How Hot Do Motorcycle Exhaust Pipes Get – It’s riding season again and I was doing routine maintenance on my bike when I noticed that my exhausts were bad.

Moving from the South to the North West took its toll on my scooter. My pipes are starting to rust underneath, and the finish is starting to crack as the rust starts to spread.

Considering that a new set of pipes is around $400-$1200 depending on your model – there is only one option for me.

What Causes A Motorcycle To Smoke?

Please read this whole thing first because the last step is difficult. If you can’t…find an alternative.

High smoke paint (paint) – available at all auto shops as an engine block paint. You can also use any high temperature paint – the Helix brand pictures I bought on are made for exhaust pipes. I would recommend the brand as it dries very quickly and is good for up to 2000 deg F intermittent operation (if you ride hot, your bike may melt).

Remove the tubes from your bike – Since I don’t know what kind of bike you have, I have to let you know that. All you want are the tubes and insert covers (if equipped) – keep all the other parts for reassembly.

Use your cable grinding cup on your side grinder to grind off the old finish – it comes off easily.

After that, use the cup of the wire grinder to smooth the pipes and remove all the rust.

Now that the finish is off, you need to clean the pipes a bit to get a good finish.

You can clean the outside of the tube with brake cleaner and let it dissolve. All oil and dust should be gone after spraying.

If you want, you can spray starch and choke cleaner on the pipe to get rid of the buildup.

Place your tubes on the cardboard and spray your colored paint. Brush the nose high and try to get any build up, or you might get streaks. If there are streaks, wait for them to dry and sand them with your sandpaper and try again.

After covering both sides, take a clean cloth and wipe off any residue. It should leave you with a satin finish.

Alright, I’m not going to lose my heart. If you’re not sure about this, the instructions are from the rattle – I didn’t do it. To fully cure, your painted surfaces must be warm. If you have a pizza oven or something, you can do this if the pipes come off the bike. If not, you should do it this way.

Start the bike (with the tubes attached) and idle for 10 minutes, allowing the tubes to cool normally. WARNING:  Do this outdoors, as it creates smoke along the length of the pipes.

Restart your bike and idle for 20 minutes, allowing the tubes to cool down normally. It still smokes. Without going into too much engineering or mentioning Bernoulli’s principle, yes, exhaust pressure is a thing, and even if you don’t really care.

I’ll stick with four-stroke systems, because even though two-stroke systems have very interesting exhausts for certain reasons, most street bikes are four-strokes and that’s the concern of most of our readers. (If you’re interested, check out the two-stroke exhaust designs and the engineering behind them, because they’re interesting.)

The most important thing to know about your motorcycle’s exhaust is that it was created by a team of skilled engineers at the factory where your motorcycle was built, and not an empty pipe. There are all kinds of things going on there: the internal shape of the tube as well as the height of the header, the expansion joints and the internal passage (sometimes there are tubes in your tubes) all work together to maintain the exhaust gases. made.. work for your engine and not against it.

The exhaust gases coming out of your engine are not flowing properly. The four-stroke operation of “suction, squeeze, bang, blow” dictates that the exhaust gases blow through the tubes in the “blow” stage. That pulse can cause back pressure.

The shape of your exhaust system works very precisely with these exhaust pulses to maintain reverse flow: all the gases flow to the exit instead of going back through the exhaust port and into the engine. A well-designed vacuum will use precisely timed pulses to create a vacuum of equal duration. Not only does this remove used oil from your cylinder in preparation for the next “sucking” step but, at high RPM, it helps the next cycle of air and oil start entering the cylinder even before the piston. itself creates that vacuum. This will help engine performance, and help keep your powerband nice and wide and usable.

If you replace your exhaust system with one that is not designed for your bike (or, in some cases, not “designed” at all unless you want to count the burner and some parts of the pipes in the design) , you will experience increased noise, increased fuel consumption without burning out the back of your bike, with reduced torque, usable powerband, and overall performance. At that time all rights are forfeited. That “back pressure” believe it or not, actually pushes the gas back into the cylinder. Instead of going out the back, the back pressure exhaust gasses forward, diluting the fresh air/fuel mixture, and sending your bike’s performance down the toilet. Very flat section? A bike can run better at some RPMs and worse at others: this is usually a sign of a poorly tuned exhaust and high back pressure.

If you’ve ever experienced a leak in your exhaust system due to something like a failed header or a rusted hole, you know firsthand the absolute mess it can make. Your bike suddenly runs like crazy! That’s because all the engineering that keeps your bike moving and your exhaust gases flowing in a beautiful dance of harmony has gone out the window. No amount of tuning your carburetors or reprogramming your EFI will help; A leaky exhaust means the gases don’t come out cleanly and your bike can breathe but not out. Back pressure is what drives your bike. If you’re worried that your motorcycle’s exhaust is running too hot, then knowing the normal operating temperature can help put your mind at ease. Most modern bikes have exhaust temperature warning lights that come on when things get too hot, but it’s still good to know what’s considered “normal” so you know if there’s a problem or not. Let’s take a look at some common motorcycle exhaust temperatures below.

On average, the exhaust of an idling motorcycle runs at 600-800 degrees Fahrenheit. When you start the engine, the temperature often jumps up to 1,000 degrees Fahrenheit. However, it’s not unusual for things to get hotter than this when the throttle is opened and high speeds are reached.

If your motorcycle’s exhaust is hotter than it should be, there are a few things that could be causing the problem. In this article, we’ll discuss normal motorcycle exhaust operating temperatures and when you should be concerned. Plus, we’ll answer some other frequently asked questions about motorcycle warning signs, so read on!

Without an exhaust system, your motorcycle engine will overheat easily. The function of the exhaust is to take the hot gases from the engine and release them into the air. This process helps keep your engine cool and running at a higher temperature.

In addition, the exhaust provides a smooth ride by reducing engine noise. Motorcycle exhaust can be very hot, but sometimes overheating can be a cause for concern.

Here are some average exhaust temperatures to help you gauge if your motorcycle is running at a normal temperature.

At idle, your motorcycle is not doing much work and is moving forward. However, the average temperature of motorcycle exhaust at idle is 600-800 degrees Fahrenheit.

However, when you let the engine go, the temperature often jumps up to 1,000 degrees Fahrenheit. It is still in the normal range and nothing to worry about. When you open the throttle and get to high speed, things don’t usually get hotter.

Sometimes, the muffler of your motorcycle may turn red, and this is not a good sign. Usually, this can be caused by a bad air/fuel mixture, which is too lean. However, there are other reasons why this happens.
