Heat dissipation experiment.

[Magdave]

I was also part of the experiment. The changes were:

1. Moved the Ambient Air Temperature and Pressure Sensor
2. Install a Fan Module
3. Install the adjustable wind deflectors
4. Install heat shields on the exhausts
5. Drill holes under the seat
6. Install new insulation on the RH rear side panel.

I measured the temps at various points on my three day ride to Florida to have the kit installed, then again on the return trip to Texas. The average air temperature on the ride back was 81, about a degree above the ride out. I compared the average temperatures and the max temperatures.
Glove box - Avg temp went up 2.4, max temp decreased 3
Gasoline - Avg temp decreased 2, max decreased 6
Tank inlet - Avg decreased 5, max decreased 19
Right Foot - Avg and max decreased 3
Left knee pad of seat - Avg decreased 1, max increased 1.

On the trip out, at each gas stop the fuel was at least agitated and in some big bubbles were present. On the return trip, at least once the gas was calm, and I don't think that the bubbling was quite as intense. Average MPG on the return trip was almost 2 MPG better.

Exactly what I suspected bupkiss. Gas is still boiling and that is the problem. The temp was low too and I suspect BRP is doing it now instead of summer to try and show improvement. Thanks for the detailed list of what was done only thing I would like to see it the actual temps to compare to what my mods have done in comparison. Can you post those please? Jet Hot header coating would have resulted in better readings I bet along with a fully insulated tank.They are still looking for the cheapest fix instead of the best.IMHO The least they could do is try the header coating and prove me right.

Didn't mean to imply a great improvement, just reporting what I saw.

I know and glad you did and you are not the first to mention minimal improvement. Only positive is a comfort improvement with the reversing fan that has nothing to do with the fire danger. Please post the actual temps please. :thumbup:

Just got an email from BRP thanking us for our participation and asking if we want the bike returned to it's original condition. Wonder how they would plug the holes under the seat.

IMHO the only part of this "kit" that should stay is the reversing fan if they moved the sensors. It is only a comfort improvement and will have no effect on the fuel dripping but an improvement non the less than having a blow torch on your legs in stop and go traffic.:thumbup:

Replacing the panels.

I would suggest to offer to leave as is for the time being so you can participate in the next phase. Once the situation is sorted out, then they can take the new production "kit" and install that while replacing items modified, such as plastic with holes cut or non standard changes like fan reversal or whatever they come up with.

You have come this far...

Also, you are in a sense valuable to the testing being a Florida machine. Honestly they should get your machine over to the test grounds on the east coast of Florida and have the engineers and techs from BRP do mods that can be evaluated on the test track and nearby towns.

The letter said that if we WANT to return to stock to let them know. The default is that our bikes will continue with their current configuration. As far as the mods go, I think the heat shields on the exhaust pipes did more than the reversing fan, but then I try to stay out of situations where the fan would kick into reverse.View attachment Can Am Heat.pdf

So has anyone else received the heat dissipation test kit? What do you think of it? The wife says the heat is still there, it's just in a different place, her right thigh. I really can't see how what they installed will make any difference but I guess they're trying.

No kit. BRP has closed the test period and no one knows the results. I was one of the tester's and it did nothing for me.

Thanks as you said it is not much better than what I get with my DEI wrapped tank. A degree or 2 better here or there. :thumbup:

Whatabout the heat melting the master cylinder and possible brake failure. I have gas fumes also. And lots of heat around the glove box and on the right passenger foot rest.The passenger foot rest is so hot for my wife with jeans and boots on that she doesn't enjoy riding on it anymore. So what about all that heat on the bottom right, possibly melting the master cylinder. That is one of my worries also.
