Part: Honda CB450 / CL450 / CB500T Intake and Exhaust Valve Guide
Why You Need This: Honda has a reputation for building bullet-proof engines but still, thousands of miles and 40 plus years later, the time for a complete overhaul might be due. If it's the cylinder head you will start working on first, you will need some of our high performance, bronze valve guides to replace the old, worn-out ones. For the Honda CL450 Scrambler / CB450 and CB500T the valve guides are the same for intake and exhaust. Guides are sold individually and four guides will be needed to rebuild a cylinder head. While you are at it, change that old cam chain too and seal everything off with an overhaul gasket kit. You'll end up with an engine ready to go another 40 years.
Installation Tip: The valve guides need to be installed professionally with a proper driver. Guides will need to be honed to the proper 7mm inner diameter once installed in the head. Valve stems need to be measured with a micrometer to ensure their wear is withing factory service limits. Valve seats should be lapped or ground during rebuild.
