this is a NICE forum and website, hope you all can help. I have gone through the second (used) factory showa shock on my 1983 interceptor. My questions to others have been can these adjustable air/oil shocks be rebuilt, and is it worth it? I have also been told that with simple modification that i can use a much newer shock off of a CBR Honda, or of of a Newer VFR. Can anyone offer me some guidance on this, the old shock is just hard as a brick with VERY slow movement! Thanks
