I've got a 1st gen sv w/ R6 fairings and M4 exhaust. Looks pretty, but the exhaust contacts the belly pan. I've tried wrapping the exhaust, but that only delays the damage. To get through last year I just took some RTV and glued a 4x6" homemade heat shield (aluminum cookie sheet + fiberglass + silicone pad) to the fairing... mostly worked I guess, but occasionally had to be re-glued because the RTV doesn't stick well to the fairing.

So I'm looking for a more permanent solution- either a better way to glue the heat shield I made to the fairing or a completely new solution.

Other requirements: needs to pass AFM tech and production legal (so technically wrapping the pipes there is illegal since it's not near the foot).

Thanks!
 
Yeah, tried that too. Doesn't like physically contacting the exhaust since it's designed only to protect against radiant heat. It starts burning and the adhesive fails due to the heat.
 
I doubt tech will flunk you for exhaust wrap to heat shield, you can also take a hose clamp and clamp it screw down or clamp a piece of bar aluminum to the pipe. Clamp on a piece of 3/4" aluminum L stock and it will push the belly pan down far enough to clear the pan.

Common problem with SVs. Or cut a hole in the belly pan and fiberglass a coke bottle in as a mold to get a bump.
 
Hey Ernie,

So with the fab'd spacer, you just use the stick-on radiant heat shielding stuff?
 
I had an insulating pad made for the bottom of the pan of 1/4" thick ceramic fiber. This stuff is supposed to be good for 1800 degrees. I hope it works :nerd. I will find out this weekend. I will attach a pic tonight if your interested.

Sure. Also where did you get it and how is it held in place?
 
I had it made to a size where it would not move around. Kinda wedges into the bottom of the pan. :cool

But then I used industrial spray adhesive and aluminum heat tape to secure it further.

EPOXY? :ride
 
Need air gap for any heat shield to be effective. i.e. only protects against radiant heat!

On my CBR I fashioned a bracket for the belly pan that gave a 1/4" air gap and that seemed to be enough.

Good Luck!
 
I just turn a hose clamp upside down and let the screw head push the fairing away.
 
I use exhaust header wrap on my SV where the exhaust come in contact with the bodywork with safety wire at the ends to stop it unwinding.
 
Here is what I ended up doing.

I did this because I had access to this material from work. :nerd (read cheap):laughing
 
i did a similar job to the first idea... took a 4"x6" piece of flashing (galvanized steel prob) and sandwiched about 12 layers of fiberglass between that and the fairing. however, instead of using RTV to hold it on, i drilled 4 tiny holes and riveted it there. sealed the rivets w/ some heat resistant RTV, but i have no idea if the pan would be legal for a racing organization now that its got a few holes in it. track tested it last friday and the fiberglass didnt cook at all. it got hot enough to burn me after about 5seconds of holding my finger directly on it... but its way better than melting fiberglass.
