Following news last month about Kibblewhite ' s valvetrain system for the Indian Scout , this month it has released details of a spring kit , guide and White Diamond valves for the 2020-2022 Indian Challenger . The Racing spring kit with 0.520 " lift capacity is " specifically designed for all Indian Challenger applications and offered with dual springs and lightweight H . T . steel retainers for an increased spring rate and higher lift compatibility over the stock components . " Our ' Engine Builder ' manganese bronze valve guides have been designed with the price-conscious builder in mind . Expect the same exacting KPMI tolerances , but with a reduced toughness / wearability when compared to premium C630 nickel aluminum bronze valve guides . " Available in standard / stock and oversized , the softer manganese guides are easily reamed , and then can be delicately finished with our high-quality ball hones .
Experience the Edge
Utah based Kraus Motor Co has added to its ' Apex ' product line with these new SS3 universal ' Apex Edge ' lightweight , aggressive looking aluminum footpegs .
Now , with any battery-operated or electric drill , you can ream and hone manganese valve guides in less time and in the absence of expensive honing equipment required to properly size tough nickel bronze guides . " Our White Diamond valves , available in standard and 1.0 mm o / s head diameters , are fully CNC-machined from a one-piece forging of either EV8 stainless steel or Inconel-751 . These materials have proven heat and corrosion resistance properties . Each valve is designed using Finite Element Analysis software , and profiles are tested on our computerized flow bench . Strict attention is paid to the surface preparation of the valves , and the purity of the chrome is closely monitored . " A 360-degree anode is used to produce the highest possible grade of hard chrome finish . White Diamond valves are light , strong , one-piece forgings with profiles that provide excellent flow characteristics ."

Designed for aggressive comfort , ' Apex Edge ' footpegs will " plant your feet on a solid platform for increased stability and control . The serrated finish increases traction - offering increased confidence deep in the corners ."

Fitments include selected Dyna , Softail , Sportster , FXR and Touring models .
Available in Europe through Zodiac International , this stainless steel muffler with SuperTrapp ' s 5 " tunable disc system comes with 22 pre-installed discs " for a deep , low tone rumble " on Harley ' s Pan America Adventure Tourer . It comes with an S-bend connector tube and all the necessary hardware to bolt it straight onto the stock headers . The complete slip-on muffler kit is around 2.5 kg lighter than the stock exhaust . The SuperTrapp tunable disc system allows you to adjust , or “ fine tune ,” the sound level , powerband and performance . SuperTrapp discs also provide a scavenging effect - the gap between each disc ranges from . 023 inch ( 0.584 mm ) wide on the inside of the muffler to . 028 inch ( 0.711 mm ) on the external open edge . As hot exhaust gases pass through the discs to exit the muffler , they enter a larger area , creating a slight pressure drop as the gas expands , creating a scavenging effect for the hot gas still inside the muffler . Adding discs increases the size of the exhaust outlet , increases exhaust flow and exhaust tone , while reducing backpressure . More discs move the power band up to give more top-end power and lean out the fuel mixture . Removing discs decreases the size of the exhaust outlet , decreases exhaust tone and exhaust flow , while backpressure is increased . Fewer discs tend to increase lowend torque and make the fuel mixture richer . The tunable disc system also allows you to compensate for changes in altitude and air temperature without rejetting or changing the air intake .
