Dt250 in yz125 frame was created by Robdangereux
Hi all, what a great site. From here I've identified my frame(1979 yz125f) and engine (1978 dt175e). The engine is woefully underpowered and tired so this would be an expensive rebuild plus all the extra tuning parts. An acquaintance has located a dt250 1m1 engine. Does anyone have a clue whether these cases are the same size as the dt175e cases? If so, it might be a simple swap and probably the sort of power I'm looking for. Ps if I do this a dt175e engine will be for sale. Thanks and thanks for a fab site.

No chance sorry as a far bigger longer motor. Good plan though, I like plans like that. I ran an RD200 in a PE250 frame for a while, sounded good with twin chambers but wasn't that fast.

Forgot to say welcome from NZ. I raced a "79 YZ125F back in the day. Had it on Methanol & was a rocket.
