Got the bars on today, shouldn't have worried about getting the old grips off as I was able to pull them straight off, no messing with screwdrivers and WD40. I put some Renthal medium grips back on, much smaller diameter, my plan of sticking the grip puppies on them is slightly flawed due to the fact they've been stretched by the heated grips, hopefully they'll shrink back a bit, time will tell.
I haven't cut the bar, thought I'd see how it was for the time being, easy enough to shift things along the bar though if I do decide to.
Only had a very short ride but it feels good, will be having a long ride back over the hills tomorrow so that'll be a good test for comfort.
Cheers,
Rob
