250cc Project X

[greenhuman]

This is my latest Project X 250cc ATC70 engine. This is a combination of two seperate Chinese 200cc OHC engines. To get their 200cc's, one model has a big stroke and small bore while the other has a big bore and short stroke. I have combined both models as in long stroke bottom end and big bore top end. It had its first test run last night and was very successful. Big HP everywhere.
The next Project is a laid down 350X in a 70 frame.

wow, what motor is that

[Aka_am]

That is awesome! :naughty:

[blue27]

you guys have to much time on your hands!! lol


That is cool to see something different.

[Billy Golightly]

Awesome, just pure Awesome. You getting geared up to defend yourself against the 250R powered 70? :lol: You guys down there are just insane on that stuff.

[super90]

Thats a wiring nightmare to me! But that will be pretty sick ones it runs.

[greenhuman]

Once it runs? It does run! Like I said, I took it it for a test ride on Friday night. It feels like a minature 350X. Once it's run in, look out.

[super90]

Sorry I just saw that you tested it. Good work, i would never have been able to figure that out. Are you using the origional plastics and tank?

[mart]

nice greenhuman there werent any leaks i hope?

[SYKO]

was this a twin cylinder motor? ive never seen a chinese motor that lays down in the front, just woundering:wondering

edit: i'm talking about the plate on the top of the case.

[ATCR250R]

Thats where the cylinder use to be. Check under where its at now. Thats weld buildup that has been remachined so it will mount there:twisted:

[greenhuman]

No leaks Mart, best weld job to date!
These are Honda copies with late model specs like bearing cam, multi-plate cam chain , flywheel CDI pick-up, electric start and are super reliable.

I know this is a old thread but could you build one of these motors to go into a 200x? Also I'm talking about leaving it in its ORIGINAL form NOT modded into laydown style.

[200XMichigan]

That would just be a Lifan engine that will bolt into a 200X. No one would have to do anything other than order it off E-Bay. He used two engines to make a lay down 200. The engine that the upper end came from looks like the Lifan engine that goes right in a 200X.

[Shorty]

oooooohhh welll That was a very dumb question....LOL

[Vealmonkey]

He did not use 2 engines to make a laydown 200x. I have 2 sets of his cases.
