    Having compared all of Partzilla's Z600 A microfiche & this sites ZL 400A Microfiche every part number seems the same, the only difference seems to be Bore & stroke size, 60mm x 52.4mm against 56mm x 40.4 mm the engine casting numbers are identical, the camshafts, valve gear, clutch, crankshaft, the wet liners...cooling system, Frame & fittings, obviously the side panel transfers differ. I have been told the ZL 400 has a different final drive ratio making things easier for the smaller output engine, but as yet I haven't found any parts to confirm this difference for definite!

    Crankshaft and liners can't be the same. If in error, they're listed to be the same then other part #s are probably wrong too.

    Edit: I think you're only seeing the part # prefix shown on the exploded view. Look at the list to see the whole part #.

    I've been more interested in why there's a difference in horsepower between the 600A and 600B. It seems the only different parts are mufflers, airbox snorkel and main jets. The A model uses 85-98 mains and the B uses 78-88. I didn't check, but I bet the 400 uses those same restrictive parts. Fortunately, I have the 600A but anyone with the B model can get the increased power of the A by changing those three parts :). Too bad it's more difficult to change the B model's cheap appearance :(.

    The 400 A definitely doesn't suffer from restricted carburation, it has the same 30mm CVK chokes as the 600, will check jets when I have time. I agree the Later "B" Models look like a much cheaper deal in parts n' styling!

    According to the Figures 600A 73.4 or so bhp & Z600B quotd as 60//61 bhp, a masisive difference no less. Having said that, I suppose restrictive carburation, air-box resonance n' restrictive Silencers may account for the difference. Maybe the 600 B has a more flexible engine lower down? Or is it just a cheaper product all round?

    Having said that have u seen the laughable boasted power outputs of some of the new machines, 2015 plus,,,, 250s, 350s, 400s, their outputs were beaten 35 years ago, before various restrictive practices came in, plus engine cylinder numbers are again reducing to singles n' twins! Progress eh!

    They the Political Class want to see the end of ordinary people having personal transport! Soft on Multi-National Corporation's n' their poisoning n' polluting deeds n' hard on the individual!
