It is a total no go in supersport. 

SB is good, but you can no longer run thunderbike.

super sport:
6.1.2 All motorcycles must meet the following requirements
applicable requirements in Section 5.
A. Original equipment wheels, brake calipers, forks,
induction system, and swing arm must be used.


Thunder bike, see F.:
6.4.2. All machines must meet the equipment standards of Section 5, as well
as the following:
A. Frame, cylinder head(s) and engine cases must be from the same
production model motorcycle. Single cylinder motorcycles may use
any frame and engine.
B. The frame must be as originally supplied by the manufacturer on the
approved model. Strengthening gussets or tubes may be added.
Only brackets or tubes not supporting suspension, engine, or drive
line components may be removed. Swing arms may be modifi ed or
replaced and rear shocks may be replaced or relocated. Single
cylinder motorcycles are excluded from this restriction.
C. Reducing engine size of machines from stock displacement to meet
Thunder class displacement limits is not allowed.
D. Fairings that meet the requirements of Section 5 may be used.
E. Liquid cooling is not allowed unless original equipment on the model
being used.
F. Original type of induction system must be retained. If a machine
originally was sold with fuel injection, then it must remain fuel
injected. If the machine originally came with carburetors, then it must
use carburetors, however they need not be the original type or size.

It can be done but like Bart posted it's against the rules.

If you run injectors from a 2nd gen on a first gen motor you need the 2nd gen intake manifolds, stator and wiring harness.

If you run carbs on the 2nd gen bike you need the intake manifolds for the 1st gen and the stator and wiring harness for the 1st gen.

I'm pretty sure thats how it works.

So you'd be good for GP and SB rules.

+1 to the other guys statements. And its not even worth it in SB, you can get more hp with the FCRs.
