Top speed reduced
- Thread starter BigDan
- Start date
BigDan, was the machined warmed up to operating temperature when you noticed the reduced top end speed? Oil viscosity due to cold temperature could reduce speed. If all was warm, I'd check the spark arrester if you still have one installed. Another thought related to temperature is tire air pressure. If pressure has reduced due to colder ambient temperature, your speed will be reduced.
50 psig raised an eyebrow. Thats 30 psig above maximum stated in the OEM Operator's Manual. That didn't reduce your speed but could reduce tire life and create a bumpy ride.
It seems as though someone else recently experienced a reduction in speed on a new 900 XT. I'll do some searching.

.... on ours, and several others. It did slow down a little.
BUT, when we serviced the machine. Boom, went right back up.
Fluid is running threw filters faster, which gives one better performance...
When a unit is brand new, there is much particles in the hydraulic that will get caught up in the filters. And of course, that what the filters is there for, to catch it.
ALL new engines and transmissions has "new shavings" on their first run.
Like stated before, need to let engine and tranny fluid heat up some before starting to run.
Your RTV will pull better with the tranny fluid hot .
Need NOT to have to much air pressure, not good. Wear to quickly, and will make tires wear unevenly. Do what tire states to run.
Quality of fuel is a source. Also, need to keep air filter VERY clean. That is why many buy or fabricate the High Rise system is to keep a clean filter so machine will breathe better and perform at it's best.
Fuel filters. Don't care if it is a so called "new filter". If you run some ruff fuel threw it. Don't care if your machine is almost new. It will slow you down and pull your power away. Just a little bit a bad fuel will not only contaminate the rest of your fuel, but restrict your filter flow.
That is why I am a firm believer in that MR. Funnel when filling up our RTV. Takes all impurities out, along with everything else that DON'T need to go threw the fuel system.

I think he meant air temperature was 50 degrees?. Check the air filter and brake have been some of the members' suggestions. I would check the transmission fluid level and might consider an early fluid and filter change. bordercollie

Hey TG. Not to change the subject, but, where can I get one of them big rat traps? Peanut? Happy New Year!!
Yes, Peanut >>>
He can build anything .....
Was worried about security on the place. Ole Tommy didn't let me down. Next thing I knew, he built and sent me the best security system on planet earth. NOTHING made it threw,
...... NOTHING
You will know the second one comes to close. Just that quick.
Sleep so much better at night now, knowing my family is safe and sound from intruders !!!!

Pepr, I do the same thing. When I am cutting wood or metal I measure 3 times to get it right. 
.
I posted a picture of how dirty my magnetic transmission plug was on the thread Pepr and Two Guns mentioned. I was glad I changed it.My top most speed was pushing 30 probably 29 mph with the xt.

bordercollieI do that too!!! Measure once, cut, then measure 2 more times so I can try to figure out how I cut it too short.
sounds like me.lmao thats one reason i like working with iron .if i mess up i can always build it up with weld or add a piece and grind it down but with wood if you cut it short your stuck with a short piece.

Big Dan, it sounds like you are having the same problems i am. I have a 2011 900xt with 40 hours on it. i have talked to the dealer and decided to go ahead with the 50hr service to see if it helps. Over the weekend I did the 50hr service with my fingers crossed and did not help the problem. My next step is to get dealer to check it out.
