Talk:V-twin engine

message: I rearranged the content and synched with the "V-Twin or L-Twin" section of the Ducati V-twin Motorcycle article to achieve consistency in definitions across articles. I tried to make only minor edits to the original text and used existing content from the other wiki article. This is a restructure not a rewrite.
ADDED: Generally, any two-cylinder motorcycle engine with its two cylinders at an equidistant opposite angles from the center rotation of the crankshaft is referred to as a V-twin. 
FROM: "V-Twin or L-Twin" section of the Ducati V-twin motorcycles topic. 
PURPOSE: Consistency in definitions across articles.
MOVED UP: Reference to Harley 45-deg engine toward the beginning of the topic. 
PURPOSE: Better organization  and clarity for readers. 
MOVED DOWN: Discussion of 90-degree L-twin engines. 
PURPOSE: Better organization  and clarity for readers. 
RETAINED: Two S&S engine references. They really should be deleted. There are a number of other engine-only manufacturers and none of them are listed here.
RETAINED: The entire article has a motorcycle bias. Where is the Briggs & Stratton Vanguard V-Twin Horizontal Engine? Kohler, Husqvarna, John Deer?
RETAINED: The 90-deg counterweight note seems odd in this topic but I retained it as I am attempting a restructure not a rewrite.
DELETED: Indian from the list. I searched on wiki, on the Indian website, and did a general web search and could not find the v-angle for the Power Plus 105 engine - the only engine currently manufactured by Indian. Is this reference to the defunct original Indian or the bankrupt Gilroy Indian? If so, it would be equally odd to include Excelsior-Henderson in this list. Why is this reference even here?  Certainly, the Victory division of Polaris is better know and has higher production volume than Indian which is a limited-production or "boutique" manufacturer.
PURPOSE:  References to defunct, boutique, or low-production manufacturers would be rather obscure for the average reader.

replies: text: The Zündapp KS 601 is listed in the chart as having a 170-degree v-twin engine.  AFAIK, that model has a horizontally-opposed 180-degree, or "boxer" engine. Bricology (talk) 22:14, 28 September 2014 (UTC)
replies: text: You might be right. The KS750 had the angle narrowed to 170°, but I don't know about the KS601.  I've changed it to KS750. Sincerely, SamBlob (talk) 23:51, 28 September 2014 (UTC)
thread_title:  V angles 

message: Thanks Jeff for the reference, but it actually confirms my suspicion. It is comparing flat twins to transverse mounted v-twins, not the longitudinal V-twin of which the flat twin is being described as the ""logical alternative". I would argue that most longitudinal V-twins run nearly as cool as their 180° opposed cousins. I'll look for a source. -AndrewDressel 04:49, 20 February 2007 (UTC)

thread_title:  Cooling 

message: The Complete Guide to Motorcycle Mechanics, a text book from the Motorcycle Mechanics Institute (1984, Prentice-Hall, Inc., ) does not make this distinction.  See page 61.  Also, parallel-twins don't share a crank pin, and yet they are not called "Parallel-2s."  Unless someone can come up with a good citation for this distinction, I think it should be struck. -- Pi3832 04:54, 3 March 2007 (UTC)
replies: text: I concur with this suggestion.  Cite it or strike it. Respectfully, SamBlob 12:09, 15 June 2007 (UTC)
replies: text: I edited this with "common misconception" wording which perhaps should be removed since it's not all that common, and it's a matter of either opinion or original research.  People who make the distinction seem to be the same ones who believe that "V-twin" is a Harley-Davidson trademark and/or invention. Real Deuce (talk) 00:46, 21 May 2008 (UTC)
replies: text: Aha! Figured it out.  The Boxer engine is often differentiated from a "180 degree V" engine using the crank pin layout.  Added an explanation of this.  The reasoning behind the differentiation is that some of the characteristics of the dual offset crank pin engines are not shared with the more common V design and are instead shared with the boxer engines.  However, differentiating using "twin" vs the number two completely fails to convey this.  I can't find a reference to any other verbal shorthand for differentiating between the two layouts though, so it appears that while it is a source of misunderstanding, it does have some usage history behind it.  —Preceding unsigned comment added by Real Deuce (talk • contribs) 08:23, 16 June 2008 (UTC)
replies: text: Nicely done. After going back and forth for a while, these things often boil down to "some people call it A, and others call it B". Wikipedia is the only venue I know for getting to the bottom of issues like this. -AndrewDressel (talk) 14:13, 16 June 2008 (UTC)
thread_title: True V-twin vs V-2

message: WP:NOTDIR states clearly that Wikipedia is not a directory, not a collection of long lists of information, yet in this edit that is exactly what is happening. By all means list engines which have articles on Wikipedia, but where neither then engine manufacturer nor the vehicle have an article there should be no place for such content. If the company and/or engine is notable then write the article first. --Biker Biker (talk) 15:20, 5 September 2010 (UTC)

thread_title:  Filling list up with non-notable content 

message: According to an article in http://www.mcnytt.se/hem/drysdale-godzilla-1840cc-vtwin-monster-mash-2118 , there seem to be severe mechanical limitations to traditional V2's, in regards to the revolutions per minute it allows. Tradiional cruisers (ie harley davidson's) are hence unable to make allot of RPM. "Metric cruisers" (mostly Japanese brands) have regular side-by-side bearings, and do not have this limitation. Drysdale appearantly solved this issue with the Godzilla V2, by using a system similar to 1930's Mercedes Benz racing cars.~He worked together with Tony Foale on this. 
Mention in article.

thread_title:  Drysdale Godzilla V2

message: Hi,
I put a "portion to be merged" tag at this top of the page as it seemed to be the closest tag to use for the job.
The intention here is to resolve a problem that has arisen relating to the three main groups of 'non-V' or 'non-flat' twins, i.e. transverse or parallel twins, inline or longitudinal twins, and tandem twins.  
At present all three are being shoehorned into a single article called "Straight-two engine", which I argue is a far more obscure and minor terminology for some engine configurations, and not used widely by manufacturers. The previously unreferenced topic was started by a non-native English speaker, sometime ago. The preponderance of references suggests this does not meet Wikipedia naming conventions, as per WP:NAME; Recognizability, Naturalness, Precision, Conciseness, Consistency, English language use etc.
No changes to V-twin engine are being suggested whatsoever.  Only a short introductory paragraph and, perhaps, image gallery relating to the configuration be included at Two-cylinder engine "master page" for all configurations.
Thank you. --Bridge Boy (talk) 18:49, 14 July 2012 (UTC)
replies: text: There being "no changes...being suggested whatsoever" to this article, I shall remove the "partial merge to" tag, which was mistakenly misused by the proposer. Sincerely, SamBlob (talk) 17:07, 15 July 2012 (UTC)

replies: text: You're probably looking for this: Diesel model V-2. Despite the model name, the Diesel model V-2 is actually a V12 engine. Not even the Russians would make a 38 litre V-twin engine. Sincerely, SamBlob (talk) 15:18, 13 April 2013 (UTC)
