Maybe I wasn't paying attention or maybe time has blurred my memory but I seem to remember Andy doing most of his 250 class winning on a TM powered TM. I'm not doubting that Andy owned and raced this RH engined bike but it's a newie on me.

 Stumpy? Walter? am I right or wrong?

Yes it should have RH250-10402 ..but it does look like an RH engine and the numbers are right.
By those numbers it's a '75 motor but no difference to '74.

Yes Firko i only saw him on TM engined TM's but that was a long time ago, maybe this bike was near the end of his vintage racing days.

Firko
Maybe you could buy this and mount the engine in a Maico frame? That would be a cool pre 75 racer.

Jeeezus Slakey...I've done some dumb engine swaps over the years, who could forget the XL Honda powered Montesa King Scorpion that I sold you? but that one would top 'em all. There's only one place an RH engine should go .......in an RH frame (or maybe a Cheney Suzuki frame, to be a bit different and close to politically correct).

For what it's worth, the Suzuki motor probably won't fit....the offset exhaust would be blocked by the front downtube. It needs a single downtube frame....maybe a King Scorpion Monty ;D ;D

The last 2 pics show another TM250 that is a TM250 Alison. Don't know why those pics are included in the RH/TM listing :-\

Alison the RH250 part of the engine # will be sand cast in the case if it is an RH engine

Alison that 2nd last pic of the ID plate riveted to the case is a TM engine i believe as i can see the oil injection line, the engine number on an RH is cast into the case below the front sprocket.
Maybe ask Rosco for a close up pic of it?

As I have said in another post...I can remember being on the starting line at Ravo many years ago at a Nats ...along side was 211 and next to him was A.C..... they were having a discussion about the RH motor in the TM at the time........that same meeting is the cover shot on VMX 1 (tho not actually numbered 1)....so that was 1998 and the RH is in it then....
