Hi everyone , i have a tech question , i have a 83 750 cc DOHC Honda engine , with the stock gearing at red line ( 9000 rpm ) it tops out at about 130 mph , by replacing the sprockets with 18 teeth on the front and a 34 on the back my calculator says that should be 160 mph on the top end , by replacing the 16 inch tire with a 18 it should be 175 mph , i need more than that , any one here know if the gears out of a 78 750 k touring Honda 4 SOHC will work in the DOHC trans, " my 78 Honda SOHC ran about 160 mph at 8500 rpms with the wiseco big bore cylinder , wiseco racing pistons , cam and standard gearing
", or where can i buy taller gears or a primary for the DOHC engine .
thanks
Keith
