Hey guys found an OLD engine in the shed, its a honda 125 missing an assortment of pieces. i cant recall the year on it but it does have compression and the valve train is intact, But there isnt a carb, oil plug, CDI coil, or some covers for it. what do ya think?

Might be worth rounding up the missing pieces as long as the lower end and tranny are still good. Do you know the history of it? If not, do all the gears seem to work? As you turn the engine over (w/o spark plug), find some way to lock the sprocket down to keep it from turning and rotate the engine in each direction checking for any excessive freeplay or strange noises from the crank or tranny. (do this test in each gear)

Ive played with it before and it feels ok all round, but just needs a few covers. It isnt missing anything critical other than the carburetor from what i have read a mikuni may be my best bet. there are coils that i may use but i dont know thier state or operating voltages, im going to assume the engine is 12V but i may get shafted with the 6V gen coils i dont know yet.

We could probably research the serial #'s and confirm if it was 12 or 6 volt, or if it did (or can) use battery eliminator type componets...

I would say it might be worth it, but it depends on what u want to use it for.

Get the ORIGINAL carburetor setup for that engine. If you just throw a random mikuni on there your going to have lots of fun with jetting....
