Meet Elle Foofoo
PFA
Elle Foofoo is my 1983 Honda XL250R. I've had her for two years and last weekend I broke her. I'm planning to rebuild the motor but in the meantime I was thinking about swapping in a temporary motor. Looking mainly at air-cooled 250 to 300cc motors. Does anybody know what Chinese motors might be a direct fit or have a link to some kind of compatibility chart? I don't mind making brackets but I want to avoid any frame modifications.

The 250 RFVC engine probably wont share any similar mounting points with the common china singles which will drop in to honda frames ranging from 125-200cc.
So to put it simply unless you can confirm the 2 main engine mounts share the same dimensions there's not a lot on offer I am aware of. Plenty of room in the frame but it might have to be modified to go chonda swap. |

Well its the 2 exhaust port 250cc...
The Xl185 and XR200 had the 163FML 165FML engine case stamping which is basically the platform all the current china clone singles adopted and developed. If you can measure the 2 main engine mounts at the back of the case near the drive sprocket and they conform to the XL185/XR200 standard then any Chonda should in theory fit with some added bracketry |

I chuckle every time I see those. What supervisor approved that exhaust design.

Yeah it's the old clamshell design. The good thing is that the bikes uses the motor as a stressed member so if the swingarm pivot is in the right place I think it wouldn't be too hard to make a new front and top mounts.

So many engine choices. Is there a preferred motor that I should look into?
With the single down tube a twin port or side port exhaust will work but not a centered single port.

from what little I've seen on you tube an xl500 engine fits in an xl 250 frame...bolt in.
Any other engine would appear to require some significant and perhaps irreversible frame modification... Can it be done? Sure. Would I personally do it? probably not. |
