--------------------------------------------------------------------

I have sent
exhaust, manifold, cone, head, scoop grate, inlet manifold to get ceramic coated i should get that stuff back next week.

I took the bilge bracket, tow bracket, 2 ride plates and bed plate to the powdercoater and this was the result. .

one plate is cut down the other is extended.

Yeh i know the pipe isnt to flash... will get my ski going untill i find one @ a decent price.. Is there going to be a seriously notable difference if i go a B-pipe or blaster limited, i figure there will be but to what degree.. J

[ryan]

did you happen to open the carb up and see what the jets are? i have the same set up.

What are you going to do as far as acc cable goes, have you made a bracket off the carbie to run an x2 cable? or will you be running 650 acc cable pulling from the bottom, I just bought an accelarator wheel, I have to make my bracket b4 the weekend.

[diamondaudio10]

night and day difference imo.

had the westcoast on a modded 650 motor, installed the f.p. with a mod chamber, totally different animal..

[dbrutherford]

Where did you get those cable ends at? They look like the TBM ones. But I can't being myself to pay 25 a piece for them when you need 4 for an X2 :(

[Jayski]

Yep cheers mate, Just need to get myself a hoodchop kit now....

I got them private sale from the US, i paid $10us for all of them. waste of money really, but they look flash..

Not quite finished but not far off..

ill get some time of the lathe tonight to get the prop done ;)

[heynagel]

Wow, nice pump upgrade you did there!!!! Does that take any special modification to the hull?

[phlipcyde]

trick lookin hot coat parts man... i like it..

did you lose your hood once before? ive never seen anyone strap theres down before..

[Jayski]

Wow, nice pump upgrade you did there!!!! Does that take any special modification to the hull?

Not to much, have to get a pump shoe from a doner 750sx or sxi (maybe you can get them new) then you have to muck around to get that to fit then glass or glue it in..

You have to modify your x-2 ride plate and shorten you 750sx or sxi scoop grate (or you can mod a standard 650 one i guess) but its easer to shorten a 750 one.. then you can either silicolon the whole pump in or you can build up the serounding part of the pump with glass filler and use the rubber pump seal, if you dont think you will remove it again id go with silicon.

The hood locks on x2 are shiza or on any ski really (clips have come undone yes).. If your jumping waves you would be silly not to have additional hood straps. Not to mention if you are doing stabs or subs or rolls there is allot of presure on tha hood.

[phlipcyde]

yeah i agree... i rock 4 hood hooks

[Jayski]

yeah i agree... i rock 4 hood hooks

Thats what i origionaly was going to do (even bought more hood locks) but i thought into it further, The hood has allot of flex and can often jump off the locks (when landing on it side) even with the latch locked... I figued if it can jump off with 2 then it could jump off with 4, so i thought a strap that adds support to the front as well as the back would be best....

Philipcyde works ok it seems? trick looking ski.

Thanks. It does shift a little side to side. But I'm not worried at all about it coming off. I located the front hooks down low so they pull real tight. I think your straps are pretty much the safest thing I've seen though.

The only thing that would keep my hood on was some major reinforcement on the back side to strengthen the hood, and two heavy duty straps crossing from corer to corner with stainless hardware. I eventually quite using the hood latches all together and only used the straps. Only way to go IMO.

[Jayski]

x-2guy Hood kit and new trim cable on its way... also bought a thrust innovation SJ adaptor so i can run a standard SJ airbox..... NO MORE WATER BOGGING DOWN MY SKI!!!!

Pre filters are a complete waste of money BTW, i hightly recomend never trying them..

OH and the new pump ;) what can i say!!!

[Jayski]

Do your selves a favour and get a Hood kit and a stock filter!! prob a scupper 2... Cause my ski just cost me another 1k.

[madd_dips]

ski looks siiik! i love how u used those high pressure water fittings! i have them on my rx7!

thought id post some recent pics- next thing is tubbies, carbon hood,dash and bottom filler-

[Js_440_78]

hahah the green dash suits the wheels.. u been riding much or to cold? im on holidays soon so we will have to try go for another ride soon

[madscientist]

cut the rear edges dow to the turf bro, they will not be very friendly to your body if you land on them

cut the rear edges dow to the turf bro, they will not be very friendly to your body if you land on them

which is why I cut down in the first place, to get rid of the 90deg that stabed through my wetsuit and into my knee, how far up the side have you cut?? You cannont tell in your picture....

extended ride plate with a D-cut whats the theory behind that?

[madscientist]

stock length plate (shortened shredmaster) d-cut, and tapered to fit the 2" cut on the hull. the tunnel was cut to the seat latch and the tow eye moved to the side of the tunnel. sides are cut at the top of the slope then tapered down

why would you cut your ski then put an extended ride plate on it... defeats the purpose?? Or you know not extended but stock rather than choped down?

id like to see a pic of your sides,

[Jayski]

AWSUME!!! DUDE i know she's fun to ride. i have simular set up. single 48 and 650 chamber. everything else is the same. how do you like that sxr chamber?

[Octane_114]

did you notice a big difference with the duels and sxr chamber?

[Jayski]

Unbelivable difference

Just pulled the motor out- bought MSD total loss for it and intend on doing bottom hull filler mod and reinforce engine bay and a lick of jam before the summer...

[gkeats]

If you don't mind, please tell me more about the cart gas tank. I like it.

Also, do you have any porting done to your engine? How do you have those carbs set up?

Thanks.

Carbs are twin 48 powerbombs
145 tops
115 piliots
2.5 N&S
115g spring (im going to put a 95 in it)

Yeah exhaust and inlets on the cylinder have been ported, (i didnt cut out the sleave in the inlet as many do) as has inlet and exh manifold also been ported (& no case porting, just epoxyed the drain)-

Kart tank was an off shelf item- I fitted twin pickups in the back (as can be seen) then there was 2 other take-offs which i used for return & breather, just used the factory clips which held the tank in and found some shorter straps. - hope that helped.

problem is i only get 15-20min out of the tank..

[jaxrider]

did you have to dent the side of the factory pipe to make it fit in there?

[Jayski]

na dont need to dint anything to get it in.

[Twinturbostang]

I run the chamber and I just added to the center bleed to match the water box and I moved the water fitting. I run a stock tank with no problem after alittle heating and molding.

Where did you get those cable ends by the pump?

[Twinturbostang]

Oh and in those top surf brace mounts are bent bad! Thats what happened with my jet ski haven one too. That brace is doing nothing bent like that. Also the way it doesn't bolt in at the brace let's it move, not good.

Thats why we built our Rad Dudes brace, if you just want the top braces to fix yours so it's doing something pm me. Or if you want a whole brace.

Yeah i agree its a pritty lousy design- Deffently be intrested in buying the top braces, or i supose i could just make somthing up- no reel reason to buy the whole thing if you can PM your price that would be good

yeah they fit like a glove- i didnt have to do a thing to it-
oh the the purple things- they were on US ebay about 2yrs ago, bling but waste of cash they eleminate all play in the end piece, i have them on all steering and trim, inside the hull also-

[tjindo16]

any updates on this build? i know its an old thread but it is a sickkkkk ski~!

thanx mate, ended up selling it before i put the T/L in and i believe it was parted up for an A/M hull, i bought a SJ.
