My 1999 Royal Star Venture gets an average of 45 miles per gallon.
it get 20 mpg
As of 2002 Gm increased their fuel pump capacity by 30 %.i believe 13 miles a gallon is accurate
If the bike is in decent shape, you should expect to get at least 50 MPG.
I can't think of any that wouldn't fit. The 1986 to 1993 bikes are virtually identical except for colors.
It depends on the length of the van. The "short" van is supposed to hold around 20 gallons in the tank.The "long" van is supposed to hold around 25 gallons.
