Our take on the Twin Power 81-Up XL models Black 1.4 Kw Starter Replaces H-D 31390-86 31390-91F

A new, not remanufactured, 1.4 kW starter for 1981-and-up Harley-Davidson Sportster XL models, replacing H-D part numbers 31390-86 and 31390-91F. It is a direct-fit replacement for the stock starter on carbureted and early EFI Sportsters, from the XL883 through the XL1200 family. The 1.4 kW rating matches the stock output, so it is a repair part rather than an upgrade. Buyers get a new unit with a limited lifetime manufacturer's warranty instead of a rebuilt starter, which is the main reason to pick it over a used or remanufactured original.

Questions and answers

Which Sportsters does this starter fit?
It fits 1981-and-up Harley-Davidson XL models, including the XL883, XL1200C Custom, 1200 Low, Nightster, Roadster, Forty-Eight, Seventy-Two and SuperLow 1200T. It replaces H-D part numbers 31390-86 and 31390-91F.
Is this a new starter or a rebuilt one?
It is 100% new, not remanufactured. Twin Power backs it with a limited lifetime manufacturer's warranty.
Does the 1.4 kW rating mean more cranking power?
No. It matches the stock 1.4 kW output, so it restores original starting performance rather than upgrading it.
Will it fit a fuel-injected Sportster?
Yes. The listed fitment covers EFI models such as the 2007-and-up Forty-Eight and 2014-and-up SuperLow 1200T, along with earlier carbureted XLs.
What is in the box?
The starter itself. Reuse your existing mounting bolts and gaskets unless they are worn.
