Having owned a 2003 GTX DI for 6 months, I've had to do a lot of research and trouble shooting to remedy problems. If any of you have questions pertaining to your DI, please don't hesitate to ask.

Hello, thanks for the offer. I'm looking at a 2003 gtx that doesn't run for under $2k--thoughts on whether its a good deal or not. I don't think its a major issue, rather something else (fuel or electronic related). Is it a good machine and if so, how fast should it run on a good day.
DI.....direct orbital injection
Do a search in the forum with our search engine using the word "DI". If this machine is not running, it could be a host of several issues. This system injects on the high pressure side of the engine and needs a compressor to build enough pressure to overcome the compression stroke to do it. The fuel is injected in a two stage system. The fuel rail has a valve that opens to add fuel to the injector, then the air comes in behind it and pressures it up for injection. There are fuel regulators, pumps, solenoids and many other sub components that make this thing work. The compressor also drives the RAVE system........
You might want to look these components up in our "parts" link above. Put in the year and ski, then, when the page opens, select the fuel system. You'll see how much this system has to make it work and you can also get a feel for the prices of the parts by clicking on one, then adding it to your cart.
Good luck!........make sure you make an educated decision on this machine.
Oh, BTW, I've been told by other DI owners that have never really had problems with theirs, this machine screams.........!:cheers:

Kind of an old thread but I'll respond in case you (or some other doo-head) are still considering.
I own (2) 2-stroke DI's with excellent results. The 03 has a little bigger hull than the '00, better handling also than that and previous GTX's. I have rebuilt both top to bottom end, they (DI) are the envy of the 2 strokes and here is why...
Start ups, instant! no choke to mess with, seems like less smoke also, less emissions.
Fuel Economy (vs. my many friends with identical carb models) you will go 1-1/2 times the distance easily. On my 03 GTX I can go the distance of my lake (37 miles) and back on 1 tank and still have enough to hit a cocktail off the beaten trail. The carb models "Definitely" cannot come close to this.
So go DI, dowse the old fashioned gas hungry carbs

Thats o.k., bring up an old thread if you think there is some good you can contribute.
If you've read the forum's threads on the DI's, you'll take notice that I've said, if you have one in good running condition, it can't be beat for throttle response.
Unfortunately, most members who come in with the DI, have had nothing but a lot of trouble with them. They are very intricate and hard to trouble shoot because of the amount of components that control it. It's not like real fuel injection, it's more like a 2 part fuel system. Compressed air to over come the pressure of the cylinders.
The other downfall is the compressor system is what also drives the RAVE's. If this air line gets a hole in it or malfunctions, not only will it disrupt the performance of the engine from a lack of sufficient RAVE functions but loss of air from the compressor to the fuel rail will cause the engine to run bad too.
But your right, there isn't any 2 stroke on the market that can out perform the DI model, when it runs right.:cheers:

Wow. To read about the DI models, makes me think about a woman. When all is going good, nothing can touch it. When they are not good, well, nothing can touch it!
He he he!

I guess I'm use to them, I think they are VERY easy compared to my new supercharged 4tec ski. My friend and I buy ski's that people orphan at dealers when the dealer tells them.. it will be 2500 to rebuild your engine. We buy them, fix them... some even come in with seized pumps that dealers "guessed" it was engine failure (not even bothering to bypass the pump). What a joke those are.
We just finished a DI (that a dealer told the owner it was terminal
... only did top end and an exchange on the counter balancer (previous user let the balancer synlube run dry as it ate the gear). Crank and bearings were excellent so the ski purchased for $500 had a total of $300 added to it including some new decals from babbits, add to it some (highly recommended) 3M Scratch remover, then a coat of McGuires wax and bamm... got a DI that runs (and looks) like new, now worth more than 5 times the investment! Oh time spent? probably 3-4 hrs (blew a night after work) and would have been faster if the jug bolt orings were not so (as usual on older models) stubborn.
DI's are more complex but not that bad once you know the language, don't be afraid, once you understand them you won't go back to carbies.
Oh by the way.. anybody want to rid their DI... CME!
