How to Drill Out Motorcycle Exhausts
The process of drilling out the motorcycle exhausts is to make the motorcycle louder. Many times, the loudness of a motorcycle can alert other drivers that they are near, and while many come with this loud feature already, some motorcycles have been quieted. Here are a few easy steps to help you pump up the volume and keep yourself riding safely.
Step 1 - Check Out the Manual
Using the manual (or if you have lost the manual you can typically look on line to get this information), locate the exhaust pipe and the bolts that are holding it in place. Put on a pair of gloves to make sure your hands stay clean and out of harm's way. Using the wrench set, take out the bolts as well as the exhaust pipes.
Step 2 - Wrap and Hold
Take the first pipe and wrap it up in the rag. Use the vise to hold it in place and make sure that it isn't so tight that it is damaging.
Step 3 - Drill
Attach the drill bit to the drill and then drill into the end of the exhaust pipe until it stops. This is called the baffle, and you will want to keep drilling through the baffle to make sure that you get out all of the metal pieces so that it won't whistle.
Step 4 - Repeat
Now that you have done the first one, repeat steps two and three on the other exhaust pipes. Make sure to clear out each one thoroughly.You want to make sure that you won't have a whistling sound when you are riding. Getting this done right the first time will keep you from having to take the bike apart again after testing it and drilling more. If the hole is even and cleared out as you drill, you will not have any problems later on.
Step 5 - Reattach
Now that each is drilled out, you can take the bolts and reattach each of the drilled exhaust pipes back onto the motorcycle.Make sure that you look at each bolt after you have put it back in and test that it is tight enough. Using the wrench, you can secure it and then use the pliers to push it a little extra to make sure that it is as tight as can be.
Step 6 - Test It Out
Now that everything is hooked up, you can put your bike into neutral and then start it up to listen to the noise.
One tip to keep in mind is to make sure that you only drill through one baffle in each exhaust pipe. The reason for this is that the motorcycle may end up not having enough power, and you will have to have more work done to fix that problem.
