rt 1000 issues....i could use some help!

[Wheel House Motorsports]

so on thursday i went down to idaho to pick up my new toy, and rt 1000 162 with 2500 miles on it and 1000 on the new motor. i knew things probably wouldnt be smooth right away as it is the way of the RT......

we get there and load the sled up after redoing the starter rope as the knot came undone other than that the thing fired right up and we loaded it into the trailer..... next day when i got home tried to start it and got it running, slapped it in reverse and sat and tried to go backwards, the belt was oily and slipping so i stopped the motor to clean the belt a little. started again no problem, but i stated it turned it to reverse and then it died like 2-3 seconds after being in reverse. did this a few times and then had to leave for work, so today i go out and just try to start the thing and see if it would run. i put 2/3 of a tank in the thing cuz i thought it had been out of gas. try hooking the battery charger to it and starting it and nothing but a tired shoulder, checked the relay by the battery, its fine.i think my battery may be bad, but it wont even run with it hooked up and charging. it starts for about 3-5 seconds and kinda drops RPM to about 1000 and sputters for a second and dies, and the slightest application of throttle will kill it instantly

took the sled into the garage, its way to hot outside right now. played with it a little, got the charger on it, got it going but this time it would rev up, got it to hang around 3500 with a little throttle and it was running strong. went to open the garage door and pull off the charger to get it some air, and maybe ride the field a little, but about 5 seconds after i took off the charger and wasnt touching the throttle, it began to lose a little rpm, so i hit the throttle and that proceded to kill it.

NOW the bottom left check engine light is on and the thing is back to turning on and running for a second and pooping out. i can hear the thing priming when i hit the RER button.... i need suggestions!!

Silly maybe but check plugs and plug gaps, Make sure nothing is blocking the air intake, they could have shredded a belt and got a piece stuck in the throttle body. Sounds like maybe a fuel pump issue possibly, is this an 05 or 06? On a side note I was up in Revy at the end of June and Turbo Al told me to get rid of the stock thermostat in my RT, he said put in the new xp thermostat, something to do with getting to warm and the engine retarting itsekf. I am sure you could call him to see what he meant. He said it makes all the difference in the world.

i check plugs gaps and that who thing, problem is that it ran great loading it up and now it wont run at all. and then it ran good for a second one time, now it wont run again, so im thinking it defintately could be a fuel pump

The RT didn't come with a T-stat...

 

[turboal]

fuel pump under the motor is likely the problem.it supplies the one in the tank . the one in the tank has a small chamber , holds enough for a short time of running before it empties .
you wont notice it if the tank is full , as there is a constant amount around the top fuel pump in the tank as it is located fairly high up in the fuel tank .
if the tank is only half full it is easy to spot the difference.
t state i mention to any rt 1000 owner is to have the 08 /800 t stat put into the 1000's system . this is done fairly easily and maks a huge difference to oporation of a 1000 in the mountians .big difference .

fuel pump under the motor can be changed with out engine removal .

 

[Wheel House Motorsports]

filled the tank all the way up and it took right away so its looking like the low pressure one is the culprit so time to replace it... hurray, and i will look into thermostat replacement

 

[AkHockey10]

probably nothing doing here but, How are the coil wires? and the inside of the boots?

 

[baD-MAX]

I believe the fuel pump is a recall. You can change it with out removing engine. I leaned the engine to one side and got to it.

I have not heard of the T-stat change. I also don't remember the RT having one. We had talked about installing a resistor to fool the computer, but no T-stat. At least on the '05 model.

 

[diamonddave]

The RT didn't come with one (T-stat) from the factory. In 06 BRP removed the rear cooler all together and most of us with 05's did the same trying to get more consistent coolant temps and runnability. Some have even bypassed the front cooler when they've cracked without issue. When I removed mine, I installed a reducer and this with a temp gauge (A Must on a 1000 SDI) the engine would hold 105'F in the deep fluff. Before the delete it would drop under 70'F. This isn't good while cruising down the trail at 130' and jump off in the deep. Also the Fuel-Air mixture goes way rich when coolant temp sensor drops to 70-80'F. This is one reason you see the diesel streaks on the hill when the RT's have been there. An inline T-stat would be a great investment as would a temp gauge.

Possibly if BRP had added a T-stat to the 1000 and the 07 800R, I'm sure there would've been better runnability (mostly the 1000 SDI) and less engine failures overall.

