Why Not Drill a Few Holes in the Fairing?

[SacramentoMike]

Figured that topic line would attract some notice. Had the bottom fairing off today and I got wondering--Why is there that big solid piece of plastic below the radiator, directly in front of the four pipes coming out of the manifold? (Talking about that triangular center section.) With the heat problems of the FJR, it seems a few holes in that plastic would give better air flow and carry that built up heat away. It doesn't look like anything behind that area would be too affected if some mud or something got past the plastic wall. So has anybody tried this, or just have thoughts on it?

Pile on !!!! They're gonna get you on this one. Hahahahahha.

Oh these silly noobs, many have gone before you. Check out fjr1300.info for all you may ever want to know.

 

[Old Michael]

Good idea. DO it. Drill 'em. Don't mess with the airbox though.

 

[twistedcricket]

There might be a solid reason for the lack of perforations there. It might need to scoop up the air and divert it towards the radiator, which would help to explain the results from the fjr1300.info site (didn't cool).

"Trust the Force, Luke" - the bike will be just fine as it is. I've ridden in triple digit heat and the bike has done well to keep itself cool.

Wow, what a concept..take it further however, and drill holes in all of the fairing pieces. Bet that let alot of cooling air get to the rider.

Better yet, they should make fairings out of screen...that be even better..

No Wait! Just remove the entire fairing all together!...that would certainly keep the rider in all that "cooling air"....

Michael, its been done and reported as not successful, for the reasons stated above. DO click on the link and bookmark the site by HMarc. His is one of the original knowledge-based site for the FJR and is a library of information.

The problem with trying to force more air into the engine compartment is that it has no comparable exhaust vent area, so the heat will be forced out the side vents and cook your legs, or just be "air locked" and nothing much will be accomplished.

Sacto Mike... You OK...???

And the air that goes those other places is air that's expected by the radiator. Sure the air is cooler if it's not heated by 220-degree water first! But if the radiator has no cooling airflow, bad things can happen.

But in the first post, he's looking for a way to carry off "built-up heat." The problem is there really isn't any built-up heat, it's just airflow not as well managed as it could be. GenII has a redesigned fairing to address this, but those of us with '05 and prior have to deal with it.

One of the best things I did on my '03 was a heat blanket under the tank, keeps the tank from absorbing so much engine heat and cooking your legs. Look for something like that.

Blanket under tank works well for me. You can also search for the "cromeit heat fix". Haven't done it yet... maybe this year.

Simple fix: Run a PVC pipe with a scoop from the rear of the radiator and below the tank, terminating below the fairings in the air stream. Cut the bottom at a 280 angle (not 27, not 29, not 30, but exactly 280!) facing the rear of the bike. Now, as you ride, the air stream will create a low pressure area (Bernoulli Effect) at the opening and it will draw (suck) down the hot air and dispel it below the bike. The faster you ride, the more hot air that will get sucked out! Really!

Don't drill any holes into anything! It'll effect your re-sale if you do! Just put 1/2" of blocking under the forward 2 gas tank bolts and lift your tank 1/2". This will do wonders for Airflo! No heat problems here! Suck water on a hot day through a straw = lots of it! Also don't forget to urinate!

'05 FJR 1300 a (37,000 + miles)..It takes a lickin,' and keeps from tickin'.

Heading to Chico soon, I think it'll be a full moon? :glare:

This has worked for me since I got the bike in 2002. It doesn't run hot and cools off the exhaust.

How about this one?

Jim, what is the pad forward of the pegs? Highway rest?

 

[Grumpy]

They're called Highway Ottoman's and were adapted from what they use on BMW.

I seem to remember that a number of people who have opened up this section found that the bike actually ran a bit warmer.

Would it possible to run the exhaust thru a heat exchanger and then back to the front of the bike and

have it piped thru with a power vent system and redirected thru the lower quadrant?
