1974 Tm250

Not a mod i have seen. definitely not a Suzuki or Beamish mod

Not on your engine. its was always the worm drive as on the TS250. in the newer black engine bikes the clutch arm was moved to the right-side of the engine . works in the same way as the older TM mx bikes. You can upgrade the TS based engine like your. to a Clutch case of the TM250. rare to find these days. but they do turn up. It then will look like the picture ive added to this post

The 250 motor in your bike , is a modded Ts250 engine. in the Beamish world, there called the silver engine. the 325cc engine is a new engine and only came from Suzuki as a 325. Beamish in the UK got some engines converted down the 250cc(because the 325 can be a bit of a handful) these engines are called the Black engine bikes. Also an interesting note, Suzuki never used the engine themselves, it was a UK Beamish Suzuki exclusive.

Beamish never built the motors. Suzuki did them all. On the later black engine Beamish , Beamish had some work done on the top end to convert the 325 to 250.
