MAINTENANCE

Exhaust System Restrictor

The exhaust restrictor system restricts

exhaust gas flow, reducing the maximum

power output of the engine.

Exhaust System Restrictor Removal

The Scrambler 50 utilizes a restrictor at

the headpipe exhaust flange

and

at the

spark arrestor.

Make certain the engine and exhaust

system is cool to avoid burns.

Loosen the set screw (A) of the exhaust

restrictor on the spark arrestor and remove the exhaust restrictor.

Remove the nuts at the headpipe exhaust flange, the center mount bracket bolts,

and the spark arrestor fasteners.
