I just used an oil filter wrench - the band type - for a ring compressor last night. I drilled out the riveted pivot pin and replaced it with a nut and bolt which allowed me to withdraw the wrench after I slipped the cylinder over the piston.

 I was working on replacing my head gasket. I pulled the
cylinder to check it's condition and replace the base
gasket while I was there. While reinstalling the
cylinder, my rigged ring compressor slipped, and I broke
my top ring. Needless to say, that was an hour ago and
I'm halfway through my 3rd beer and still friggin' pissed
off.

My questions are:

1. Does anyone have a used 949cc (87mm) top piston ring
for a set of sleeved cylinders they'd let go of
reasonably?

2. Is there a way to ID these cylinders and pistons? No
markings at all on them. The cylinder is iron sleved and
the piston is flatter on top that a factory one. 3 rings.
It was installed at Cycle Specialties in Athens, GA about
10 years ago...any clue what they used?

3. My chilton's book says the cylinder should slide over
the rings easily when compressing by hand. Didn't work
too easily for me, so I got the hose clamp out and screwed
up things more. Is there an easily obtainable ring
compressor tool that will work on a Guzzi? I guess one
for a VW would work since they are very similar.

Please help me! Got awesome riding weather and a broke
bike! I'm gonna go into DT's if I don't ride soon!

Thanks!
