Got my BGF 4 stroke,Sunn Cruiser going today. That.s 2 builds in 2 weeksLOL I'm so lucky.
Put about 5 hard miles on it seating the rings.
Realy impressed with how quiet it is.
Geared kinda tall with 3.25/1 chainbox and 11/48 secondary drive. Needs pedal assist on take-off, but slightly over 40mph top end so far.
I converted the chainbox to oil bath, so far, it is VERY quiet.
Couldn't help it ,I just HAD to try it with the muffler end removed. Sounded good,not too loud, /seemed to run a little better too. Gonna put it back tho.
