Description
Fed up of looking at fuzzy white or crusty green factory bolts? This custom UK-made stainless steel engine bolt kit provides the crisp finishing touch your modern liquid-cooled V-Twin deserves. These are not just for show; they offer massive practical advantages over the standard mild steel originals, which are highly prone to freezing fast inside the aluminum block due to local winter dampness. With high-tensile stainless steel, you get easier maintenance access, zero paint stain worries, and a cleaner-looking engine case built for the long haul.

🔧 Install Tips
- Torque Spec is Highly Important: Never brute-force or overtighten these fast bolts! The required layout torque for screws sliding directly into soft alloy side engine casings is very low—cap your settings to around **6 ft-lbs / 8Nm MAX**. Always use a light mechanical torque wrench.
- Swap Method: Keep the side gaskets sealed by pulling out one old factory screw at a time. Clean the open engine threads gently with a cotton bud to lift old oil mist, then drop in the fresh matching bolt.
- Use Anti-Seize Paste: Squeezing a very tiny dot of copper or nickel anti-seize compound down the thread lines is highly recommended if you commute on local roads during salty winter freeze cycles.
