The "having to give it throttle when warm starting her" was the biggest reason I did my buddies...that's bull crap that a fuel injected sled needed half to full throttle to start it when warm.

One pic of her ripped all the way down...
Don't be scared, it looks a lot worse than it is. Literally not that many tools required...flat head screwdriver, phillips screw driver, spring puller, wire snip, 10mm socket, 8mm wrench, 2.5mm allen, some wire to hook her to a 12v power source, and a quality multimeter. I might be forgetting a tool or two, but it's really not that bad following Eric's directions above!

I think they could have taken a little more time and got yours closer to the correct specs...it's a bit touchy to get things tight and still end up with correct readings. Let us know how yours runs now though!

So whats the point of having to take the fuel tank and air box off? Is it to gain access to the idle screw? Im doing a 2013 pro now and I just lifted the clutch cover and oil tank to get access to the sensor and the idle screw is right on the other side behind the silencer.
Me too!! And i will post how she runs once the storms pass and i get to shred some of this awesome powder that has fallen over the last few days!! =)
Still curious if the "spread" of the numbers (.240) is the most important, or the numbers themselves (.700 base, and .940 idle). Any comment on that from anyone who has the same spread but with different base and idle numbers?

Location of idle adjustment has been moved from the previous friendly spot...

Damn engineers must have had some time on their hands because they placed it in the most non-friendly place there is!

My sled only reads 4.97 volts going to the tps, would this be a problem for the poor idle? My sled is a 2012 but I do have the new vforce reeds and from what I have read is the tps set up is the same. Does anyone know what would cause it to be only sending 4.97 volt?
Only a couple of options, poor connection with your test leads, or the meter your using is accurate enough. Eric

I was using a mac tools multimeter so I thought that would be fairly accurate. I set the tps based on that 4.97 volts to start with, do you think I will have running issues with that? I haven't had a chance to try it out yet
Guessing both of your settings will be .03-.04 volts too high.
Even if its off that amount you should still be close enough to not cause a problem. Ride it and see.
If you end up redoing the adjustment, when you check your supply voltage and dont see 5.00-5.01 with your meter just stop at that point.
I have seen issues with 2 different MAC meters over the years. Both of them had random issues of not being accurate and caused lots of issues trying to diag problems. I own lots of mac tools, but NONE of their meters. Eric

FYI...ran my sled yesterday after adjusting TPS per Eric's directions above and she idles perfectly!! Also think it helped the rich bottom end perhaps...
I have 4.21 volts on my meter. Innovative 3320. Reads 12.13volts off battery
Innovative 3320, Isnt that like a 20 dollar meter from wal-mart, amazon, ebay? I dont think I would proceed with that meter. Eric
Most people on here wont have a Fluke 27 to use or borrow is the issue....
One of the qualifications of this thread, for the layperson, is that you will need to have professional quality tools to do the job.
One of the best threads of the season, IMO, however!!

Changed the batteries in the Innova and game me 5.00 on the yellow. my initial idle was .941. what the crap, why do I not idle and boggy. checked baseline and it was like .743. so now I have adjusted to speck, going to borrow another meter tomorrow to make sure it is good. First time and no idea what or where to adjust, but thanks to the good descriptions, figured it out. Hope she idles better!! And you really do need like a 12" or longer extension. it is a pain.
Just got done doing mine, took me exactly 3.5 hrs. I borrowed a Fluke 175, and used the battery out of my 06 Silverado which had 12.24 volts of charge. For starters, the TPS had a supply voltage of 5.00 exactly. Measured the idle spec and read exactly .940, backed off the idle adjustment screw (3 turns was not enough, I had to go 3.5 until the screw was backed off of the cam) and and the base setting read exactly .716. With the idle spec reading dead nuts but the base setting being off, this lead me to believe why I think my sled idled good at home (at 1500 ft) but would not idle well on the mountain, 1300-1400 rpm @ anywhere from 8500-10500 ft and also cut out at times. I proceeded to adjust my TPS and dialed the base setting to exactly .700 and then readjusted the idle screw to dial that back in to .940 exactly. Reassembled everything, sled idles great at 1700-1800 rpm @ 1500 ft, I leave for Togwotee next Thursday, I hope it runs much better out there this time! Don't remember reading it but may have missed it, I highly suggest to remove the exhaust silencer to gain room to access the TPS. I replaced that suitcase with a nice new shiny HPS can while I was at it 
Thanks a BUNCH for the info SRXSRULE!

Just wanted to report back. I wasn't idling before, would keep dying and super bogey on the bottom end. after TPS settings fixed, ran like a champ. idled great, no bog and super fun!!! Thanks SRX
No snow here so wanted to check mine now rather than when I should be riding
From the factory the idle was .942 and base was .714
Adjusted to .700 and .940 on the nose. Very easy to do.
Extra bit of effort to remove airbox makes access a breeze.
Thanks again Eric!
