The rebuild has begun
Not much happened during the past few weeks but now things are back on track.
I have received the last few parts from the polishing shop – the carb bodies and I got new floats and gaskets waiting to be installed. Tonight i rebuild the carbs!
In the mean time I started on the right side engine cover. I swapped the points. It’s a weird set up where the 3 points are not all the same. I also installed a new oil seal in engine cover for the kickstart. The seal was different from the stock unit as the outer part is made of metal, it looks more like a ball bearing. Twas a bitch to put it in, I had to heat the cover in the oven at 90C for a bit while I placed the seal in the freezer. The heat expansion allowed the seal to fit but it took some hammering.
I also re wrapped the wires that go to the points in heat shrink tubing as the original plastic tube was all brittle and cracked.
Bonanza
Once again, ebay delivers. I have received a whack load of parts in the past few days. I am still missing a few items but the pile is getting high. Most impressive was the new piston set. They came from Japan in under a week!
Most other parts are either from the UK (points, oil seal) or the US.
Some parts have been tricky to get. I sourced the SRIS oil breather hoses in california along with one of the alternator brush (the positive) but I am still looking for the other (negative) alternator brush.

Points
So the points are badly pitted and the little bakelite rubbing blocks are all worn out. I have the Kokusan points rather than the more common Nippon Denso and these parts are getting rare. I found a set of replica on ebay from the UK. A bigger concern is the breaker cam. Obviously the cam has been running dry for a while as it is all rusty and. I’ll try to smooth it out with fine emery cloth if not I’ll need to find an NOS replacement.
