Depending on what you're looking for.

For sure the throttle Body will help though!!!

Is your head ported?

the cam will give you more airflow into the motor, so a bigger TB will help a LITTLE bit in that respect. You will see greater gains the more you do to it.

With my mods a +3 TB made 3+hp (770cc), on a stock bore your +5 crank will give you about 3 to 5 hp and the cam will give you a little up top. It will all work better with the +3tb

your best bet is to wait I guess. a higher flowing TB will shin better when you port the head IMO.

It seems a +3 tb is woth 3ish hp or so. This a dyno graph with Bo's track port head, 105 bore, x-2 cam, and 14 compression.

This is before and after only changes made were a +2tb.

I would imagine that it'd be less on a stock head though.

we use +3 tb's on bikes with just intake duals and pc....they add about 2 hp on a bolt on bike... the bigger the build the more the restriction so hp per $$ its a good investment....even on a stock head
