Aftermarket Valves from "Japan"?

14 Jul 2015 17:44

No eBay APP ID and/or Cert ID defined in Kunena configurationAnyone have experience with these valves? They're a fantastic deal:

I did some digging but couldn't find anyone conversations about them. Supposedly they're made in Japan and the distribution through that ebay store is out of Germany but I've seen what looks like the same exact valves coming out of Australia as well. A set of 8 comes out to about $17 apeice, so it's a huge savings over OEM if the quality can come comparatively close.

Just wanted to see if anyone had two cents to chip in!

After finding out I had three bent valves... I went out of my way for a few days until I found a NOS OEM set and I paid no more then $27 for any one of them.

I have a lot of used valves. Never hurts to have spares. I broke a timing chain once and needed a set and had to buy a head to get a set.

Ask who makes them. I bought a set of Doremi valves made in Japan. They were lighter than my stock ones so I wasn't sure about them. Couldn't find any bad reviews and no problems so far.

After finding out I had three bent valves were these taken from a running engine? the reason I ask is they can be very slightly out and it isn't obvious.

No, not running. Not really obvious either. it was a spare head. I poured thinner into the ports and watched three of valves weep or drip fluid out of the them. I took it to an engine shop and they V blocked them to show me the valve heads were wobbling quite a bit when turned under a micrometer.

I don't recognize them but I recall I got all new valves for my 750 from RustyRidersLLC and I think the brand was Vesrah but I never paid more than $20 for a valve.
