There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Excessive Heat on ST Bars

I have 2013 st-s and the heat bars usually stay at 5-6. Today it was 48 degrees when I went for a ride and within 30 minutes the heat was coming out of the seat and right side so much I needed to move around on the seat. The fan was coming on and off while riding in below 50 degrees. It was also very windy on the highway.

heat issues
My STL runs typically between 3 to 5 bars I think the highest I have ever seen it was 6 bars in 85 degree heat and yes it gets a little hot on the left hand side but not unbearable

The temp gauge measures the water temp and I do not believe that there is any connection to the temp gauge and excessive heat coming from under the plastic. My RT never went over mid range on the temp gauge and it burned to the ground

There are different kinds of heat problems. Most owners do not have engine (cooling system) overheating...staying within the normal temperature range on the gauge. Some riders experience a heat problem on the right or left foot. These are due to heat coming from either the radiator outlet vent (right) or the catalytic converter (left). They can be aggravated by high ambient temperatures or modifications that change the foot position. The right one also seems to be more evident on the Spyders with factory footboards. Another type of reported heat problem is excess heat at the gas cap, seat/tank junction, side panels near the legs, or under the seat. These seem to be relegated to the 2013 ST and RT, vary from machine to machine, and have been hard to address or find an exact cause. The most crucial problem is the chance of the radiated heat on the 2013 RT or ST melting the brake master cylinder manifold or the emissions system evap canister. These are fire hazards and the MC problem could cause brake failure. A factory safety recall has been issued for affected machines and notifications sent. If you have one of these machines be sure to have the recall work performed ASAP!
I did have the recall done. So I should be in good shape? I do love the ST, however it is like 38 degrees here in Minnesota. I may need to break out my snowmobile gear to ride my Spyder! 
Not a big deal. It's still the best riding snowmobile I have ever had and the trails are great!:clap:

That is typical. If the engine overheats you will get a warning...and probably limp mode. If your fan isn't running frequently except in triple digit temperatures or stop-n-go traffic, your Spyder is normal.

Seems to me..!!
that the heat issues have little to do with the engine temp. Most run between 3-5. The heat accumulation from exhaust cat converter combined with normal engine temp and little space to let it out is the problem. So from what you say you are fine as far as engine temp...!!:thumbup:

What would you consider frequently for the fan? I just took the Blue Recluse out for a cool 74 degree night time ride and I heard the fan come on many times (Didn't realize the fan being on so much before this particular ride, as tonight I drove without a helmet and I can hear the fan). I also wore shorts and sneakers and felt a lot of heat on my left ankle. I haven't noticed these things before. It's only less than two months old and they said they did the recall before it was handed over to me. Anything to worry about? Should I just wait to see what happens next summer when it's 112 degrees outside here?
Thanks for any feedback.

Frequently depends on the speed, the ambient temperature, and specifically the engine temperature. At 74 degrees I would not expect the fan to come on at all unless you were riding slowly or in stop-n-go traffic. At about 5+ to 6 bars or marks on the gauge it will then come on in order to do its job. The radiator discharge blows out on the right side...it should not affect your left foot unless you have cut out some panels. The left side heat is more likely from the exhaust pipe. Some radiated heat there is normal. Shorts and sneakers are not appropriate riding wear, so if you choose to wear them, expect to feel some heat, especially on the left side near the exhaust.
Thanks, Scotty. Now I could ask what you consider "slow", but I won't
. I think a few times when the fan was on I was just sitting idle in a parking lot looking at all the options on the digital display. But the other times I was probably going slow, maybe around 35 or so. I'll just start paying more attention to it. Being in Arizona with our days still around 90, I might be in shorts and just get the urge to hop on the Blue Recluse for a quick ride around town without an outfit change. So according to what you are saying, maybe the heat I'm feeling at my right ankle is just "normal" heat. Good to know. My gas cap never gets so hot where I can't touch it, but the black "bar" (lack for better words) above that going down the center of the bike under the seat does get so hot more towards the top I can't leave my hand on it for more than a few seconds. And I do get the most heat around each side of the glove box . One of these days I will start get up the guts to start "wrapping" some of the internal components on my own. I guess until Summer here, I have just been hoping in the back of my mind that BRP will come out with a "fix", bandaid, or volunteer to absorb some of the cost of providing these "aftermarket" mods we seem to be having to do to minimize the heat we are experiencing (yeah, likely chance I know). Thanks for your knowledgeable replies to this newbie, and sorry once again to the thread owner for me hijacking your thread with my questions. Next time I will start my own

Sitting still the fan will come on in just a few minutes...even at temperatures below 50. Running around at speeds below 35 can cause it to cycle periodically, especially in warm weather. These would both be considered to be normal. Heat near the right foot, especially with the fan running, would be normal (although maybe not pleasant or even tolerable). Heat on the left side may or may not be normal. There is a certain amount from the exhaust pipe, but for most riders with appropriate gear, it is seldom objectionable. So much heat on the center panel that you cannot touch it is not normal, IMO. Some 2013 ST's seems to be plagued by excessive heat build-up in this area, and the RT's to some extent too (but less noticeable due to the glove box. Some 2013s exhibit more heat at the center panel and seat than others, just as some have melted master cylinders and evap canisters and others have not.Thanks, Scotty.

The thermostat doesn't open until 3. 3-5 is pretty normal. Each instrument will read a little differently, too. There is no need to worry unless the machine overheats and shows a warning light, the fan runs frequently in cool temperatures, the fan doesn't run with the gauge at 6 or above, the Spyder suddenly starts running well well above where it normally does with no change in ambient temperatures, or doesn't heat past one bar no matter what (except maybe in Minnesota in the winter). It is because people fret and worry needlessly about the "number of marks" on an unlabeled gauge that idiot lights were invented. nojoke
