Your Suzuki T500 Cobra will run fantastic with the stock carbs because I have over 2 years of R&D in this kit.
I have re-designed the entire function/fuel slope of every circuit in these 34 mm carbs to get them to do what they should have done from the beginning.

No more surging, pinging and bucking at small throttle openings !!

No more bucking at closed throttle decell !!

No more hesitation and bogging at low rpms !!

Runs cooler !!

Bike will accept full throttle from 3000 rpm in any gear !!

Smoother throughout the entire rpm range!!

Better throttle response at all throttle positions !!

See dyno charts below bike photo

Stock Jetting is very poor on these carbs....
You can see the bad bogging from very little fuel available below 4000 rpm
, then overly rich above 4500 rpm

Badly designed float bowl venting and poor needle design are the cause of this
As a result of the carbs designed this way, all other circuits are inadequate as well.

Same as above w/ torque shown
