We are going to follow DougE's
suggestion and replace our BR engine
oil tomorrow, with a quart of Bel Ray synthetic blend Scooter 5W-40 oil.
We spent a few days at Daytona Bike Week Thur - Sat
and visited the Bel Ray company display. Speaking with
their Chemical Engineers they actually were familiar with
the BR and they suggested their synthetic blendScooter
5w-40 oil for the Big Ruckus.
It's blended for all 4 stroke scooter engines with liquid or air cooling and
wet clutch systems. The bottle has "SCOOTER"
in 1" letters, running up and down on the front of the bottles. (belray.com)
Hopefully, installing exactly 1 quart will stop the occasional oil
drip our BR is experiencing on the L rear side.
