Have other engines will fit a 94 YZ 125?

I might be trading some ATC 250r parts for a YZ that needs an engine and want to know what other parts will fit it

Current ride: 1986 TRX250R with lots of mods.

Have owned: 1981 ATC250R with lots of mods, 1983 200X, 1986 250SX, 1991 KDX200

If it is a true '94 it should have the first year of new motor design and many of the parts where '94 thru' 04 for most of the bottom end. Some differences in carbs used ignition / wiring harness and some differences in cylinders and pipes used. Newer 96 + pipes will not just bolt up to a '94

Sweet that is what I wanted to know. Thanks

Why does it "need a new engine"? Catastrophic failure with case and cylinder damage?

No engine at all. It's a roller with out wheels. He offered me a KLR 250 that needs a cam and has XL250 tanks. It much more complete
