[QUOTEMD"swooshdave, poste: 434063, membre: 1298"] Vos problèmes étaient que les verniers sont une mauvaise conception, c'est que vous les avez obtenu du mauvais fournisseur.
Et non, ils ne sont pas tous les mêmes. Ne faites jamais cette supposition. [/QUOTE]
Some years ago I mistakenly fitted REAR main rubbers as the front buffers and this made the bike much smoother especially from about 2500rpm. These rear rubbers are the same width but slightly smaller diameter to normal front buffers. I have now done the same on my '72 750 restoration and the bike is very smooth from much lower rpm. I guess that there is more engine shake at idle tickover but I don't do that often now and appreciate the much better smoothness at low rpm. I guess this is only possible on the old shimmed isolastics having separate rubbers.

Before I replaced my front ISO's, the bike was dead smooth through the rev range . That was because the rubbers were nearly non existent and I had some metal to metal contact on the overrun. Now the bugger vibrates through the bars up to about 60 mph.
TopgunPeter. You have made my day. Rear iso rubbers in the front for me from now on. I even spoke to Hobot about the problem. Maybe I can do a Bert Munroe on them.
