Hey Scott,
Your Corbin looks bigger that mine around where the butt resides. I've seen all different configurations of Corbins. I've got one for my R90 that has no butt cup at all. I rode that one for well over 100,000 mi. until the cover rotted away.
Don't know if I will use this one for a lot longer though. I can put the money I get for it towards the Russell....(Don, great idea).
I rode around today with the new handlebar adjustment (lower) and it was better than before... :clap:
Will I still be able to use my heated grips on another handlebar (K75c or K100 Standard) that wasn't made for HG's ? I think I have to drill somewhere...??? This is all new to me, so I apologize if this question sounds really, really stupid.
