2013 RT Heat Issue - Solved?

I am a newbie to the Spyder world. I traded in my 1200 cc Moto Guzzi Norge and bought a new 2013 RT Limited one month ago (November 2013). On my first extended ride (200 miles), the seat became uncomfortably hot. Searched this forum and found some were experiencing this problem with a '13 and some were not. Took my Spyder in for its 600 mile service with the intention of also having my exhaust pipes wrapped with heat tape, as others had suggested on this forum. The Service Manager suggested he may have a fix other than wrapping the pipes. He said his solution had worked on two previous 2013 RT Sypders. He was rather elusive on discussing "the fix", only saying that he had been able to reduce the heat under the seat by 50ºF on two previous Sypders. When I asked if he would perform "the fix" on mine, he said Can Am should be paying him to fix it. I agreed they should pay, but suggested it was my family jewels at stake, not Can Am's. I asked if he would be willing to give his fix a try on my Spyder if I paid for it. He agreed to do so reluctantly. I got the impression he did not hold Can Am in the highest esteem for not addressing this issue and/or ignoring his suggested solution. I didn't want to get into the politics, I just wanted to get my problem addressed.

When I went to pick up the Spyder, I spoke to the mechanic that actually performed the service and asked what was done to address the heat issue. He said there are two fuel lines that go to the throttle body. The lines are rubber and just slip on to a barbed connection on the throttle body. There is nothing securing the hoses (i.e. a hose clamp) only the friction of the hose on the barb. He went on to explain that these engines run hot to begin with and when they get hot, the rubber hose expands, allowing more air to be sucked into the system. This makes the engine run more lean. More lean means it will run hotter. There fix was to replace the rubber hoses (didn't ask, but assume they replaced them with more heat tolerant hose) and zip-tie the hose onto the barbed connection on the throttle body.

It was 35ºF when I went to pick up my Spyder from service yesterday, so I cannot report if "the fix" addressed the issue. It was also misting rain and I beat a path straight home. I can only say that their explanation certainly makes sense. I was charged 2 hours of service time for "the fix", which was around $180. If it turns out it does reduce the heat by 50ºF, I will be a happy camper. It is a shame to spend +$30K and have to search for your own solutions, but sometimes you have to play the cards you are dealt.
Hope this helps others out there that are experiencing the same issue.

P.S.: I also had the dealer install the BajaRon stabilizer bar. As others have stated, it made a good deal of difference cornering (more flat, considerably less body roll). I have not had a chance to get out on the highway to see the difference, but the added cornering stability gives me confidence that the stability on the highway will also improve.
 
Welcome..!! Welcome..!!

this has come up before and hope you get a chance to ryde again soon to see if in fact it does work reducing the heat. Keep us posted..!! welcome to the roadster world and as you have found, the best place for answers to your questions. Hope they get this heat issue resolved soon so you can really enjoy the ryde..!! :ohyea:
 
I'll keep an open mind and wait for your summer report.




Edit. Think you are referring to the two vacum hoses, not fuel lines.

As to "the fix"... An air leak would certainly lean out the mix; rubber lines couldn't (or shouldn't) expand enough to be the cuplrit.
I hope that it works for you! :thumbup: Please let us know what happens next!
 
First I've heard of this one . . . but it seems to me that, as the rubber heated, it would become more pliable and the suction would just make it seal better, rather than leak . . . but stranger things have happened! Looking forward to how your Spyder operates in summer weather . . . sure would be great if the fix was that simple! :yes: Welcome to the :f_spider: world!

The bike could not be running so lean that hose clamps on the fuel lines would net a 50ºF drop. No way. You should have insisted the pipes be wrapped even though it would cost you dearly.

