has anyone on here rebuilt there kz 650 head?

If you have what can you tell me aboult it? Lance

They have small valves compared to a 900/1000 ,hows that? :woohoo:

Your Factory Service Manual will have the details/ Specs. But the Tools to do it correctly, will be much more money than sending it to a machinist. Unless you have the tools, or access to them and the knowledge, it would be best to pay a machine shop.

And be sure they know how to set up a shim style motorcycle head. Avoid automotive machine shops.

Ok so I'm looking for a shop to take my head to,I'm in Eugene.Oregon know of any one thats good and about what it well cost? Thanks Lance

Why not just box it up and send it to someone who knows what they are doing on these heads.

What Jay said X2

I'm looking for current project. So who is recommened for head machining? And what can one expect the cost to be? Thanks.

First off...you have to know what you have, is it good or bad? do you have the knowledge to know the difference? example, a low mileage motor might have a head where you could get away with hand lapping the valves back in, where as a high mileage motor might need a complete rebuild, what tools do you have? I use a big c clamp with a rubber piece on the end, 10.00 usd, a piece of pipe with the sides cut out to remove or attach keepers. Setting the head up on its side, pour some solvent into the intakes, is a good start to know where you are, also exaust, if you find solvent leaking around the valve it needs work. Read, learn, and do what you can, farm out what you cant, otherwise bend over and let the motorcycle fleecers get you credit card, or atleast hold your wallet! :laugh:

Thanks, funny. Haven't even had a chance to look yet all I know is 19k miles and sitting for at least 10 years... I just remember in college my buddy telling me about getting the head ported and polished on his new to him 280Z and how night/day it was sooo... I know little but like to read much.
