Info for my next mods ( Rn Sj )

[Sjetfactory]

I have a 96 superjet and run with
stock head,
b pipe,
vortex ocean pro air filter,
stock double 38 carbs with jetting for the pipe,
Stock head,
Stock bore 145 / 145 psi
light porting
14,5/18 solas,
R&D grate,
ocan pro plate,
-2inch pole with blowsion spring
0 degree umi hanndle bar with polished finger throttle
wamilton pump cone
800 gph bilge

Now I want somes advices on the best moves I should do for a freestyle sj.
I was thinking about oversize to 83 mm (still have a 84 mm safety overbore)
and a head for more comp.

What would you guys do? Thanks and scuse my english may suck!

Don't overbore just for the sake of bigger pistons. The few extra cc's won't make that much of a difference.
Port it and run more compression, good carbs make a big difference as well.

I only have a 701 but it does quite well for its self, X-Scream made this thing ROCK. :cheer2:

ada head to get 180psi on 93pump gas
best bang for the buck after the pipe

 

[Kennay]

definately some higher compression.

I'd freshen up the top end while you have it apart if you can spare the extra $$$

ada head with 35 CC domes for sure, bore the nozzle, flow control valve.

flow control valve ... you mean on water lines?

Fcv

flow control valve ... you mean on water lines?

the FCV keeps the waterbox empty at low speeds for increased engine response (doesnt have to clear the box of water). it mounts as seen in the picture.

Aranka, what compression you have with this head and do running single cooling is enought? tx
