montesa 348 kick trouble Posted March 30, 2021 Report Share Posted March 30, 2021 (edited) Ozo shocks come stock with 12mm mountings top and bottom. How the hell do I change the bushings out for the top mounts on my mar. They are 15mm I’ve tried to contact PMK He’s done it. But I don’t know my way around this site yet. I wrote him all about it but the message wouldn’t send. It said someone else had my email address. Holly crap! So frustrating Edited March 30, 2021 by montesa 348 kick trouble Forgot something Quote Link to comment Share on other sites More sharing options...

stan wellback Posted April 1, 2021 Report Share Posted April 1, 2021 The shock mounts on an Ossa MAR are 12mm. you have the inner sleeve of an old shock corroded to the frame. hope you have not just painted it , it may need heat to remove it.

My OSSA also has the top mount larger than the bottom and it doesn't have an old sleeve still there Quote Link to comment Share on other sites More sharing options...
