These bolts are the cleanest way (no more ugly hoses) to solve the potential crankcase venting issues you may encounter when installing an aftermarket air cleaner.
They are fully CNC machined 6061 aluminum that is polished for a super clean look. The set includes stainless steel vent screens, stainless washers, circlips and foam filter elements. For your 1991-UP Sportster & Evo Big Twin Harley motor. Made in the USA. Pair: $49.99. At TC Bros Choppers. Tel: 419-654-8747.
so if you have crankcase pressure issues this will be wonderful weepers… its obviously not their problem , but you’ll find out quickly if it may be time for rings…
I guess they are a great way to stop your bike from rusting in the dead of winter.
Seems rather spendey for two hollow bolts, circlips, and foam. $50bucks for $5 worth of parts and labour is a lofty, But is is a novel aproach.
I’ve had similar (another mfg) installed on my Sporty for several years, with zero issues. Mine are polished stainless, and look much nicer than these.
