V-Factor Stock Replacement and Big Bore Piston Kits
Hazelwood, Missouri based Mid-USA Motorcycle Parts continues to add to its V-Factor performance components line with these OE replacement and performance upgrade pistons and piston kits.
For 1200 cc Evolution Sportster conversions, V-Factor cast pistons have moly coated skirts for performance and longevity. Sold as pairs in kits, they include wrist pins and wrist pin keepers.
They are available for 1986 and later XL applications in standard 3 1/2" or +.005" bore; for 2009 and later applications 1200 cc cylinders must be used (available separately) as the OEM cylinders cannot be bored to 1200 cc.
For 93 and 103 ci Big Twins, V-Factor replacements match factory specifications and compression ratios. Features include moly coated skirts and kits include wrist pin and clips. Sold singly.
They are available for 96 ci 9.2:1 compression ratio standard bore applications from 2007 and up; for 103 ci 9.7:1 compression ratio applications from 2007 to 2016, they are available in choice of standard bore, +.005", +.010"or +.020".
V-Factor cast low compression pistons (enabling the use of pump gas without detonation) that meet or exceed original equipment specifications are also available with moly skirt, piston pin and lock rings for a wide range of additional applications such as 74 ci – 1200 cc 8.51:1 standard compression ratio for Panhead and Shovelhead applications in a range of sizes from standard 3 7/16" bore right out to +0.70" bore.
For 80 ci – 1340 cc Shovelheads in 8:1 standard compression ratio from standard 3 1/2" bore out to +.050" and for low and standard compression ratio Ironhead Sportsters 54 ci – 900 cc (1957-1971), 61 ci – 1000 cc ('72-'85), and 74 ci – 1200 cc Sportsters ('88-'03) - all in a selection of bores from standard to oversize.
