For you guys that have removed your valves without a valve spring compressor, howd you do it?  I saw a video on youtube and the guy used a socket then put a magnet through the sockets hole.  Then he pushed down on the socket and the magnets grabbed the keepers but when i do it doesnt work. When I do it the valve moves down to so the magnets cant grab the keepers. Any help will be appriciated

DO NOT DO IT!  A valve spring compressor is like 20 bucks on ebay, I bought one when I did my top end this past summer, best sawbuck I ever spent.

I cant find one for under $50 and dont really want to spend a lot on one if i dont need it because i dont have a ton of money

I think I got mine out one time by putting a rag under the head and sharply whacked the valve cap with a socket on top. The keepers eventually fell out. I then bought the tool to put new valves in.

If you do not need a valve spring compressor, why are you taking your valves apart?

 

Getting the apart is usually easy, it is getting them back together that is tough and near impossible without a spring compressor.

 

Hack repairs mean hack results.

Right now Im rebuilding my yz400f and the valves and head have tons of carbon deposits on it. So Im going to take them out clean them, then see if they need replaced

Not how you do it. Before you take the bike apart, you do a leak down test. That will tell you if the valves need work.

 

Disturbing the valves and 'set' they developed will certainly make a questionable valve fail.

so you think i should just leave them alone instead of taking them out and cleaning them up good

If you do, replace the seals.

I followed that video with my top end rebuild. It worked great. Just have a folded rag under the valves. Putting it back together is the hard part. I had my wife put the keepers in while I held the spring down. Also, dont get in a hurry. If you slip, you could damage the cam journal or the valve cover gasket area.

When you clean the valves, if using a bench grinder mounted brush, stay off of the sealing surface of the valve face.  DO replace the seals.
