Resali 11 Posted March 30 Share Posted March 30 Hello knowledgeable people For my birthday yesterday (yeay me ) I was given a new radiator guard for my NC750S. In preparation for the fitting, I noticed that the radiator is secured with one bolt on the left of the bike, but there does not seem to be one on the right. Surely there should be a bolt on both sides? Pictures below. Does anyone know what kind of bolt I need and where to get it from? Many thanks in advance for your help. Link to post

If you check the (bolt-less) right side mount you'll find that the radiator's rubber bushing sits over a tubular projection on the bracket. The bolt on the left side is effectively trapping the right bushing in place. If you feel you need to, the nut/bolt pair are the same as the one that is there - 10mm x 30-40mm (measure the existing bolt to be sure). 1 1 Link to post
Tegraman 765 Posted March 30 Share Posted March 30 (edited) Manufacturing discrepancies and expansion/contraction might stress the radiator if both sides were bolted. If one side is secure, but still free to "float" slightly, no stressing can occur. Edited March 30 by Tegraman 3 1 Link to post

They're through holes in the radiator lugs and act like shock absorbers, allowing some free play. Link to post

I’m glad I checked now. :-) 1 Link to post
