Open Face FG-JET Snowmobile Helmet Installation
Installation of Ear Noise Reduction Muff Kit in open face helmet model
Picture below shows 3/16″ pop rivet installed to hold metal chin strap in new location 1 5/8″ lower and forward of original hole.
Stitching had to be removed from chin strap attached to metal chin strap connector to helmet and was shortened about one inch. Strap was reinstalled on metal chin strap connector. Holes were melted into strap with soldering gun shown below.
Back side of cut out Styrofoam needs to be notched for new metal chin strap location that had to be repositioned lower on helmet so it would not be under ear muff.
Below is a picture of the small knife I use to cut out Styrofoam and plastic on side pad and to cut out side EPS Styrofoam.
