Default used 114 engine for a 107 fatbob upgrade?

Somebody has upgraded his 114 fatbob to a 131 engine.
His old 114 engine has about 8000 kms.

Do you think is a good idea to upgrade my 107 to that 114 used engine?? I feel it is not, because of worn cam, bushings and tappets.

Any comments?

8000 kms is almost new. If you put a torque cam in the 114 you will notice a BIG gain, without the cam I would not bother.

Like Hulkss said, I would not bother to change just between the 107 and stock 114, not worth the effort or money. I have 2x107's and 1x 114 and the difference between them is not that much, I even find that the 107 have more spank in
the lower RPM then the 114.

I’d rather put my money towards a big bore 124>114.

Free? Yes, worth every penny.
Cheap? Maybe, if it's cheaper than a big bore kit, and you can do your own labor.
8000KM is nothing- I would ensure it has, or make plans to get, the latest oil pump (& maybe a decent cam) before going further.

That's like 2nd service milage. That's a pretty new engine.
