1988 CBR Hurricane boggs between 4-5K
I just purchased a 1988 CBR 600 Hurricane. The bike starts fine and stays runing good. Exellant pickup above 5,500 RPM. However, no matter what gear I am in, (realy obvious in 1st, 2nd and 3rd) the motor bogs down as I Accelerate starting at 4K rpm till I reach around 5,500 rpm.
The first thing I did after buying the bike was I ran the tank dry and filled with 92 with a bottle of Gumout. Ran that through but no improvements. It also has a Vance & Hines Performance slip on.
Thank you in advance!
