A passing fuel **** would not in itself cause carb flooding. The level of fuel in the carb float bowl is controlled by the float needle valve in each carb. If the needle valve was passing then your carb would flood, but you would notice that because eventually your bike would be sat in a puddle of fuel.
Are you using 89 octane fuel or was that a typo and should have been 98?
I have used 91 octane in mine and it splutters and farts like a granny on boxing day!
Run the tank low (or better still MT), drain the float bowls and fill with 98 octane unleaded and note what effect this has. let us know how it goes.

 

98, where would someone even get 98? Most gas stations here on the east coast don't go above 93 or maybe 94. And IIRC most of the country is about the same if not lower.

89 is fine for these bikes, I've tried everything from 85 to 93 and 89 works best for me.

 

Big upgrade from a Nighthawk to a Superhawk isn't it? I had a '92 750 prior to the '02 Superhawk...

A worn needle and seat in one of the carbs or even some dirt stuck in there preventing a good seal could cause this.

 

hey everyone thanks for the replies.

I may have forgot to mention something...
it only does it if the bike is completely warmed up, 200+ degrees, after it sits for a few minutes while off.
...after thought: I wonder if maybe its not getting fuel right away and I am the reason it floods.

for more clarification, i live on a farm in Nebraska (yes, we have electricity and tv )
the only fuels offered around here are 87 regular and 89 super (e10) then if i drive 20 miles i can get 89 regular or 91 super
or i can get a drum of 110 octane race fuel, that i use to run in my drag car....

that being said, I have never had any problems running e10 unleaded(super), Ive run it in every mower, 4-wheeler, 3-wheeler, jet-ski, boat, motorcycle, car, pickup, suv, i have ever owned.

this bike only had 6200 miles on it when i bought it back in april

yes sir, i had a '00 750, loved it but wanted more power and less weight, the superhawk is a perfect combo of both, plus the v-twin sounds amazing p.s. couldnt resist the awesome smilies...

 

I vote 'dirty seat for the float needle, in one of the carb units.'

 

it hovers around 1200-1300 rpm at idle



...im gonna run another can of seafoam through it and see if it clears it up.

 

if it's running fine until it heats up I don't think even 10 cans of seafoam would clear it up.
