Product Overview
The sprag clutch assembly on the Royal Enfield Electra X has been known to fail under certain conditions. As repair of the sprag clutch is an expensive option it is advisable to take any measure that may prevent or reduce likelihood of failure.
One cause of sprag clutch failure is engine kickback. A kickback forces the engine in a reverse direction. As the sprag bearing is designed to rotate in only one direction an engine kickback puts excessive stress on the bearing often resulting in its total collapse.
On certain Electra X engines electrical noise interferes with the engine’s electronic control unit. This leads to the ignition unit producing an additional, rougue spark - giving excessively advanced ignition timing. If the engine has not achieved sufficient forward momentum the advanced ignition causes an engine ‘kickback’ with sufficient force to destroy the sprag clutch.
To minimise the risk a spark delay unit can be fitted which allows the engine to achieve sufficient forward momentum before ignition occurs. The spark delay unit is easily fitted and inexpensive
