KART SUPPLY 30 Series 788 Drive Belt — Trailmaster Mid Xrx-R & Blazer 200-R, Direct-Fit for Bearing-Driver Clutch

KART SUPPLY 30 Series 788 drive belt for Trailmaster Mid Xrx-R and Blazer 200-R is a direct-fit replacement belt designed for newer models with bearing-driven clutches.

When your Trailmaster Mid Xrx-R or Blazer 200-R starts slipping, squealing, or losing acceleration, the most likely culprit is a worn drive belt. This 30 Series 788 belt fits the later-generation go karts that use a bearing driver clutch instead of the older bushing-style setup. Before ordering, check your old belt for the stamped number 788 to confirm compatibility; if that number is present, this belt is the proper match.

How will this 30 Series 788 belt affect my kart's performance?

Replacing a stretched or glazed belt restores smooth power transfer and consistent acceleration. A fresh belt improves grip on the clutch and reduces slipping under load, helping the engine deliver power efficiently to the rear axle.

• Restores designed RPM and acceleration characteristics.
• Reduces clutch chatter and belt squeal under throttle.
• Improves traction between clutch sheaves for repeatable starts.

How do I confirm this belt fits my Trailmaster or Blazer model?

Compatibility centers on the belt size and the clutch type. Look for the stamped number 788 on your original belt and verify your kart uses a bearing-driven driver clutch as found on newer Trailmaster Mid Xrx-R and Blazer 200-R models.

• Check the old belt for the number "788" printed or molded into it.
• Confirm your kart has a bearing driver clutch rather than a bushing clutch.
• Refer to your owner manual or parts diagram for 30 Series belt specifications.

What are the signs that my drive belt needs replacement?

Worn belts exhibit visible damage and performance symptoms that are easy to spot. Replace the belt if you see cracking, glazing, uneven wear, or if the kart slips and lacks the usual throttle response.

• Cracks, fraying, or separation in the belt material.
• Glazed, shiny surfaces indicating heat damage and reduced grip.
• Noticeable slipping, delayed acceleration, or inconsistent top speed.

How should I install and maintain the replacement belt?

Installation is straightforward for anyone comfortable with basic go-kart maintenance, though a service manual or a simple online guide helps. Keep the belt clean from oil and debris, check alignment, and inspect periodically to extend life.

• Follow torque and alignment specs in your kart manual during install.
• Avoid contaminating the belt with engine oil, brake fluid, or solvents.
• Inspect after initial break-in rides and at regular maintenance intervals.
