Talk:GY6 engine

October 2006
I keep seeing this stuff about the GY6 being a clone of the Honda 125cc Elite engine. I have a Honda 125cc Elite and a Chinese 150cc GY6. Both engines are 4 cycle internal combustion single cylinder engines. That is where the similarity ends. Among other things the REAL honda engine is water cooled, has external valve adjustments and NO cooling fins. THe Honda cyclinder leans about 15 degrees to the rear. The GY6 might be 15 degees off horizontal. The GY6 may be a honda clone, but it sure as heck not a clone of the elite/spacey 125cc scooter engine.

Somebody needs to check their facts. 21:14, October 15, 2006 —Preceding unsigned comment added by 68.215.40.190 (talk • contribs)

This is a picture of a 1985 Honda Spacy/Elite 125cc engine (the 150cc version is visually identical):

These are two completely different engines. I just hope no-one reads this article and buys a GY6 to put in their Honda Spacy... —Preceding unsigned comment added by 91.125.146.80 (talk) 23:02, 28 November 2009 (UTC)

Proof of Honda's design input?
As far as I can tell, the GY6 engine was never used in any Honda product. It seems to have appeared in the 1990s in Chinese and Taiwanese models. Whether or not the engine was actually designed by Honda is anybody's guess - I have yet to find conclusive evidence which confirms or denies Honda's involvement in the design of this engine. There doesn't seem to be a reliable source of information on these scooter engines, and this article is not helping to cut through the confusion - users have pasted excerpts from this entry all over the internet, further exacerbating the problem. —Preceding unsigned comment added by Colindoyle (talk • contribs) 22:27, 9 September 2008 (UTC)

Most of the "references" just go to sites selling GY6 parts. —Preceding unsigned comment added by 70.112.230.6 (talk) 03:52, 13 March 2009 (UTC)

The GY6 WAS used in the Honda Spacey and Elite models in the 80s! —Preceding unsigned comment added by Steveatgy6 (talk • contribs) 00:47, 1 October 2009 (UTC)

Incorrect. While the Honda CH80 (found in Elite 80s) specs were similar to what is rumored to be the original GY6, there is a major difference: engine orientation. The GY6 design is very specific: it is a horizontal single cylinder forced air cooled overhead cam engine with built in CVT. The Honda CH80 orientation is vertical. -Mo 70.16.221.184 (talk) 18:20, 30 January 2012 (UTC)

Links to possible references
A recently developed resource that covers most aspects of GY6 maintenance and tuning is "The GY6 Place" a colorful site that caters mainly for the amateur GY6 owner.

These links have been added because they are genuine referential links, they are not commercial sites and at least one (The GY6 Place) is purely a reference only portal —Preceding unsigned comment added by Steveatgy6 (talk • contribs)


 * Your motives aren't the issue. That's great that you're not trying to benefit commercially, but it doesn't make any difference.  The links fall under links normally to be avoided, such as community forums, and retail sales sites.  What this article really needs are independent, reliable sources.  Just to be clear, it is not Wikipedia's job to be a directory of useful links on every topic.  Whether these links are helpful to someone buying parts for engines is not relevant. What matters is whether or not they make the article better according to Wikipedia's criteria.  The Open Directory Project might be a better place to submit useful links, at http://www.dmoz.org .  Unlike Wikipedia, DMOZ.org is a directory.--Dbratland (talk) 01:09, 1 October 2009 (UTC)

Ok, if that's te case then why have you left links for two forums (one of which sell parts on the side) in the text, but have been so very strict in removing mine? —Preceding unsigned comment added by 78.86.221.123 (talk) 11:14, 1 October 2009 (UTC)
 * By all means, delete them too. I'm not responsible for every leaf that falls on Wikipeidia. --Dbratland (talk) 15:46, 1 October 2009 (UTC)

Regarding Cleaning of Article
Due to the article not meeting Wikipedia's standards and not having citations, I have edited the page to incorporate only the non-contested content contained previously in the article. Due to the nature of the lack of evidence on the topic, the article needed a major cleaning.

I would welcome any verifiable additions to the specifics of the GY6 engine. Especially in regards to its history and origins.

I've tried to clean this article up a bit, reorganized it some, and rewrote a couple sections. While most of what I've added is relatively basic and common knowledge, it could still use some citations. I've just about run dry for edits here, though. Please add any verifying links you can think of, regarding the basic construction and layout of these little engines.

Wow, this article really was pared down.

I'm Mo from Scrappydogscooters. It is my job to be an authority on these engines and parts.

Actually, not all of that information that is "common knowledge" is correct, especially with respect to Taiwanese manufacturers Kymco and PGO. They are know to not use the GY6 standards to the letter. Kymco is known to change small things here and there (such as exhaust port angle or ignition) to make sure their parts are proprietary. I can't speak officially as to their motivation, I'm guessing it has to do with assuring any parts you change out will have to be "Kymco Quality." For service manual purposes, the Kymco Super 8 is a GY6, but when it come time to order parts, order Kymco. PGO is known to use a connecting rod with a smaller wristpin than the GY6 Standard. I don't know if and what other differences may exist.

There are two other well known anomalies in Chinese GY6 manufacturing. First are engines made by Qianjiang (code: QJ) are known to use JOG 2-stroke transmission parts, at least in the CVT. The other is the specific "-3" engine made by BenNeng (code: BN), also referred to as a GY6-B engine. These engines have a taller head, unique crankshaft, and an extra long swingarm to accommodate a 16" rim.

I have to agree that there is no known use of the GY6 engine in an actual Honda product. I know that Honda does (or has) contract Jialing (code JL) for some of their engines (code JH), and they do make GY6 engines themselves. That's about the only link that I am aware of between Honda and GY6, which is circumstantial at best. 71.161.116.139 (talk) 02:59, 20 December 2011 (UTC)
 * If you look at WP:Five pillars, Wikipedia is an encyclopedia and What Wikipedia is not, it might help explain why most of the GY6 stuff doesn't belong on Wikipedia. If you ask me, there are more than enough websites -- forums, clubs, and commercial sites -- that tell you all you need to know about the GY6. But if you feel that even with all that, there is still an unmet need for some kind of Wiki article with GY6 lore, I would look to Wikibooks for a format that is more open to the kind of how-to advice that is the mainstay of the GY6.If you have reliable sources you can cite, then feel free to expand this article, but remember to stay away from how-to advice. --Dennis Bratland (talk) 04:57, 20 December 2011 (UTC)
