I have a new set of standard pistion rings for the 550. Before I install them is there anything I need to do in preparation. i.e. is there a ridge at the top of the bore that needs to be removed, or whatever. Or can I just remove the old and install the new?

Check you bores to make sure that they are within spec. and don't need to be rebored. I would at least re-hone the cylinder walls if the bores are indeed within specification.Originally posted by Suzuki_Don View Post
It is essential to measure ring end-gap. Put the ring in the bore (press it in with the piston until the ring grooves disappear) and measure with a feeler guage the gap between each end of the ring. The spec should be in your manual. You can file the ring if the gap is too small with a FINE file. Make it right....not enough end gap and you'll probably sieze your motor.
Also make sure your compression rings are put in the proper order, with the proper edge facing up. Both top and bottom compression rings are different. This should also be in your manual. During installation make sure the "gapped" portion of your rings are not directly above on another when you slide them into the bores. -
Thanks Mark. Will there be a ridge at the top of the bore. And will this need to be removed. If the ridge if there will it break the top ring if it is not removed.Comment

There is no way to know if there is going to be a ridge until you take the cylinder off. The cylinders pull off from the top so the ridge, if there is one, will not hinder disassembly.Originally posted by Suzuki_Don View Post
As Mark said, have the cylinders measured. If there is a ridge you can measure how much.
I'd definitely hone first and pull the head apart to check the valves and replace the valve stem seals. It's well worth the effort to do the job right.Ed
To measure is to know.
