Hi folks,

New to the FJR and would like to hear if anyone has had issues with the left foot getting hot, the right foot is fine. The engine case is apparently close to the left foot and the heat goes right through the full height motorcycle leather boots. Being summer (and quite warm here now) I keep riding with my left foot at the end of the foot peg to keep some distance from the engine as possible.

Thanks in advance...

 
I am guessing you might be missing some of the foam from inside the left side fairing. It can make a big difference in terms of directing hot air.

 
Heat mgmt was one of the reasons I traded my '12 for a '16.

When the fans kicked in, the '12 felt like a blast furnace on the lower left.

Dont think I was missing any foam bits.

I lined the inside of the left leg of my riding pants with the material used to make oven mitts, up to the knee pad pocket.

Above my ankle I don't notice much discomfort due to engine heat, but the ankle bone/heal area is where I'm affected.

 
I experience the same thing as you on my Gen 3 and the source of the heat is the exhaust system. Yamaha put a heat shield on the right side and didn't bother to do it on the left.

Because of this, I've been donating material from my boot heel to the exhaust pipe every now and then and it doesn't look very nice but I've decided to just live with it.

What sort of footwear do you use while riding???

A decent set of touring type motorcycle boots will likely insulate you a bit from the heat and increase your comfort.

Ok I've put a heat shield on as recommended above. Looked at the right side OEM shield and tried to duplicate the angle on the left side. Will try it out soon. I tried to attache a photo of how I installed the shield, but couldn't find a way to do it directly.

 
I posted the heat shield because feejerbkb mentioned melting boots - unlikely to help much with engine heat on the lower legs...

My observation was in reference to the first line of this post. Not a criticism, just reporting my experience.
 
That is toasty, but some folks are better with dealing with high temperatures, while others deal better with cold temps.

 
I finally was able to take the bike out for a good spin today (ambient temps 28oC with humidity 34oC). With the additional heat shield on the left side, it didn't make any noticeable improvement when riding. The left side is still making my boot very warm to the touch at the inside heal area. (The boots are BMW Airflow.)

When I got home I took out my IR gauge and measured about 65oC +/- 2oC on both sides of the bike at the same position of each heat shield (engine running). Also measured the temperature of the brackets holding the foot pegs for any major differences, and both are within a couple of degrees.

My take is that the heat is being directed to the left side while riding. Will have to think a bit more about this, at least until the colder weather arrives in a couple of months.

 
Whatever happened to roasting nutz on the hot tank? Just cut that left foot off.

You kids are gettin' soft.

I've noticed that it only gets really warm when my boot heal is against the peg mounting plate. Moving it even a half inch out cools things down quite a bit. Perhaps mounting a 1/2" rubber pad on the plate to keep your boot away would help?
