Idle should be 1200 per the service manual.

I would double check the timing on your cam.

 

2nd that on the cam timing

 

That is usually a sign of leanness. Either the pilots are clogged or improperly adjusted. Also a faulty TPS can cause this.

 

I would also check the petcock diaphragm.

 

Alright I checked the TPS and it was good. I'm don't think it's the jets since it was running fine before the head swap but I'm really leaning more towards timing since as I've been riding it I've noticed that at higher speeds (~6k rpm in 3rd and 4th gear) it has no power so I'll be checking the timing tomorrow.

 

If the timing was off it'd most likely start real hard and not run very well anywhere, not just at higher RPM's.

The guy who previously owned my bike said it ran fine on the forums then after a CCT failure and after replacing a head said it started popping and sputtering over 7K. After I bought the bike and went through the carbs the jetting was all off. Once I got the jetting sorted out now it runs great and dynoed at 9hp more than any other Superhawk I've dynoed.

What is your jetting? What pilots, needles, and mains are you running? Also make sure you didn't have some dirt or debris get into the carbs while you had them off.

 

As your are getting a lot of advice pointing in different directions, so lets break your problem down.

This is what you have given us:
As you have changed a head we do have to take the possibility of the timing being 180 into consideration.

I really don't believe this is your issue but to check this you would need to set the other cylinder to the proper TDC (as set forth in the valve adjustment sequence) then rotate the crank the proper amount of degrees to the other cylinder and see if the cams are pointing the proper direction.

We can walk you through this or just look at the manual on how to adjust the valves.

No the most likely issue would be fuel related.

Which would leave you with one of two problems. You are either going way rich or going way lean due to running out of fuel.

If it is a rich condition (which could be assumed due to things getting worse when you pull the choke out, which is actually an enrichment circuit) then for some reason your mains are all of a sudden way too big...possible but not very likely.

Which leaves going lean or running out of fuel. This can also be the reason it runs worse when you pull the choke out. The reason for this is that the fuel in the bowls is already too low and opening the circuit lowers the level even more.

This is why I have said the first place you should start is the petcock. You have already checked the vacuum line which leaves two more things to check and eliminate before going any farther.

First is the petcock all the way open? Second would be is the diaphragm damaged.

By your symptoms of running out of power and erratic idle (which could be a sign of a vacuum leak) I would disassemble the petcock and check for tears or a pin hole in the diaphragm.

Sure you can start anywhere you wish but until you are sure you have adequate fuel flow, then you are just chasing your tail IMHO

 

Thank you for the guidance and I'll check the petcock first and go from there.

Timing off by 1 tooth, pilot jet clogged, carb sync way off, now much better but still has flat spot at 7k rpm.

-- Detailed Version --
Well first off I haven't checked the petcock since it wasn't hooked up backwards when I took it off and it worked fine before but I did take the carbs off and cleaned them out and found the pilot jet for the front carb was partially clogged. I also checked the timing and found that I did have the intake cam off by one tooth and that got it running somewhat better but now I synced the carbs and it's running much better except for a small flat spot at around 7k rpm but it's only momentary. I am going to sync it tomorrow again since it wasn't fully warmed up when I did it tonight but it was way off.

 

UPDATE!! It's running beautifully! It was cam timing all along, somehow the rear was off by a tooth and the front was off by 2 teeth. All sorted now and pulling like a banshee again!

 

Haha, great! Dang motor wants to be synced up like a soroity house to function well; wonder why Honda doesn't fix that .
