Default CB450 Tip-Over Problem

1982 CB450 Hawk.

I just joined the 0mph crash club, pavement melted out from under the kickstand and the bike slowly leaned onto its left side.

There was no external damage, I didn't witness the drop but I'm pretty sure it was very minor/slow. It wouldn't start up at first, I had to let gas evaporate for a couple hours and pull the throttle wide open to get her to start, then she leaked gas in a steady little trickle out a hose near the rear tire for a few hours. I used to not have to use the choke or throttle at all, now I have to use a little of both every time.

Now she runs just like before other than having to use choke and throttle on startup when she used to just start up without these things, gas no longer leaks, but the tachometer is reading half the revs it used to. The wire runs from the tachometer to the right side of the engine, it wasn't even touched, nothing on the right side of the bike touched the ground and the tachometer didn't touch the ground. What is going on if anyone knows?

Thanks in advance for any tips. I have the manual in the mail.

Edit: Gas is still leaking out that hose, just not as steadily.

One of the float needle valves in the carbs is probably stuck. Better pull the carbs and dismantle/inspect/clean.

Thanks for the reply! A couple other people told me the same thing.

I have an appointment on Wednesday to have it fixed. Is it safe to ride it in the meantime? The gas doesn't leak when I shut off the gas switch valve (halfway between reserve and on).

Safe to ride with gasoline leaking? Are you kidding? No way, Jose.

I've seen bikes burned (literally!) to the ground because some of that go-juice leaked out of where it's supposed to be........

Okay, tapped the carb bowl a little harder and that seemed to do the trick. There's no longer any gas leakage from the bike (I'll check it again in 15 minutes to be sure.)

I'm still worried about that tach though, how is that even possible for it to be displaying 1/2 the revs it used to? Nothing even touched the ground other than the safety bar and the left handle.
