Calculations
There is a calculation of displacement on the page. I see two problems with it. Just state that a bore of 3+3/4 in and a stroke of 4 in gives a displacement of about 88 cubic inches (1450 cc). J IM ptalk·cont 07:05, 12 March 2012 (UTC)
 * 1) We start with measurements of bore & stroke of three significant figures (3.75 in & 4.00 in, 100th-of-a-inch i.e. ~quarter millimetre precision is dubious to start with) and we wind up with five sig figs (88.357 cu in precise to the nearest thousandth of a cubic inch or 16 microlitres). Are these mathematically perfect cylinders, no, they're motorbike cylinders. This is false precision.
 * 2) A volume-of-a-cylinder calculation seems unnecessary anyway.

Number of Valves
The number of valves is one of the most basic descriptions of any engine, but is not included in this article. Should be updated.

This page doesn't have a table for specifications
This engine is listed as a predecessor on https://en.m.wikipedia.org/wiki/Harley-Davidson_Milwaukee-Eight_engine But doesn't include a similar table with a predecessor or successor a long with various other facts. 2601:98A:A01:2F80:1D41:8827:4377:4678 (talk) 02:38, 16 February 2023 (UTC)

 * what year was the 88B released? 2600:1700:9B60:11E0:5C07:7C7F:A89E:F4A (talk) 06:12, 30 April 2024 (UTC)
 * The balanced one for softtails? I believe it was 2001. But I can't find a source on this. I know it didn't come out the same year as the TC88 though. War (talk) 06:43, 30 April 2024 (UTC)
