Decision Time
There are several motor parts that are used only on that year. If you try to buy any parts with a -89 part number for the motor, you will find they are obsolete. Harley did it the next year (1990) because of the problems.
Besides, the later year model you can get for the money, the better. And the 1997 has the newer wiring plugs that make most electrical parts just a "Plug-N-Play". Plus the EVO is from the last years and is, IMO, better than the earlier EVO.

If you check the Harley Part Catalogs for 1987-1990 (I have it along with one issued in 1989) any motor part using the "-89" part is obsolete. It has been replaced with the "-90" part.
I bet that if you took any 5 piece crank, it would fit the 1989 cases. But some connecting parts changed and would not work on the pre-1989 motor without modifications. If your motor had a 5 piece crank, it may have been changed.

I did like the list of mods on that heritage though, especially that small bit of red bling they added to the right side of the bike
Had an issue with it coughing through the carb under light acceleration so after checking all the ignition side decided to replace the intake gaskets for good measure and see how the carb was set up ... remember the previous owner just had $2500 worth of service/tune up done at the dealership less than two months ago.
Findings ... Stock carb mixture screw was 3 turns out, on disassembly we found it was running a #48 Low speed and a #175 High Speed also had a NOKM needle and the slide had been drilled to 1/8", float level was at 0.49 ... so got to wondering how/what the heck did HD of Dallas do???
Anyhow so I call a buddy over tell him to bring his magic carb box with him and we rebuild this thing including a new slide and stock needle. Set the float to .433 (11mm) shim the stock need 0.050, install a #45 Low Speed and a #185 High Speed set the mixture to two turns out and reassemble.
Fire the bike up and purrrs like a kitten straight off ... let it warm up for about 10 mins and take it for a ride ... WOW ... no coughing more power mid-high end totally different bike to ride ... I am sure I looked like the Cheshire Cat while riding ... was grinning from ear to ear!
Also ended up getting a windshield from a fellow forum member and that makes huge difference now it is getting cooler
... good thing about TX is we can ride nearly all year Have a Safe and Happy Thanksgiving
