message: Comment on the engine diagrams: the classic V-twin has a single crank pin shared by both cylinders, not dual crank pins as drawn.Rracecarr 00:53, 11 May 2006 (UTC)

replies: text: Sounds like you are trying to favor one brand over another.  Are you talking about the V-Twin design from Daimler/Maybach (the original), The 1902 Clement, the 1930 Brough Superior, The Transverse V-Twins from Victoria, Moto Guzzi, Honda, or others?  Many archaic brands use a single crank pin.  A modern V-Twin might not.  This sounds like you are trying to promote a single type over another type largely because you know of few of the others.  V-twin crankshafts have both single and double crankthrows.  V-Twin engines vary quite a bit in V angle.  Some of the Honda V-Twins are also Turbo-Charged.  Are you favoring one brand over another... I think you are. The solution is not to restrict the discussion to one type, but to include all types if you want to claim to be encyclopedic. Krontach (talk) 07:23, 26 May 2011 (UTC)
thread_title: Incorrect Engine diagrams

message: On the workpage I have reformatted this article with conventional section formatting instead of a table in the cylinders and configuration section.  I'm not sure which one is better.  Probably it's better to keep it simple, for long-term maintenance. --Dbratland (talk) 23:52, 10 December 2009 (UTC)
thread_title:  Workpage shows formatting without table 

message: If you are going to include steam veolcipedes then there should be an infobox for these types of engines.  This should include:
*Manufacturer
*Date of Manufacture
*Type of Fuel (whether wood, oil, charcoal, coal)
*Fuel Capacity
*Type of Boiler
*Operating pressure
*Engine types (whether piston, turbine, rotary, Lear) etc.
*Number of cylinders
*Valve type (sliding box, rotary, poppet, sleeve) etc.
*Start up time (typically 20 minutes to an hour)
*Water Injection type
*Water capacity
*Operating Range
*Brake Type (whether shoe, air brake, hand actuation)
*Brake Actuation (manual, automatic)
And this should also be consistent with the terms used to rank Steam Locomotive engines.  There are very good reasons why steam doesn't exist as a viable drive type for transport machines.  One is a lack of safety.  Another is lack of range.  There isn't going to be a relevant AMOUNT of information on these anecdotal machines for many of these relevant steam description categories to be answered.  I submit that steam should NOT be included as it lead NO WHERE and such machines are singular.  If you can show me a successful steam motorcycle manufacturer then by all means include it.  If you can't I suggest you stop increasing the noise level with unimportant trivia such as anecdotal steam velocipede acknowledgement. Krontach (talk) 07:06, 26 May 2011 (UTC)
replies: text: Steam engines are included for the simple reason that the majority of reliable sources include them when reviewing the early history of motorcycles. We aren't making up our own concepts here, we're going where our sources lead us. The reasons for going where our sources lead us are found in Wikipedia:Five pillars, Wikipedia:Neutral point of view, Wikipedia:Verifiability, and Wikipedia:No original research.<P>If you have a reliable source you can cite who states that they do not think steam motorcycles count as motorcycles, then you should add a citation of their opinion. The only one I know of is Cycle World's Kevin Cameron, and I've repeatedly cited his opinion on Roper steam velocipede, Michaux-Perreaux steam velocipede and Daimler Reitwagen. I don't think we need to belabor that point further. It's a minority view and WP:UNDUE places limits on how much attention you give to minority views. --Dennis Bratland (talk) 16:04, 26 May 2011 (UTC)

message: Is it time to include this class of engines or are we going to be technical and exclude electric because they are motors?  — Preceding unsigned comment added by Kellnerp (talk • contribs) 00:58, 3 February 2012 (UTC)
replies: text: They're not excluded. There's a section on electric engines, tagged for expansion. Expand away. --Dennis Bratland (talk) 02:08, 3 February 2012 (UTC)

message: This article was originally created in 2005 by a US English writer, User:Bruce2, and the article kept US English until specialised was introduced in January 2010. Since then it has had a mix of US and UK spelling. MOS:RETAIN says in these cases, we "use the variety found in the first post-stub revision that introduced an identifiable variety." So I'm adding  and changing all the spelling back to US. --Dennis Bratland (talk) 05:25, 29 July 2016 (UTC)
