Hi guys, I have a bit of a situation. It looks like my undertail exhaust is melting through the subframe plastic base, and also happens to be right where the ECU sits. My plan is to remove the plastic base, repair the hole, and then wrap the exhaust & apply a heat shield to the tail to try and manage the heat. I was hoping to get some insight on what the best approach here would be, and if anybody has any success with a particular brand of automotive heat shielding, I would love some ideas there as well. I found these guys, which seem to have exactly what I need: http://www.heatshieldproducts.com/p...ring-heat-shields/lava-shield-for-motorcycles Any thoughts? I really appreciate the help, I do not want to risk catching fire or frying my ecu while on track :bounce:
I have a heat problem on one of my bikes. In addition to the wrap which is a great idea you could protect the plastic with some aluminum adhesive tape. You can find it at Home Depot.
I left the stock black plastic that has heat tape on it and haven't had an issue. If you don't have that piece just heat tape what you have.
It could be a lot worse. My MV Agusta likes to melt it's own bodywork. Needless to say I keep on top of that like a crazy person.
Yup, keeping an eye on this will now be a part of my routine after every session! :nod: But you are right, could be much worse.. (Same exact situation, bike, pipe, having gone unnoticed until it was too late)
So that photo. I still am fascinated. Did it do that after it was parked I hope? Or did you end up like this guy?
Got a question for the OP....Since you have an after market exhaust on the bike, did you also add a fuel management computer...I.e. Power commander, Bazzaz, etc? The reason I'm asking is because if you didn't, the bike is going to be running lean. Lean = hotter! Depending on how lean, it could be somewhat hotter or all the way to OMG hot!
Thankfully neither happened to me :amen: That was a picture I found from someone on the zx6r forums. Just glad I caught it early. No, I haven't added fuel management mods. I really would like to but for now that money is going into track time. My main focus was ergonomics, brakes, and well, you have to have a nice pipe right? :rawk: So far it doesn't seem to be a problem, but I will keep an eye on it. It shouldn't be running lean to the point of motor danger right?
Thank goodness for that. MMM MMM toasty might be good for a Quizno's sub but not for near your backside. Glad that was not your bike.
A slip on exhaust, if the cat is still in place will not usually run as lean as if you put on a full system and the cat goes away...which equals a lot less restriction in the exhaust flow. I would say that there is not necessarily a high percentage chance of engine damage because of a lean condition, but my point is that running lean could very well be causing enough heat to do the damage that you are showing. I'm certainly not an expert in this area, and I would seek out other opinions from folks that are truly more knowledgeable than I am....it just seems to make some sense to me......leaner = hotter everything.....engine, exhaust header, oil, coolant, muffler, etc.
I definitely like the logic of it, I will have to make sure I keep an eye on a few of these things. This temperature gun I picked up is turning out to be a pretty good investment. Tires, coolant & oil hoses, exhaust :getdown:
