I checked out the kips on a bike I purchased recently and found the right side (when looking into the exhaust port) valve doesn't turn, but the other two are working fine. Before I dig in to replace parts should I purchase the valve and have it ready to install? Is there any hope it can be repaired or is it surely a stripped/broken gear? I already have the kips o rings on the way so I'd just like to minimize the down time by having parts ready to go. I understand I may find the other valves to be in bad shape when I tear it down.
It sounds like, if you want to be prudent with spending, you should tear the top end down and see what you are going to need before you order the parts.
