TB Manual Clutch Kit – All 6V CT70, 69-87 Z50, SL70, XL70, CL70

Upgrade your 3-speed semi-auto engine to a full manual clutch with this high-performance conversion kit. Designed for 88cc–108cc bore and race head setups, this kit includes a durable 3-plate clutch and 67/18 primary gears—making first gear more usable and providing smooth, consistent engagement without slippage.

Features:

• Full Manual Conversion: Converts 3-speed semi-auto to manual for better throttle control and rider feel.
• 3-Plate Clutch Pack: Handles the added power of big bore kits without slipping under load.
• 67/18 Primary Gear Ratio: Optimized for better low-speed performance and smoother takeoffs.
• Correct-Length Shift Shaft: No mods required—bolts directly into newer Honda-style engines.
• Includes Allen Head Bolt Kit: Clean hardware upgrade for the engine cases.

What You’ll Need:

You’ll reuse a few stock parts and add your own clutch perch and lever (sold separately). A clutch nut socket is required for installation—do not use a hammer or screwdriver to tighten the nut. It must be torqued properly.
