TUNED PIPE
CARB RESTRICTORS
• The SS .21 comes with a 7mm restrictor installed in
the carburetor.
• For increased performance, install the included 8mm
restrictor. The engine will need to be re-tuned after
changing the carburetor restrictor (richer mixture).
After extensive testing Steve O’Donnell has
developed the R2 tuned pipe for the SS .21. The
R2 tuned pipe helps the engine achieve maximum
performance, with a smooth, broad power band.
