The "Greenhuman 200cc motor"

[kilabeez0]

wasn't he selling these awhile ago? i want to know the cost of one for an atc70. i've been looking at 88cc kits, or Lifan 125cc motors, but i'm curious to know of greenhuman's 200cc monster:twisted:

so is that just a 200x motor layed down? Looks cool as heck! Wish i had the confidence to attempt to build one of these horizontal motors.

Those cases are not just whacked apart and rewelded. He is very careful and machines the cases so he can change the location of the head and still have all the proper oil passages and then he makes a machined cover for where the head originally mounted. The engine he sold on ebay was an aftermarket copy of an electric start 200 engine. He also does work on the original 200x cases which means you will have the kickstart and no battery issues. He put alot of thought into the re-engineering of the engine to do this and still have it run reliably and also be able to run a stroker crank and big bore kit if you want. There is alot of other work but all the little things he does would take a long time to explain. The only cut and rewelded engine a person is putting an atc70 is a highly modified 250r. And again, it isn't just hacked apart. The amount of work that goes into either one of these engines is staggering. Please be kinder in your description of how someone does their work. I believe the man to pretty much to be an artist, in my opinion anyway and would like to have and can fully appreciate one of these 200x engines and the amount of work he puts into them. A real labor of love if you ask me.

Im really sorry if anyone took my "hack apart and reweld" comment the wrong way. It didn't mean to make it sound like i didn't have respect fro their work. I understand that there is a heck of alot of work put into these motors, which is why i said, "i wish i had the confidence" to do this, as i don't feel that i could successfully pull it off. I know something would get messed up and the top end would probably be toast in minutes. Ill try to pick my words wiser next time i make a quick comment.

Brown shorts is right! Would be a fun ride, but with my knees stuck up under my chin it might be a challenge.

[Vealmonkey]

I'll apologize for being harsh then, Sorry. Keep your eye open on ebay. I'm not sure if his electric start engine sold or not. All I know is I really want a set of those 200x modified engine cases. I have a suspension 70 that one of those engines would really be a total E-ticket ride. I know he has a business and is a busy man. Good luck with your 200 engine search. If I see one of his engines listed on the bay again, I would be happy to email you about it if you were interested.

Email him at john@jmcracing.com.au i saw a couple of those engines on the workshop floor just the other day so they may be available for sale.

[KASEY]

well now there are 200 cc kits out for the lifan motors!!!! so its getting easier to have a kickass atc 70

[kilabeez0]

i'm all set with a used chinese motor for $1000. i understand all the thought and "engineering" that went into designing it. now it's a production line and it's not even on honda motors, but generic one's that everyone can get there hands on.

[kilabeez0]

haha, kasey i bit your style on the color scheme of my 70 btw. i'm trying a different color copper, but i dont like it so i'm going to buy the same one:twisted:

[RedRider_AK]

That 200cc laydown motor is INSANE. I want one, as well as a decent suspensioned frame to stick it in.... :drool:

[Vealmonkey]

I know you can buy brand new suspension frames. A member on another website is now making them. And I guess greenhuman will be making more of those electric start laydown 200 engines. All you have to do now is open the wallet and dig deep.

[Yamada]

Do you have more info about these frame Vealmonkey.??
On which website?

[RedRider_AK]

Yeah, I'd like to know more info on these suspensioned 70 frames as well.

[Vealmonkey]

You would have to look at the glamis dunes .com website and look for the atc70 page. I believe it is listed under the golf carts and side by sides but it might just be under it's own heading now. They aren't cheap but try finding an original frame. I have 2 frames now and sold a third one. They don't pop up for sale very often. Be careful, you may get bitten by the 70 bug.

[blue27]

Once get suspension on a 70 you will never go back... lol (thanks Vealmonkey). I have an A+ suspension frame, they were produced back in the 80s for kids racing in the 70 class, and now somehow ended up being riding by us old big guys. lol Yeah go to Glamis there is a bunch on just 70s. They are tough to find and do not go cheap, but worth every penny, and it is addictive. I will post some pics of mine later still not far enough along to show it yet, many mods from stock.

[kilabeez0]

i guess i should post pics of my progress. everything is coming together nicely. all i have left to do is figure out what kind of motor/kit i want.:naughty: Lifan 125 or 88cc kit?

[Vealmonkey]

You can convert the lifan 125 or 138 to pull start and it's no big deal really and you will have all new stuff. The 88cc kit you will have a new top end on 20 year old parts. And the cost for the lifan is usually less than $300 to your door and sometimes alot less if you really shop around. They also make a 110 monster kit for the atc70 but most people have said it's just too much for that atc70 engine. It seems the biggest complaint with the lifans depends on which carb you get with the engine and that you sometimes have to get a different intake manifold so it will fit the stock atc70 frame. Not a factor on the suspension frames. I converted my lifan 125 to pull start. You just need to drill and tap a couple of holes into the lifan magneto rotor and find a side cover from a trx70 and your in. You will have to find a plug of your liking for where the shift indicator was. Some people use a rubber plug, some use a chrome plug and some weld them up. The trx70 sidecover has the timing hole for the timing mark and will look just like a factory install with the stock 70 frame and cover the chain just like the stock atc70 sidecover. I didn't want all the hassle and extra weight of a battery and all the extra wiring. Most people remvoe the lower frame skid plate and fabricate a battery box that goes up inside the frame on the atc70 if they use the electric start.

[kilabeez0]

where have you found a lifan 125 for under $300? i'm still leaning towards an 88 kit because it seems easier to install. i'm still kind of in the dark as to all the wiring problems people have had with them and carb issues.
