Aftermarket exhaust and Track bodywork - Melty goodness.

[gyges_1]

I just installed a full M4 system this weekend on my 03 SVs with Cycleskins track skins...
The M4 collector pipe sits ever so slightly more to the right on the bike than the stock collector pipe.
This is causing my bellypan to rub against the collector pipe which didn't happen with the OEM exhaust installed.

After a few quick rides it already cooked the glass and paint a bit.
I just installed some heat wrap with hose clamps but it's still does appear to be enough. All day on track I'm pretty sure it'd melt straight through.

Any one have an ideas on how to separate them while keeping the exhaust in place and the belly pan in tact? I need to keep the setup AFM/WERA legal.

Here's a few pics to help illustrate:

if you can, use the hose clamp to further space the fairing away from the header.

my 600RR has the same problem when using track skins and the stock header. while i dont know if its legal by an set of rules... i sandwiched a ton of layers of raw fiberglass in between the lower and a plate of aluminum to act as a heatshield and riveted everything onto the lower. if i felt like spending $$ on real heatshielding, i would have put that between the skin and the plate, but ya. with no plate, my lower burned through after 1 trackday... with the plate, its survived 2 trackdays w/ no noticeable heat damage.

Id cut a hole myself.

I tried gluing an insulation pad on the belley pan last year but that did not work. Glue does not stick to fiberglass very well. :|

I ended up just laying the pad in the bottom of the pan and it protected the glass well.

Let us know what you worked out.

I think I'll try glassing around the edges of an insulation pad.
That way the glass will hold the pad in place and I'll be able to set up the proper amount of heat dissipation.

Steve...what material did you use for insulation?

I thought I showed you it at the track. I don't think I have any pics but will look.

I had a coworker wrap 1/4" insuwool with some type of grey, high temp fire blanket and stitch the edges. Lasted all season.

I like the idea of glassing in the corners. What size pad do you need? Are you going to Buttonwillow this weekend?

Awesome!

I won't be at bwillow unfortunately, I only really need maybe a few square inches. The contact point between the collector and bellypan isn't very large but just enough that if it melted through it definitely wouldn't pass tech.

Very common problem on SV's.

what I did was create a bracket on the belly pan that pushed the bodywork out a bit more. I recall, I had about 1/4" clearance.

I then RTV'd the heat insulator on the belly pan itself.

Don't use glue or any other adhesive other than RTV. It won't work.

If you are in the City I have some extra heat shield with adhesive. I use it on my fiberglass near the header.

Otherwise, just cut out that portion. It is also very easy to do.

wrap the pipe more, looks like its half wrapped in the pic. or use the adhesive shield on the fairings

Thanks Miguel, PM Sent!

cut a small hole to vent it and get that reflective heat tape and put it on the fairing

AFM/WERA Tech legal?
Belly pan needs to hold fluid and can't leak.

on my track fairings for my 600rr i cut like a kidney shaped hole more on the side of the belly pan, im sure the thing would still hold oil but dont they want you to be able to hold a quart? im sure mine does but should stop listeng to me if you think you wouldnt pass tech because i dont race.

Upon closer inspection and looking at my bike from last year...I think you may actually be on to something here. With a kidney or semi-circular cut out, I'll still retain the mount point and have enough belly pan to catch oil. And hey...further weight reduction!

cool. an get some of that Al refelctive tape and you wont have a problem at all.
