98″ or 107″ Street Performer Nikasil Kit

T-Man Performance offers several kits referred to as “Nikasil Kits”, so we thought we would explain what we think are some of the benefits of using a Nikasil cylinder. The word Nikasil stands for Nickel-Silicon-Carbide and is one of the toughest, most resilient surface plating for cylinders on the market. When finishing, only a diamond honing stone can be used for final sizing because of the hardness of the plating. This same plating has been used in the aircraft, snow mobile, two stroke dirt bikes, NASCAR and drag racing industries for years with a stellar performance record. The upside of using our Nikasil kits is that you can run bigger bore sizes without having to bore your cases, +.060 per cylinder, in most cases. This is because the cylinders are not built with a cast iron liner. We offer 98” through 124” kits with our custom pistons (your flywheel stroke will determine your motor size). Our custom pistons run a lower ring tension which means less friction, making a cooler running motor that will make more power, rev faster and have a longer life span.
