Anyone have experience with these valves? Different in that the face of these isn't flat - has a relief with 'Made in Japan' cast on the face. Made by Japan Engine Valve MFG. Co. Ltd a Nippon Seiki company. Price was right from a Canadian supplier. A poster on the CB1100F forum suggests they're as good as OEM and fine for a street bike.

They're fine for a stock, street bike. I've used them in the past and wouldn't hesitate to use them again. The only downside is that they're a little harder to lap, due to the lettering on the end. (as you mentioned).

Thank you! I'll proceed with these.
