problem starting after gas tank removal
I removed the gas tank to have it painted. I reinstalled everything as it was before the tank was removed. The bike started initially and bogged down after about 30 seconds. Now it's turning over but just not starting. It sounds like the petcock is off but the valve is open. I do not have a vacuum hose from the back of the petcock but I didn't before I removed the tank either. I have a suspicion the vacuum hose is to blame but I'm not certain since I've never had one and have never had this issue. Any thoughts?

one more thing to double-check. the petcock on/off indication labels are ***-backwards in my opinion. to me, the petcock is open when the labeling implies that it is in the closed position and vise-versa.
i actually stopped closing it when i remove the tank, due to the hurt it would later put on my brain. if i leave it open and note that, then i don't have to worry about the Honda petcock riddle labels. and gas won't spill out when it is left open if the petcock is in good working order, since the system requires vacuum in order to pull gas.

Great
Omg, I will be pulling my hair out in the near future. My project hawk is a "from scratch" build up. It's little stuff like this that has me worried. I'm tearing down two bikes to make one extremely nice one. I will be pissed if I'm without a bike this summer.

Which is opposite of the CCT on the front cyl.

Do as Greg (Hawkrider) suggests on his website for carb sync set-up. Cut the vacuum line under the left rear of the tank, between the tank and the frame in front of the seat, then put a 5/32" vacuum "T" fitting in the line and cap the 3rd opening of the T with a vacuum cap. You now have an easy disconnect and, after removing the vacuum cap, a vacuum connection to the front intake manifold for carb sync.

Or do like I did... Take the freakin petcock and cut the lower nipple off, it can still vent, and now the emount of nipples and hoses match each other... That works fine for me...
