I'll know how good we can get this R1100R later in the week. I am in NH now and would love to try the Beta when it's back. I don't have any add-ons to improve this bike yet as I have only owned it long enough to ride it about 450 miles (bought just before snow here. I have no way to know but only 6,000 miles in 14 summers may be due to this issue. I will try to contact the origional owner to find out if it surged from the beginning or if I am seeing a new issue. Feel free to PM me if that works for you.
