Yes, because of the rubber O ring. Which I don't have because mine have disintegrated. I will have to find something to put in there.

Yes, we can agree on this.

Thanks for posting. Maybe I didn't research enough. I expected there to be a noticeable lip so I thought those threads were probably...

If I understand correctly you think it will come apart as a product of putting it together? Or you think it won't withstand the stress...

Gary, Thanks for doing this. I guess I'm incurably old-school as I never think of using my phone for stuff like this. Great idea though...

Thanks Gary. I know how to do that but these pieces are so small I can't see how they mesh, esp. with my big fingers blocking the view.

I didn't see a lip to pry so I found another way. I don't much care what you think of my skill level. Help if you want to, or not.

Yeah, but it won't go in any further than 2 turns. If I try to force it I'll just end up stripping the head.

I could try that. Wonder if local hardware stores would have the tap since they didn't have any screws that small.

Wingman, I do have one of those but the screw from the tach does not match any of the sizes on it. I have measured the diameter as...

te to the 5mm stated by gggGary. I don't have any way to measure the thread pitch. Even if I did I probably wouldn't be able to see it.

That would be much appreciated. There are still things I can try. There is a metric supply shop in North Denver but that's an hour drive...

Ordered this. Waited a week until it arrived today. Looks like size is correct. Went in 2 turns and then wouldn't go any farther so I...

Thanks Gary! Maybe I'll try this when I do the speedo. It's pretty easy though to cut it. Took about 5 minutes.

Skull, Thanks for posting, only mine does not have a raised lip so there's nothing to pry on. I did try briefly but couldn't get...

Gary, Thanks for your response. OK, you're saying I should have created a new thread. I'll take that advice for future posts. Wasn't...

Thanks Jan! I took a screw out of my laptop. It was the same size but the thread was different. Haven't been able to get to a computer...

Disappointing no one offered a source for the tach screws. Guess I can tap in a larger screw but rather not do that if I don't have to.

My tachometer has 1 screw missing. My hardware store doesn't have anything that small. Looks like maybe 2mm. 3mm was too big. Anyone...

OK I have disassembled the tach using the technique recommended by RustyPyles, with a thin grinding wheel around the circumference of...

Yep!

Gary, I had so many problems with the petcock that I took it off and replaced it with a regular gravity one. I don't think that can...

OK, I'm an idiot. Looks like maybe it was a loose spark plug wire. Shouldn't be loose but... Next question: is there any way to get...

I've been working (slowly) on getting my 1980 650SG running again after many years of neglect. Finally got it started but it doesn't...
