Been awhile since I had a 4-wheeler. Been involved in other activities such as Fishing, Hunting, Riding my Harley. Wanted to get another 4-wheeler to Ride with my SIL, Daughter and Grandkids.

Found a nice barely used 2007 Sportsman 700 EFI and brought her home.

First question, I put 87 Regular Gas in it (after draining the tank dry-Bike had been sitting for 3 years) and it seems to ping-knock some. Manual says 87 min. Should I go to a higher Octane? if so what?

87 is the ONLY non-ethanol gas around here.
