How to Remove a Grizzly 660 Yamaha Exhaust Spark Arrestor
The Yamaha Grizzly 660 comes from the factory equipped with a spark arrestor. The spark arrestor restricts the decibel output of the vehicle to 85 dB, while also suppressing any sparks or flame that may result in a fire. Unfortunately, the spark arrestor also limits the exhaust air flow and theore the horsepower of the vehicle. Removing the spark arrestor is often the first step to increasing the horsepower and improving the sound of the Grizzly 660. The job is simple and requires only one basic tool.
Instructions

Start the engine and let it idle for 45 seconds before turning it off. This will heat the pipe slightly, allowing you to unscrew the Allen bolts with ease.
2Unscrew the three bolts on the tip of the exhaust canister with an Allen wrench.
3Pull the exhaust tip out, using a pair of gloves to avoid any burns. The spark arrestor is attached to the exhaust tip and will slide out as one unit.

How to Replace the Rear Wheel Bearings on a Yamaha DT

Wheel bearings are circular parts located in the hub of a motorcycle wheel. When the bearings are working correctly they allow the wheel to spin freely. This part of the motorcycle is one which is overlooked and requires constant repair to ensure it works correctly. Finding the correct wheel bearings for the Yamaha DT is important. The information can be found in the vehicles manual. If a grinding noise comes from the wheel or the wheel wobbles when it moves, the bearings will need replacing immediately.
Instructions

Place the motorbike securely on the stand so that the rear wheel is elevated. Check to see if the wheel spins freely. Ensure that the bike cannot move at all before you begin.
2Use the wrench to remove the muffler by by loosening the drive clamps and heat shield.
3Take off the axle nut with the wrench and use the wooden mallet to tap the axle free from the wheel. Move the axle to a safe place to avoid it being damaged.
4Caully remove the brake disc from the brake caliper and slip the drive belt from its socket. Pull the rear wheel away from the frame and place it on a flat surface to work on.
5Gently tap the bearings out from around the wheel using the long drift bar. Ensure that the bearing does not become twisted around the hub. Repeat the process on the opposite side.
6Align the bearings where the old ones were. Use the old bearings to softly tap the new bearing in place. Turn the wheel over and fit the second bearing the same way
7Reattach the wheel to the Yamaha DT following the removal steps in reverse. Spin the wheel to ensure it moves freely.

How to Install Yamaha Raider Saddlebags

With its low profile and kicked-out front end, the Yamaha Raider intentionally emulates the look of high-end custom Harleys. It is an homage to new millennium bar hoppers. Yamaha calls it "chopper inspired." Choppers and bobbers usually dont have bags but Yamaha will sell you a pair anyway. Dozens of other motorcycle aftermarket companies will too. And if you take your Raider for a trip, they are likely to come in handy. This is how Hardstreet Slimbags bolt onto your Raider.
Instructions
- 1
Identify the pistol-shaped fender rail on both sides of your rear fender. Work on one side at a time. Remove the two rear bolts from one fender rail with a ratchet. Unpack the saddlebags and identify the left and right saddlebags. Attach the right saddlebag first. Unpack the mounting brackets and identify the brackets, bolts, spacers, washers and screws. You should have four of each. Read the instructions included with the brackets.
2Use two short screws and two long bolts to attach two brackets to the right saddle bag.
3Use two spacers and your original fender rail bolts to attach the right saddlebag to the right fender rail with a box wrench.
4Repeat with the left saddlebag.
