Thanks for all the input. I inspected the cap it looks okay except the rubber seal seems to be crack from age. I took it for about a 20 mile shake down, hate that term cause it shook some things loose, almost lost my speedo damn bracket shook loose and the clutch freed up and had trouble shifting. Another thing this is a project bike that has sat for years so things are loosing up, it may have also been beefed up before I got it. Compression is about 130 per cylinder and it just feels more gusty than bikes I have ridden before.
Any way, it ran real good as long as I stayed in 3 gear and did not go over 45mph. Just got back and anytime I hit it and cruised in 4th, I can go about 1/2 to 3/4 a mile and it starves out. I will get a new fuel cap tomorrow not sure about the petcock might just try a high flow to see if that is a problem.

Dan89,
I checked the diaphram and it looks solid no pin holes, tears or cracks. It seems sealed just fine. I did manage to put the put the needle jet in wrong but I fixed that problem. Lastly I just looked, and the one thing my carb is missing is an acceleration pump it not there, s am I running wrong carb on my bike?

I know you say that the bike is starving for fuel, but it may be an ignition issue...

Since you disassembled the carb, make sure that the needle jet wasn't lost in the process. It can easily fall out and go unnoticed. It can also be installed backwards. The big end of the jet should face up, into the carb throat.
You can see the jet by looking into the carb throat. The slide needle goes through the jet.

Is your needle installed or shimmed correctly? I think those year needles are richer in the midrange to compensate for no accelerator pump. Any later carb will fit also your bike, search Ebay and look for the carbs years 1991-2003 at least.
