2 Hard Kore Quiet Baffles, 2 Stainless Bolts & Nuts,  
1 Allen Key

Hard Kore Quiet Baffles are designed with strict tolerances.  We suggest removing any carbon deposits/buildup and any burrs inside the exhaust pipe with sandpaper, and placing a small amount of grease or WD40 around the outside of the baffle cap to aid the installation process if required.

Couldn't be easier.....
  • STEP 1  :     Remove exhaust end cap by unscrewing exhaust allen bolt with allen key supplied.
  • STEP 2  :     (See Fig. 1)  Line up hole on tab with bolt hole on exhaust pipe.  Tap quiet baffle into exhaust. The quiet baffle MUST be tapped in squarely – to check, measure from the quiet baffle to the end of the exhaust at several points around the exhaust pipe.
  • STEP 3  :  Replace exhaust pipe end cap and ensure hole in endcap, exhaust pipe and quiet baffle are all aligned.  Screw allen bolt into endcap and through quiet baffle tab hole. Tighten with acorn nut.

NOTE :  As with all motor modifications, some rejetting may be required.  The baffles may create a slightly rich condition in some circumstances.
