I'm doing a lot of work on my 82 CB650SC. One small thing was removing the garbage grips some PO installed that were falling apart and replacing with the original Honda grips. After removing the old grips and taking a look at the fiche for my bike, I'm realizing that I think the whole handlebar weight setup is missing. I'm not sure if they had to be removed for these non-Honda grips to be installed.
My question: When installing the new original Honda grips, is there a solid reason to get a new set of handlebar weights? I don't think I noticed a lot of vibration when the bike was running well. So do I have a good reason to spend the extra $?
