To fit the Coucours ABS you can get them here:
They're identical to the grip puppies; just by a different name (many more companies sell the same thing). But if you don't have to cut them, then I'd get those instead. Even if you're super careful, the cuts will never be perfect.
And thank you for the rubbing alcohol tip. If they don't move, it's less messy than with extra-hold hair spray (liquid, not aerosol). I already have the hair spray, and with that, they're set for life. You could remove them, but only by tearing them apart. And yes, the heated grips work perfectly. And they reduce vibes transmitted to the hands. With a bike like the Connie with a riding position not exerting any pressure on the hands, they should work beautifully. That will be one of my first mods, along with a black-series TBR M5 with the P1 quiet insert, CooperDawg sport screen, radiator screen, fender extender, throttlemeister (heavy in black), and remove reflectors and 'kawasaki' letters from the side panels, and all that ABS/TRAC white crap from the front fender. Hope I don't have to mess with the seat, but will use the bike for at least 1K miles before rendering final judgment. Have a good one.
