Frequently Asked Questions
Signs include visible cracks, splits, or hardening of the rubber; vacuum leaks causing rough idle or poor fuel economy; fuel smell near the carburetor area; or air leaks detected during carburetor synchronization.
The K&L 11-4851 is designed for specific applications. Verify compatibility by checking your motorcycle's OEM part number against K&L's fitment chart or consulting with a retailer's customer service.
It's recommended to replace hose clamps during installation, as old clamps may have lost tension or become corroded. New clamps ensure a proper seal.
K&L is an OEM-equivalent supplier. Their parts meet or exceed OEM specifications. The main difference is typically price—aftermarket parts are usually more affordable than genuine OEM parts.
With proper maintenance, a quality carburetor boot can last 5-10+ years or the life of the motorcycle, depending on environmental conditions, fuel quality, and storage conditions. Rubber degrades faster in extreme heat or UV exposure.
