Part: Honda CL / SL / CB350 CL / CJ / CB360 Intake & Exhaust Valves Kit

Why You Need This: There is a lot of internet talk about doing a "top end" overhaul on your Honda CL / SL CB350 or CL / CJ / CB360. A proper top end overhaul not only involves refreshing the cylinders but going through the cylinder head and inspecting the valves, valve guides and the the whole valve train. Intake and exhaust valves do wear out with high mileage and should be replaced if they measure out of specification. Our valves are high quality stock replacement units Made in Japan and sold as a kit, with two intake and two exhaust valves. While you are replacing the valves it is also a good idea to measure the valve guides and replace if out of specification. Now you can put it all back together with a fresh set of overhaul gaskets, intake and exhaust valve guides and get your bike back on the road.

Installation Tip: Valve seats need to be cleaned up from a machine shop or you need to be lapped with the new valves. Guides must be measured for excessive play / wear. Honda CL / CJ / CB360 models use valve stem seals, that should be changed when the valves are replaced if you are still using the factory style iron valve guides.

Brand New Vanilla Valves
Nothing fancy, just new & great to replace once you have to top end of your 350 twin cracked open. Came on time, as I ordered them. Had my local shop do the lapping, have had 0 issues since(3k miles). Hopefully they last a good long time.

I had nearly no idea what i was doing
Nice looking valves! I don't know much about 4 strokes, but these looked a lot straighter than the valves I took out. I have a lot of experience with small vintage 2 stroke mopeds, and some of them have decompression valves so i figured this was just a larger version of that. Boy, was i pretty much right! Lapping was pretty straight forward, probably spent about an hour and a half to two hours total doing all 4 using a drill and cup from one of the valve lapping sticks. I did use the stick a little bit just to pretend i was a cowboy lighting a fire on the range. I did not cut the seats. The motor i was working on only had 16k miles on it. I just removed the pitting and made sure the seats were even. Started with some Permatex Valve grinding/lapping compound from Autozone and finished with some 280 Grit Loctite Clover. It is hard to find lapping compound finer than the 280 for a reasonable price, but i think 280 is fine. I have never worked on an engine with valves before. I did just fine. I checked the valves for leaks by cleaning all the lapping crap off, creating a seal with my lips on the head and blowing on the valve i was lapping. You can tell when they are not sealed. Used a C-clamp and a cut socket to install the springs and keepers. It was kinda terrible and i recommend getting a proper valve spring compressor. Certainly doable though. You can see i scratched my mating surface a hair. It buffed out. Good valves! Very recommend. Made in Japan!
