Ok I figured out the problem, I had the petcock switched to ‘off’ instead of ‘reserve’

That’ll get em every time

Well done!!  But let's be honest, that was NOT the "first" startup after 30+/- years.  No way.  Fuel was already cycled and it fired like you had been running it a short time before.   ::)

yeah but "2nd startup after 30+/- years" doesn't sound as impressive :P

I had run it for maybe 20-30 seconds before I stopped to setup and record the video

Edit: I have given the video a more appropriate title

Around the time that I started this project, I bought 4 vacuum gauges to make a carb synchronizer, so I think I’ll work on building that.

I’m going to make one sort of in the style of Dino’s from Hack a Week. His 750 build was one of my favorite pieces of recorded media ever, as a side note.

Speaking of YouTube videos, the Saturday Sessions build from Bike Exif is also very good, nice editing, funky music, and a surprisingly thorough examination of the process. The guys in the videos do a lot of things that drew criticism, but overall, a pretty good watch

That's a common fault.  Your use of the word "wiener" on the other hand...  unforgivable.  LOL

Allow the compliments to make you feel good.  Don't forget that that's the ONLY reason to be working on these old bikes.  It won't make you rich.  It won't make you cool.  Women couldn't care less.  Long hours in the shop don't do much for your health or your physique.  The only reason to do it is because it's fun.  If it isn't fun... figure out how to make it fun!

Back to bike stuff!

In the absence of stock headlight brackets, what’s a good way to seal up the top side of some stock gators?

Happy birthday belatedly wished. Congrats on getting the bike going. I think I have a good rear rim, but it is currently on the bike, a 550. Unfortunately, I cannot be as generous as Calj as I can't give it away given I bought a replacement.  Rim is pretty good, the spokes on the rim not so good...figure you just want a good rim, right?
Presuming your requests on the forum didn't net another...or you didn't hit up Bill's batcave yet.

Re: 71 CB500 Restomod - Tuning time
« Reply #146 on: May 18, 2018, 06:54:59 PM »

Got my DIY carburetor synchronizer put together, hooked it up and did a little test start. 1 and 2 were peaking at about 25 centimeters of mercury right off the bat, which was encouraging. 3 was hovering around 18 cm Hg, and 4 was down at like 6-8. I did a little tweaking on 3 and 4 and now they're all pulling very close to the same vacuum. I don't know if it's just my imagination, but it seems like it's running a little more smoothly now.

It does tend to want to die once it warms up, though, which is how this video ends.

Gettin' closer!

Edit: wrong units of measurement, whoops

Made myself some valve adjustment tools that should make the job a little easier. It was a real struggle to get the feelers into position the first time I set them, and I’m not entirely convinced that I did a 100% good job.

Gonna go through the whole tuning procedure from the manual once more and see what I end up with.

Sweet lord, carburetor jets are expensive!!

I must be looking in all the wrong places, because $70 plus shipping seems an awful lot to pay for a set of slow and main jets.

Anybody know of a reliable affordable source for jets?

Finally got my seat back today, and my wife wanted to take a picture of me putting it onto the bike to commemorate the occasion.



They didn’t do what I asked them to do, with the diamond pleating, but I’m just glad to have a seat at this point.

Also still scratching my head over these jets.  If anyone knows a good supplier, that’d be rad.
