Got a few other things done though. Gave the bike a tune up and managed to goof that as well - must focus.
Tune-up's are pretty easy it seems and I think (at least standing still - we'll see once it's got a load on it) the throttle seems more responsive. Little quicker than it was untuned to get up and down.
The points
Two screws and out they come - mine took an impact driver to get em loose. Looking at the heads it seems the PO didn't have one as they're pretty nicely rounded
Off comes the points plate
and then the mechanical advance - from anything I can find this isn't worn too badly?
And then I thought I'd try and make sure the shaft was straight as the timing light showed some flutter in the window at idle and I've read this shaft being slightly bent is the reason and makes it a little jumpy at idle
Mostly failure. I think I'd like to blame the tool here. This one is from Harbor Freight and has a pair of vice grips and stand that has a wire running through it that you tighten up to make it stable. Pretty sure that getup sucks as I couldn't get it to stay stable to save my life. Of course blaming your tools is like saying you're a crap musician because your instrument's cheap.
At any rate I tapped it a couple times as it did have a slight wobble but never got a decent baseline. So I left it at about half a mm or so (I think - my gauge is in inches - see the rim truing debacle for more)
Cleaned up the points, lubed the cam with some moly I've got left over from engine assembly, slapped it all back together, gapped the points, timed up 1-4 and 2-3 (the manual mentions the use of a dwell meter. I don't have a dwell meter so maybe next time) and then found I had some red sparks coming out of the 2-3 points.
http://forums.sohc4.net/index.php?topic=49167.msg519696#msg519696Turns out that was another attention to detail issue as I'd put the condenser connection back on with washers on both sides of it. The actual order is washer - washer - condenser - insulator
Then I got a chance to use the Morgan Carbtune. This thing is AWESOME compared to the Motion Pro. Don't even think about buying a Motion Pro sync. Seriously. Here's what happened the first time I hooked up the Motion Pro. Suckage.
Also, get the brass fittings for the Carbtune if you do. The nylon ones are way difficult to get onto 2 and 3 so I scavenged the fittings from the Motion Pro. Hooked it up and get this
Maybe that explains the number 1 sparkplugs black deposits compared to the rest when I did a chop awhile back?
Fiddle with the adjusters and get this
Much better - more responsive. Easy too. The advice I culled was to pick the one farthest out and adjust in pairs. So I did. Seemed to work pretty well. There's still some flutter in the gauge at idle (tweaked shaft on the points cam showing it's effect?) but maybe that's normal.
Also attempted to replace the tach seal. Turns out I got sold the wrong seal - just a hair too tall which I figured out after seating it and not being able to get the screw in without chewing it up. Replaced with the original and it doesn't seem to leak so...
and finally laid down a second coat of epoxy appliance paint on the side covers after wetsanding the first coat. They seem to have come out pretty reasonably.
If you're wondering what the roughness is on the left one - the PO had attached the badges with some kind of rubberized sealant. Scrapped it off as best I could but didn't get it all up.
Next week I'll buff them a bit and refit the badges with trim tape. Hope that will hold them in place.
