I have spark I have compression, I guess I'm tearing into the carbs tomorrow night. 
As of now it will kick but not stay running. 
The saga continues.

I'm sure my neighbours love me. But it lives ! At 10pm this evening it coughed up the last of its assembly lube and smoked to life. Video evidence to follow.

I need to set and synch the carbs. Idle is a bit off and it won't stay running when I hit the reverse button. 
Besides that it seems pretty spunky for a little air cooled twin. What little snow we have it set to melt on Monday so I figured I'd better do a lap of the yard tonight.

Oh thanks for the thread.

I'd love more snowmobile content on this site!

As a Canadian who grew up in a lake effect snow area of Ontario I spent a bit of time riding them around as friends out in the country often had a few around on their farms.  You could also hear them screaming around many KMs and KMs away in the days of two strokes and aftermarket pipes!

That noise really travels in the areas I was living in that had a lot of cleared farm land.

I would enjoy getting back to rural or small town life where I would be able to hit a trail system up just by leaving my yard.

Sadly in the city suburbs now anything would have to be loaded on a trailer and that just takes the fun out of heading over the the next town or touring over to one of the club shacks on the trail in the middle of the woods!

Thanks for stopping by and reading, I'm just trying to contribute a little piece to the mosaic that is what I found here on the best forum on the interwebs. 
 

Your comment brought to mind a little story time nugget. I grew up in a rural area with and had an obnoxiously loud 3 cylinder Polaris snowmobile. One day I was in a guys shop who built offshore powerboat motors. Think twin bbc's with blowers and the like. He mentioned my sled was pretty loud. I told him I tried to keep it off the pipe when going through towns. He replied "us people who live way out here do it for the peace and quiet."

He wasn't mean about it, didn't even suggest that my little 100hp sled has no use being loud. Just said it kind of matter of factly. Seems to have stuck with me for a few decades though. Although I still miss the sound of a screaming 2 stroke triple.

Hi neighbour! Similar story to you, I grew up just outside of Kitchener and had an old sled for a few years along with playing on them at some friends farms. I'd love to have one again just to buzz around on in a field the rare time we have enough snow.

Glad to see it running!

All the snow melted yesterday but I did manage to do a few laps of the yard first. It was ten above freezing so the machine was boggy. Some leaning out on the air bleeds got me a steady idle and reverse even worked a couple times. Quite excited for snow to return.

My father has been wanting something a little faster to run the river in front of his place. So now this is in my garage. 650cc or two stroke triple action! 

It's an early efi sled and the fuel pump is scrap. Managed to get the old pump out today and will update later.

Indy RXL? Cool! Post some more pics.

Nutters Speed Shop has lots of good content on the older Indy's but nothing specific on the RXL yet. Anything mechanical though after the throttle bodies he will have covered at some point if you run into any issues. Todd Clyne has some RXL specific stuff along with some crazy Indy mod builds.

It's a 1995 day Indy rxl touring. 
It's rough but the motor has fantastic compression and the bones of the sled are in good shape. Has the old fox shocks on it, and two up seat which is ok. 
Windshield, seat cover and some cab repairs will clean it up pretty quick. 
 

I've followed Nutters for a while but only discovered Todd's YouTube this weekend.

Step one, fire it up with some gas down the holes for motivation. Wholy moly does that noise take me back to being a kid.

Step two, why isn't the efi doing the F I bits.

Out comes the multimeter and test light. First let's make sure the injectors aren't all stuck from sitting. Apply ground one by one and they all click. Good sign. 
Next up is the fuel pump. Is the relay clicking when the key is turned? Yes, it also clicks when grounding the pink wire.

One of the reasons I told my father this was worth the gamble was because it didn't look like anyone has messed with the wiring harness. So I started at the relay. When it clicked I saw 12.6v. Good , then to the pump wiring pigtail and again found good voltage and ground. Next up make some jumpers and apply direct 12v and clamped ground to the pump....Nada . Fuel pump is pooched. Good think it's hidden behind the throttle bodies and a bulkhead. 
This picture is looking from the clutch/left hand side of the sled pointing at the dead pump.

Oh, and paint the exhaust because it makes a huge difference. So happy that the pipe was nice and solid. 
Still in the paint booth.

Oe pump on the left, late 80s ford pump on the right, close enough.

Tonight I got the new pump in, new feed line from the tank to the pump, new line and filter between the pump and the fuel rail and proper high pressure clamps. 
Everyone thinks individual throttle bodies are great. Until you need to get them back into 30 year old rubber boots.
I have a hand coming tomorrow, I did cycle the fuel pump and the system is leak free. 
I then degreased the engine, and installed the painted exhaust for an ultra budget under hood makeover.

If you need any bits, my neighbour out here in Sask is a Polaris guy and parts out sleds pretty often.

I think hes parting out a triple of some sort right now, XCR maybe.

Just let me know.

Oh man I love these old Polaris triples. We ran them in 3/4 midgets . What a sound!!! 18 of them on a 1/8 mile paved oval....Oh, and your fuel pump looks like the one in an X1/9. Very common.

Following this thread because I grew up in Quebec and everyone (except us!!) had a sled. I spent many Saturdays running around with my cousins and uncles on their machines. We had a groomed trail right beside our house and you could get on the trail and go a hundred miles if you wanted. Great fun!!

Maybe I'm old, but I like the simple Mikuni carbs on the sleds and even the old Tillotson diaphragm style. Not a lot to fail in the middle of nowhere. 

That said, on a newer sled I think FI would be nice for economy and not having to worry about jetting for temperature.

Thanks for the love guys.

Tonight my father helped me get the throttle bodies back in place. 3 pull and she fired up into a steady idle. Revs nice and tracks turning but I think the brake caliper is dragging. 
Ecu was flashing a code but I didn't have the iat sensor in so I'll get the air box back on. Clear the ECU and see what it says. 
 

Turner, I had no idea they ran these in midgets. But due to being at peak snowmobiling interest in the late 90's and early 2000s I believe the sound of the 2 stroke triple is the sound of performance. Even if my 07 4 stroke Polaris 750 with efi would eat this old two stroke for breakfast. 
 

Regardless I'm super excited that it's up and running. Time to go through the skid and clutches and get it ready for when the snow arrives.

I'm very much considering pod filters to keep in intake noise.

Man, brings me back.  I used to ice race a ZRT800 triple triple with pods back in the 2000s.  I always tell people that snowmobile acceleration on good panned snow is as fast as, if not a bit faster, than any sportbike I've ever ridden.  It's addictive.
