vacuum hoses

I hhave fixed a problem that caused me to pull the bike apart and pull the motor. The one thing i am unsure of now is how all the vacuum hoses go back on. Does anybody know where I can get diagrams on where everything goes?

There are two vacuum hoses that go to your carbs: one small one comes off the lower brass lead of the petcock and attaches to your front/left carb - there's a brass nipple on the carb that is your connection point. The rear carb also has a brass nipple on it (to the right, rear of the carb) and that hose runs from the carb to the emissions valve that sits behind the gas tank.

For the reed valves: One of the larger hoses (probably about 5/16ths) comes off the left reed valve and I believe hooks onto the emissions valve...I think it's at the lower center port. The other large hose hooks onto your right reed valve (it's the hose with the 90-degree bend in it), comes under the airbox, and hooks into the upper center port on the emissions valve. And finally, there's a hose that comes from the airbox and hooks onto the emissions valve at the remaining (left side) port. Keep in mind that there should be a rubber grommet between the airbox and the hose coming out of there.
