Abstract:
This topic aims to increase the capacity of engines used in dragbike competitions.
Motorcycle engines used in dragbike competitions require significant modifications to
achieve maximum and optimal engine performance. One factor that greatly affects
motorcycle speed is engine capacity. Engines with larger capacities tend to have faster
acceleration, while engines with smaller capacities have higher maximum speeds and require
more time to reach the desired target speed. Some of the main components for increasing
engine capacity are modified: the camshaft, crankshaft, changing the cylinder head angle,
piston, valve spring, valve, and other supporting components such as CDI, power up, drive
pulley, rollers, CVT spring, double clutch springs, and double clutch bowls. The dyno results
after several spare part replacements showed a torque of 35 Nm at 9500 RPM and 47 HP at
10.000 RPM.
