Cromeit left side heat fix

[Flere-Imsaho]

I started to do this mod. After quite a bit of time trying to get the aluminum piece so it would fit accurately with no gaps, I decided it was a waste of time. Instead I got a chuck of foam for a few dollars, cut it a bit oversized with a utility knife, and stuffed it in the hole. Done. It has been there for about 10,000 imiles with no problems, and it really helped with the heat.
I carried this a bit further, as there are numerous places where hot air came from on both the left and right sides. When I rode, I felt with my hand where the hot air was coming from, then stuffed the hole with foam. I am quite happy with the result.

Hi Timbo2015,

I like this idea. Did you use a special kind of foam?

I did the same thing. Go to Lowe's and look in the weatherstripping aisle. It's gray, square, and about 20" long. $3.

FWIW, I've done basically the same thing Timbo has done. I used grey air conditioning foam insulation in 2 inch and 1 inch sizes to stuff gaps through which hot air was coming. You can get this foam at Home Depot. They usually keep it with the weatherstripping. Around here the brand name is "Frost King", but YMMV.

The result, for me, is much better than stock, but I still have "tank heat", even after doing that and applying insulation to the bottom of the tank. I checked carefully after a ride a week ago when the ambient temperature was about 100 and discovered that it's not the tank, but the frame that's generating the heat I'm feeling. The frame is too hot to touch and heat from it radiates off the frame and seems like it's coming from the tank.

I'm not sure there's anything more you can do when the frame gets that hot, but it's not really a big deal to me, since once the ambient temperatures get closer to 90, the heat is not really noticeable.

Ed and Pappy and some of the rest of you guys who went the foam route - would you be willing to describe where you put the foam and did you use some kind of adhesive or just stuff it in places? Photos?

Thank you very much for sharing your experience.

I rode my 05 for almost a year before doing the Cromeit heat fix and when I finally did I kicked myself for waiting so long.

Between the Cromeit heat fix, taking out the rubber thingies on either side of the tank so the heat could escape from under the tank and a Cee Bailey +2+2 with flip windscreen I am a happy camper now.

Air flow is greatly improved now.

David, if you look up the Cromeit mod over on fjrowners, you'll find that this procedure is pretty well documented. You might also check out Bounce's (Onethumb) site for ideas on where to stuff foam around the tank. If you have access to Motorcycle Consumer News, there was an article about 6 months or so ago that basically compiled "best practices" for dealing with the heat. It was well done.

Your goal is to glue foam to the inside of the fairing at places that will force the hot air out of the "gills". Aim to seal up any gaps between the fairing and the engine through which hot air could pass onto your boot, ankle, leg, crotch, etc. I think I used 3M "77" adhesive, but again, that's documented in Cromeit's writeup. Take a piece of 2 inch foam cut about 8 inches long and stuff it in the gap between the engine and the frame where Cromeit recommends putting the metal box.

Be careful when you take off the fairing lowers. They're easily scratched.

Good luck,

Ed

Thanks Ed!

I've decided that the left-side heat is just the FJR telling me to wear my gear. I only notice it when I'm in jeans, one I put on the HT overpants, no issues.