 

[Wheel House Motorsports]

gonna get a temp gauge for it as it just seems like a smart thing to do, and yes, before its warmed up the thing leaves a cloud of smoke, looks like a diesel but a little more blue, thinking about putting in an inline thermostat as it seems like a great investment that would keep the thing running much better. the RT has such a huge factory cooler down the center of the tunnel i was quite amazed, combine a well vented setup and a deletd rear cooler seems like it could make a lot of differnce for these bad boys


and i talked to the guy who sold me the sled and the consensous was the fuel was gummed up a little and need some flushing as it had been sitting for a while. so im gonna run some fuel injector cleaner thru it and see how it takes after that.

and all the recalls and updates were done to it, so it should be fine. just a normal sled sitting around for to long issue.

 

[diamonddave]

You'd be well off to replace that low fuel pressure pump and relocate it next to the battery also. Couple of options on the pump from napa. PM me if need info.

 

[turboal]

have put the 08 /800 t stat in the 1000rt . not a tough fit at all , just have to cut the hose in the correct place to install it , need a t fitting as well . that can be had from the 01/800 coolong system.or your local hardware store .
doo would have saved everyone with the rt a ton of grief if a temp guage had been installed as stock equipment on this cooling system. they tested the motor with the t stat in it and only pre production did the boys playing around in the dyno room found a bit more power with a lower coolant temp , i suspect just over 80 degrees f .
there in lies the problem of inadaquit testing on there part .on a whole the crank will go out of these motors a lot sooner than if they had released the set up with a t stat as stock equipment .
in the mtn application likely only .
great motor if you have the bugs figured out . now i want to put one of these power plants in one of my tube chassis .

x2 on the Napa fuel pump; my old man fought this for a while until he put this on. Dies at 1/2 a tank or even with more fuel when you are climbing. He lives on the east side; pm if you want his #. I am a little closer...

 

[Wheel House Motorsports]

no chit you are, maybe like 30 minutes... did you help him with this mod or not... seems like a worthwile change seeing as this one hasnt taken a crap, but it had an updated factory one put in it, so i think it might be alright.



im thinking the reason it wouldnt stay running is things were a little gummed up as it hadnt been run all summer, just sitting in the guys shop.

Yes, I talked with him as well about this and its an inline Tstat from I think the new XP. Havent done it yet tho. Its supposed to keep the crank at a constant temp as well, which may eleviate some early crank failures due to bearing outer race cooling to fast.
I am going to look deeper into this 4 sure as my motor is almost done and I'll be relocating Fpump to the batt side and some other stuff B4 the mill goes back in. FYI the RT does not come with a Tstat at all, coolant free flows and with the huge amount of heat xchangers we have & deep pow the mill doesnt keep warm.
Hopefully someone here has done the Tstat mod and can chim in with results!!!!!

 

[On a Doo]

Guess I shoulda read further down LOL ,,, TurboAl knows Doo stuff. Taken lots of my issues to him LOL.

Later gotta go to work

 

[Wheel House Motorsports]

howd ya like the RKT domes added to the mix?

Hey there all. Heres what happened to me. Took out my motor on the 1L. Mechanic swears its due to the constant going from fluff to hard packed snow conditions inconsitant temps and then it sweeks the piston. Well after a new mono jug, pistons and crank,(by the way my mechanic over greases the crank bearings do to lack of grease from factory) I got my motor back together installed a inline T-stat and took out the front exchanger. Much to my demise the 1L over heated like a banshee in the hard packed (I even had scratchers down) when this happens it goes into retared mode and no power to climb small dug out trenches.When you got into the fluff though and it cooled down the 1L ran strong. Some reasons of over heating no front xchanger, a lo cut snowflap, plus a Smittys drop brkts installed which raised the sled 2". After this day of riding I reinstalled the front cooler, installed a longer flap and milled a 08/800 T-stat into the head of the sled, and installed the fuel pump by battery, of course I had put this all back together this summer, So hopefully this will shed some lite on what to do and what not to do.

 

[On a Doo]

I think it had a bit better throttle response, prolly would spend the moola on somethin else if I did it again to be honest.
CLUTCHING is a must on this sled!
I'm gonna try the 08 Tstat on mine this year, just finished rebuilding my motor gonna shoehorn it in the sled next weekish.

 

[turboal]

would love to have this motor in a 450 lbs sled chassi . working on a tube chassi for the 800 motors and plan to buid one for the 1000 motor in the near future .this weight loss and a few other changes directed at the system and i think just normally asperated it wouyld be a fun ride .
pretty certian one can achieve a very fun track speed .if i could figure out how to down size my camera pics i could give ya a pr view .just what ya do in revy in the summer , build something off the wall .
