The fastest way to ruin your new powersport drive belt is to simply install it. If you don’t break the belt in properly, you’ll find yourself shredding the belt instead of the terrain. In fact, most powersport belt failures can be attributed to improper break-in and clutch adjustment – or not breaking in the belt at all.

Ensure the best performance and longest life from your G-Force belt. Follow these three steps when installing a new belt.

1. Install the Right Belt. Using a belt that’s even slightly different than the OE specs can affect performance – or stop yFou in your tracks.

2. Align and Clean. Align the clutches according to manufacturer’s specifications and clean the sheaves with a Scotch-Brite® pad. Remove old belt residue, glazing, oils and debris with alcohol or acetone on the clutch sheave area. DO NOT USE BRAKE CLEANER.

3. Install and Break It In. Perform two heat cycles in 20 miles. Conservatively run through the entire shift range, without exceeding ¾ throttle. Bring the belt back to normal operating temperature (15 minutes) then shut down and completely cool the belt for 30 minutes. Repeat the process.

    DIY!!
    Bought this cabin air filter for my 2015 Honda CR-V and it fit perfectly. Installation was super easy and only took a few minutes. I immediately noticed the air coming through the vents smelled cleaner. No need to have it replaced for you. Definitely worth it if you want an affordable replacement that gets the job done.

    2015 Civic
    Size fits properly on a 2015 Honda Civic SI sedan. Price could be a little cheaper for a non-OEM part.
