Caltric Valve Stem Gasket for Suzuki DR Z400 and DR250 SE 8.5x10mm

Description

Product Overview

The Caltric valve stem gasket is engineered specifically for Suzuki off‑road motorcycles, delivering a precise fit for the DR‑Z400 model years 2000 through 2004 and the DR250 SE from 1990 to 1995. Constructed from high‑grade, oil‑resistant rubber, the gasket forms a reliable barrier that prevents fluid escape while tolerating the high‑temperature environment of a running engine. Its dimensions—8.5 mm width, 10 mm length, 4.5 mm inner diameter, and 8.0 mm outer diameter—match the original equipment specifications, ensuring a seamless replacement without the need for additional machining or adjustments. The material composition combines flexibility with durability, allowing the gasket to compress evenly around the valve stem and maintain a consistent seal over the life of the motorcycle.

Beyond the core sealing function, the Caltric gasket incorporates a proprietary compound that resists degradation from gasoline, oil, and coolant exposure. This resistance extends the service interval, reducing the frequency of part replacement and lowering overall maintenance costs. The product is supplied as a set of four gaskets, providing sufficient coverage for both intake and exhaust valve stems, and includes a brief installation guide that outlines the correct torque settings and cleaning procedures to achieve optimal performance.

Usage

When installing the Caltric valve stem gasket, begin by removing the existing gasket and thoroughly cleaning the valve bore to eliminate any residual debris or old sealant. Apply a thin layer of high‑temperature engine oil to the gasket surface to aid in placement and to enhance the initial seal. Position the gasket carefully, ensuring the inner diameter aligns perfectly with the valve stem and the outer edge sits flush against the cylinder head. Tighten the valve cover bolts in a criss‑cross pattern to the manufacturer‑specified torque, typically around 20 Nm, to avoid uneven pressure that could distort the gasket.

This gasket is ideal for both routine maintenance and emergency repairs. Whether you are a seasoned mechanic performing a complete engine overhaul or a hobbyist conducting a quick valve stem replacement, the Caltric gasket offers a straightforward installation process that minimizes downtime. Its robust construction also makes it suitable for high‑performance riding conditions, such as off‑road racing or aggressive trail riding, where the engine is subjected to rapid temperature fluctuations and increased vibration.

FAQ

What makes the Caltric gasket different from generic alternatives?

The Caltric gasket uses a proprietary rubber compound that offers superior resistance to heat and chemicals compared to standard aftermarket options. This results in a tighter seal and longer service life, especially under demanding riding conditions.

Can I install the gasket myself, or do I need a professional?

Installation is straightforward and can be performed by anyone with basic mechanical skills. The included guide provides step‑by‑step instructions, and the gasket’s design eliminates the need for special tools beyond a torque wrench.

Is this gasket compatible with other Suzuki models?

The gasket is specifically sized for the DR‑Z400 (2000‑2004) and DR250 SE (1990‑1995). While it may physically fit on other models with similar valve stem dimensions, we recommend using the exact part number for optimal performance.

How often should the gasket be replaced?

Under normal riding conditions, the gasket should last the lifetime of the engine. However, if you notice oil leaks, reduced performance, or after a major engine overhaul, replacement is advisable to maintain a proper seal.

What is included in the package?

The package contains four valve stem gaskets, a concise installation guide, and access to online technical support for any questions you may have during the replacement process.
