I'll throw a picture up tomorrow, ,
the Evo 125 I race at the moment probably fits the bill,
It was left in my garage by son who move out as a 1978 IT 175 frame with a '74 TY175 motor in ti bent forks that would not move
etc,
It now has IT 175 frame, DT175 gearbox with 1981 IT 125 barrel and head, YZ piston , dt175 exhaust cut open debaffled,
and modified to come up the left hand side of the engine, home made stinger and silencer,
DT rear wheel and brakes, TS185 front wheel and brakes, YZ125 E forks, XT250 rear shock,don't know what the carby is off, tyres came from a wreck at the tip, side covers from some sheets of plastic fround on throw out pile.
Lots of this bike came from things Nathan discarded
cheers
