Warmed her up good with a 15 minute ride.
Drained the oil bag.
Removed and replaced the filter.
Added 3 qts of oil.
Ran the bike to get the oil through the engine and filter.
Checked the dipstick, right to the top of the full hot mark.
Figured maybe i needed to run it a bit more.
Took it for a short ride, checked again, same thing...
My book also says 3 1/2 qts???