When you look at the design and layout of the pipes relative to the gas tank etc, it is clear where the heat problem is coming from. When Honda had the Pacific Coast (PC800, 1989-1996) out as a body wrapped motorcycle, they did a very good design job to address problems the BRP folks should copy. This motorcycle used a V twin 800cc engine. The most important design feature to contain the heat was the use of double walled exhaust pipes from the heads to the pipes below the body. The double walled pipes contain the heat and noise very well. If BRP had double walled pipes, we would not have to wrap our pipes and heat would not be such an issue. The other design feature is the use of a housing around the heads where some of the airflow from the radiator is ducted into the front of the box and exits out the back and down. This helps a bit in the heat, but more importantly helps isolate the noise. The PC800 is a very quiet bike. Is wasn't build for power or speed; just a quiet and capable commuter bike.

Wrapping the pipes, and providing more insulation around the fuel tank, brake master cylinder cap, and evaporative canister would be my best bet also...
CuznJohn has also added a lot of extra ventilation to his RT in order to move any trapeed hot air out and on it's way. Take a look at his modification too! :thumbup:
 
i just found out

hi bob i also found out that i need to also cut or drill holes in the plastic behind the radiator fan to let the air go into the engine compartment. that allows the lower vents i put on to send cool air to the engine. i was wondering if i had to cut it out so i called jean at virtika and he said OH YEA I FORGOT TO TELL YOU THAT lol
 
Doesn't make sense to me either.
If it was getting that lean to make a 50F increase you would think the spyder would be throwing codes too!

my 2013 gas cap has been too hot to touch....plugs were chalky white....now after wrapped pipes, gas tank etc......temps still get to 150F at gas cap...but just off cap to tank 170F.....I would bet there is a 50F difference from before wrap to now....I'm not a mechanic.....just saying

I Agree wrap pipes and add insulation to gas tank. The only way to go.
There's 100+ deg. diff between wrapped and unwrapped pipes.
 
:welcome: and :congrats: on your new ryde. :2thumbs:

Will keep watching. Would like to hear a hot day driving experience though. :thumbup:

Off topic post -- you're a fellow PC800 owner! Great bikes, treasured by their owners, under-appreciated by everyone else. Run forever, carry everything, ride and handle great. I apologize -- now we can get back to the subject at hand.

Yes. Rubber expands when heated.

Rubber has a coefficient of linear expansion of 77 x 10-6 m/mK. In comparison to other substances, this value is quite large.

I regret that I did not "shoot" the temperature under the seat prior to taking it in for service. I have a laser infrared temperature gun that I bought to "shoot" the tires on my motorhome, but it did not cross my mind to use it in this instance.
I will report back after riding on a hot day, but unfortunately, my feedback will be subjective.

The shop will wrap the pipes for $200 and this is still an option (they are giving me a break on labor because I just bought the Spyder from them). The "fix" they tried did not negate wrapping. I still posses the exhaust wrap, stainless steel lock ties and Hi-Temp silicone coating. The Service Manager agreed wrapping the exhaust would drop the temperature. He said he wraps the pipes on his race bikes, for somewhat different reasons (so he can work on them right after a race, higher EGT encourages faster exhaust evacuation, more hp, etc.). He did favor his approach first, saying: "Let's try this first, it has worked on two other Spyders".
I agreed to do it because it sounded promising, it was simple and while wrapping has its advantages, I have read feedback on this forum that there are also disadvantages (i.e. moisture entrapment, embrittlement and finally failure of the pipe).
The Service Manager did ask that I leave the wrap in case his "fix" didn't work. I have no clue as to how he measured the success of his "fix". All I know is the wrap, ties and silicone were in my rear trunk when I went to pick up the Spyder.

I see no downside to trying this fix, only upside. If it doesn't work, then we all know it's a rabbit trail, I am the only one that has wasted any money and wrapping is still an option. If it works, we all win.
I have found a great deal of VERY useful information on this forum during my very short time as a Spyder owner. I am just trying to be helpful to those experiencing the same problem.

To the gentlemen that suggested the rubber lines replaced were two vacuum hoses, not fuel lines....you are correct Sir!
 
Thanks for the info. Looking forward to hearing more about it after you get to test it when it's warmer outside.
