My 98' has been running rough after I removed the gas tank. I think I may not have hooked up the correct vacuum lines to the tank and as a result am not getting enough fuel. Does any one know how this set up is supposed to go?

Unfortunately I have the carbs... diagrams are all 99's and don't mention the set up for the carberated version.

Any one experience this problem out of the carberated version?

Yeah, its usually the hoses hooked up incorrectly.
So, basically.. "you're hosed" :D
I wish I had a pic to send you of the routing.

Unless you're running it off what's left in the float bowls, it should quit running all together.

The hose that comes off the cylinder head goes to the petcock, BUT... there are 2 places that look like it can go to. One is for atmospheric press. to get to the petcock, the other is for the hose. Check that.

I know without a pic. kinda useless.
