I found these on eBay. Anyone used these valves? It's a great price, made in Japan, and the seller has 100% positive feedback.

6x VALVE-Intake Set for Kawasaki Z 1300 12004-1004

yes Stan i just fitted a full set with no problems

So I have to ask,
who manufacturer these valves?
Are they chrome stems or nitrided?
did you happen to measure the margin? If so, what is it?

I need valves for my project and plan on getting Ferrea Valves in Fort Lauterdale USA to custom make them for me. This way I'll know what material they were made from and at the same time accomodate some fitment issues I have with this cylinder head. Stay tuned. The only issue may be due to Irma landfalling in Fort Lauterdale, so we'll see if they reply to my email next week.

Great Kiwirider! I just took my valves out. A few of the intake valves have a lot of surface pitting and I want to replace them.

Kawboy. Looking forward to the follow up. These valves from eBay, if good, would be a great deal. I am still looking for options. It is better to spend a bit more but be sure of the quality. So more research in progress before I press the 'buy' button..

Kawasaki dealerships don't have intake valves. Exhaust are about $65 Canadian each. I got an email from Helmut and he has stock intakes for 45 Euro each, or aftermarket for 25 each. So these on eBay, a set of 6 for $114 US, is a great price. They are sourced from a dealer in Germany, but it says made in Japan. I am wondering if they are the same as those Helmut offers. Oem are too much for me at this stage.

Other than that, I don't know any technical details.

I would guess those valves are Vesrah. Really the only intake valves left for these bikes are left over Vesrah stock.

I had to get a set from z-power.co.uk as none could be found in the US.

Should have no problems with them.

Sorry KB i cant answer those questions i don't have the paper work ive have sold both me 1300sand passed on the receipts. I was so pissed off with the problems i was facing all the time and the money i had pumped into it i wish i could have taken the seller to court but too big a time delay to do any think though eBay i hope other people don't get burnt like me
