After working on and building many brands of karts, I welcome those pricy little Birel clips. I wish every kart used them.
You will break countless bits trying to drill bolts, then ruin every nylock you put on that drilled bolt. When you snag an arm on a cotter pin or safety wire, you’ll be more than glad to pay that dollar a piece for that little clip.
I think of it this way. If I bought a set of new clips every year we’re talking about less than a $20 bill.
To me, that’s a pretty fair price for the easiest clip in karting.
