So today on my lunch break I stopped off at a dealership and picked up a "Motion Pro Carb Synch. Tool." As I read down the instructions on how to use this thing properly, there was one issue that I was a little unsure about...

I've got a "Bonnie Black," which means I've got no tachometer to ensure that I'm maintaining the 1000 or so RPMs needed to use this thing.

Could someone tell me whether or not I'd be alright just finding what "sounds like" 1000RPMs, and then go to town with this thing?

Normal idle is about 1000 rpm.

Be extremely carefull not to adjust the idle too high, or blip the throttle, cause the excess vacuum could suck mercury back into the intakes.

Right, but considering I've gotten into the habit of adjusting my idle when the engine is cold so it's not dying at the first light I hit once I leave my house... I don't know where 1000 RPMs is anymore.

When I find myself doing that, after 10-20 miles on the road, I'll stop at a light and bring the idle back down now that the engine's warm.

To add a little more to that... I'll adjust the idle to what sounds reasonable, but after a few seconds sitting at a light, one of my cylinders will start misfiring every now and again... I don't really know what the heck that's about.

Why not spend another $50.00, easy for me to say, and put a tach on your bike. You can get them on E Bay for about that.

These are the instructions

That should work just fine. Set it at your normal idle as long as you aren't one of those who likes to idle with the engine just ticking over.

Set your idle when your bike is completely warmed up and then don't touch it. Use your choke to control the idle at various settings as it warms up.
