeable that it wasn't revving as cleanly as it had on Paul's PGM-II. The fact that it ran this well at all was a bit of a surprise, as it was previously not running well at all on the original PGM-II, but now with Paul's carbs on it seemed to be running only slightly rough on the original PGM-II.
We re-connected Paul's PGM-II and the bike ran beautifully again. So clearly my original PGM-II has a slight fault but not bad enough to prevent the bike from running about 95% sweet. Odd?
So at the end of the day, there were 3 main things wrong with my bike when first assembled:
1) Sheared Woodruff key on the flywheel
2) Slightly faulty PGM-II
3) Something not quite right with the carbs. This is yet to be determined. (ended up being missing needle shrouds)
But also the seemingly good battery was just not up to the task and the kill switch had been previously modified so that the connections were backwards. Who would have thunk it. A bit of a torturous combination of problems to overcome, and that's putting it mildly.
But at least I now have the bike running properly. Excellent.
Note that someone had previously tried my original PGM-II on his bike and had reported back that it worked fine. This lead me to believe that there was nothing wrong worth my PGM-II. However, I am sure that if that someone tried it again, with the knowledge that it isn't quite right, he would notice the difference.
