The larger jets won't equal the 5 speed carb. The 5 speed carb has an oval venturi and the 4 speed has the normal round venturi.

4 speed carb will work better in some cases as i have observed. But on a stock 5 speed engine it's better to have the 5 speed carb.

For the 4 speed head to work on a 5 speed barrel get it milled and re profiled. 4 speed head on a 5 speed barrel will give very poor compression ratio and thus poor performance.

Barrel:-
Barrel also means the cylinder head. i.e. within which the piston means.
Cylinder (engine) - Wikipedia, the free encyclopedia

Skull:- Skull - Wikipedia, the free encyclopedia
Not sure how this helps in RXG topic though.

ACtually the RXG and 4sp carb is a 4TL4 00 which has a #165 main jets. And the actualy RX135 5 sp carb is 4TL4 20 with a #135 main jet. So bigger jets are not the issue . The 5sp carb has a oval bore compared to round ones fro the 4speeds.

Its a pain to get original parts for the 5sp and ofc ...many ppl have got a 5th cog mod .
