The bolt I'm pointing at is the one that will get the helicoil.

All others hold pretty tightly.

you should be able to use the case as a drill guide i dont think the drill bit will be too big
the kit should come with good instructions
any light oil works well for tapping aluminum
if it is a gun point tap you wont need to do any back and forth motion with tapping, just run it in and halfway to desired depth back it out bolw out the chips and finish
put the coil in at least half a coil below surface and don't forget to break off the drive tang

Thanks for the tips! I've tapped steel before so I assume it's a little easier with aluminum. And I was thinking the same thing about the case being the guide. I'll go slow.

I can't quite figure out how to break off the tang without seeing the kit yet, but I'm guessing a magnet is involved.

you reach in with a small std screwdriver and just bend it back and forth a cuple times
bending motion inline with the threads so as not to pull it out of groove once it breaks
should be able to blo it out

Quick question...when I took the engine apart, the guy left out the gasket under the oil pump. I looked in my gasket kit and found a gasket for this area, but it is literally a piece of cardboard. It's not gasket material, literally pressed corrugate. Is this gasket necessary, and do I actually use this crappy gasket?

While this was a while back... That gasket IS just paper you can cut your own oil pump gasket from a Manila folder if need be, but that doesn't make it pointless. Gaskets seal and space components correctly.

I agree about that. I figured the spacing thing out the hard way with camshaft end play, binding and a sheared kickstart shaft

I do have a little play in the clutch basket. Maybe 1-2 mm as it slides along the transmission shaft until it hits the circlip holding it on so maybe the spacing isn't an issue because there's some slop there?

I'll try to find the video I posted a while back.

Not sure about that one. I wonder if the play will be taken up by the rod and adjuster once the left hand cover is back on. You could put the rod ect and left hand cover on sans gasket and check?

That's OK.

Wow, this is a thing of beauty. Ricks cb175 rebuilt stator. New wires too. Matt, this will make it easier on us to solve the wiring instead of those three "white/brown" wires!!

Left side buttoned back up. The only complaint I have with the new stator is that whatever epoxy they used to coat the thing dripped all down in the threaded holes in the stator. I learned that the hard way when I had the stator cover gasket installed and had everything bolted down, then tried to get the rotor cover on and the bolts didn't want to thread in. Took it all apart and chased them and now we are good.

I was going to install the other side cover too but discovered that the gasket I bought was all kinds of wacky. I could probably make it work, but I'm afraid I would wrinkle it if I forced the holes to line up.

Little bit of carb cleaning tonight. Don't have an ultrasonic so I'm hoping a ton of carb cleaner spray will work ok. So far so good.

Boil 'em in lemon juice.

I was about to do that until I saw some nasty pics of some carbs that were chalk white - granted probably over baked in the pot - I think the guy said he did it for like an hour.

I think I have an old pot laying around...
