Alright, first few questions before you just go grab any old carb.
They are recommending a 36mm.. so.. based on some loose calculations, your going to be running between 9k-10k rpm. What is your pipe going for?
Before making a choice on the carb, figure out what rpm your peak power is going to be at.
Here are some suggestions for a 240kit
32mm carb for 8254rpm
34mm carb for 8817
36mm carb for 9334
38mm carb for 9863
39mm carb for 10121
These are based off of rpm vs displacement. Actual flow rates depend on your porting/reeds/pipe. These should be very close to what carbs you need at what RPM.
My choice of carbs go in this order; PWK(air striker), TMX, PJ, then round slides go here.
