*DISCLAIMER* I know that these 2 options of motors (250R aircooled, and 200X) that have the cylinders clocked forward with the cases machined and welded are not 200x cylinders on 70 bottom ends. I offered the 200x and 250R laydown motors as an option to putting a larger than stock motor under an atc70. You could also buy a Lifan motor. I don't think without a lot of machine work and welding that you can put a 200x top end on a 70 bottom end. But I may be wrong. *DISCLAIMER*

You Have A Keen Eye For Details. Just Showing Them Another Option.

I think you guys are all wrong. It's a 250R aircooled top end on an unknown bottom end. Hence the 2 stroke pipe and rounded fin style. The video link even has it running, its definatley an R top end.

You should have clicked all of the links. There are 2 links for the air cooled 250R and 2 links for the 200x. Both are laydown motors made to fit under an atc 70. As Kasey pointed out the cylinders are clocked forward to make it a laydown motor. I don't think it is possible to mount a 200x cylinder on a 70 bottom end so I offered up the links as an option.

..... and one is made by mart and the other by greenhuman....

the 200x model is available for purchase if you've got the green last I heard...

There is such a beast as a 200x top end on an atc90 bottom end! Plus a variation or 2 on a similar theme. Also there is another set of laydown 200x cases available. Contact greenhuman. He just pm'ed me and said another set of laydown 200x cases are available.

Any more laydown R cases available? or just a little instruction? the site shows it done already not a build up.

There are or were pics of how the laydown 250r engine cases were done. You can't believe how much work it is! There seems to be less work for the 200x cases than the 250r cases. The 250r cases were actually cut apart and rewelded back together! Amazing stuff or amazing patience if you ask me. I've never seen 250r cases for sale, but I've bought 2 sets of the laydown 200x cases. The laydown 200x engine is longer than a 125 lifan engine though. Hence the new trike project.
