Making the BMC Mightier
One of the bikes that rotates from staffer to staffer at our office is an ’02 BMC 918ST. The 918 came to us equipped with a potent and hard running, stock 100ci RevTech engine, but after piling up about 10,000 miles, we decided it was time to open the motor and shake things up a bit. The goal for the changes we had in mind was additional torque, especially in the low-to-mid rpm range.
Components for this hop-up would consist of the following: a RevTech 2-into-1 tunable exhaust system designed to boost the low-end torque, a Headquarters HQ-0026 camshaft, Andrews adjustable pushrods, and a Mikuni HRS 45 carburetor designed to supply the motor with all the fuel it might need.
