Valve Inspection - Orings

I'm doing a valve adjustment and just curious if you guys replace orings you encounter during a job when you do maintenance? Also, is there a better way to buy them instead of from dealership/suzuki online? Thanks for the feedback!

They don't have o-rings on the valves...They do have valve stem seals...but you would need to pull the valve keepers, springs etc to do it. So you would need to put in a spark plug air hose adapter to keep the valve closed while you did it or pull the head and do a full head job.

Depends on the bike and condition of the gaskets and o-rings.
What bike do you have and how many miles are on it?

Depending on exactly what seal it is and material I would say you should do one of two things. If you plan on reassembling it and don't want to pull the valve cover of for many thousands of miles than just go ahead and replace what seals and gaskets you can while you have it apart. If you plan on doing more maintenance in the near future or enjoy wrenching on your stuff you could try and get the max life out of everything. Just be prepared to turn a wrench if needed.

Do extensive research on your application however for there may be a gasket or seal which after disassembling will not quite seal the same again and will need to be replaced.

As stated above you don't have to worry about your valve seals... Unless they are damaged and you are finding oil in the ports/cylinder.

Thanks Patrick. It is an "antique" 06 GXR 600 with 38k miles (I bought it brand new). 6 of my exhaust valves were out tolerance, the rest were fine. I am not doing a full cylinder head/valve job, just meant for example the orings on the oil jet(cam chain tensioner), and the orings inside the sparkplug tubes(where the journal holders fit into), etc. I think I will go ahead and follow service manual instructions and just replace whatever orings I encounter during maintenance to make sure I get a good seal.

Thanks for feedback. I am definitely replacing all the gaskets I encountered (cylinder head cover, journal holders), just meant the regular orings. I do enjoy wrenching on my stuff. I use to work for an oil/gas company where not replacing a $1 oring could compromise a $250k tool, so I figured the same concept should apply to my motorcycle

No problem. That's just my opinion. Just as you said about plant work I apply to engines. I've debated this forever with guys on motor builds. They buy a Callies crank, Diamond pistons, Jesels VT and then go and be a Cheap A$$ buying bearings and seals and cheap oil system parts. Why toss thousands upon thousands of dollars in nice parts just to risk them with cheap bearings and poor oiling. You already have 15k in the motor put another $300 to buy good stuff. As you said $1 dollar here can be $1000 dollars down the road when that $1 fails.

Good Luck
