Currently restoring a D1 bantam.I took a chance at an autojumble and bought what I believed to be the correct silencer , but it now transpires that it is probably off a D7? as it measures 32".As I only paid peanuts for it ( and will probably sell it on again if not suitable)I'm not too bothered.However, in the meantime I need to know if my 125 will start/run with this exhaust ( once the engine is eventually completed)THIS IS THE FIRST TWO STROKE i'VE OWNED AND SEEM TO RECALL THAT EXHAUST LENGTH / BORE ETC IS CRUCIAL.
MANY THANKS FOR ANY ADVICE.
