STARTER
The standard XR50 engine is started using an external starter placed over the clutch fastening
nut (with a 22 mm socket) or started with an optional on-board starter.
3.8.1
OPTIONAL ON-BOARD STARTER
RENNtech’s optional on-board starter is intended for use in short start intervals. Under normal
conditions, the motor should crank and start almost immediately.
