Visually i can see nothing wrong, no scoring, no signs of burnt oil around the rings - a point that i forgot to mention though was the oil that i drained from the bike. if it was oil then im a succesful reggae artist... It smelled strongly of petrol and had the same viscosity of petrol, not thick like oil should be. Now my immediate thought was "how has this got into the system???" Ive seen plenty of cases of oil entering the combustion chamber but not petrol entering the oil system - any clues there??? i would hazard a guess that this has been in there for a while so probably caused excessive wear on some of the components... surely nobody is stupid enough to put fuel in the crankcase??? The previous owner reckoned that the bike had a full nut and bolt restoration a few years back, if so he sold me a different bike...

well i had a crack today - but it didnt go well... the ebay unit is a 2-HW engine whereas mine is a 3-KM (i believe) i removed the alternator but the mounts are totally different on the 2HW so no joy... I checked the markings on the ebay engine and it is a 600cc unit... I then went to plan B - and started stripping my old engine down - i had hoped to have it back up and running by tuesday but we shall see... so far its sat on a workmate with the head and cylinder block off (no sign of damage) no free play in the big-ends or main bearings - i might replace the rings while theyre out... now onto the clutch and finally the gearbox for signs of failure... its gonna be a long weekend...

Where would the stamp be exactly? just generally on the engine? ill be annoyed if its a 550... Theoretically could i strip the alternator off the old FZ engine and replace the twin units on the new engine??? then the plugs would match up - im not meaning to sound stupid but would my old FZ engine just be the same block etc with a revised alternator etc - or was the whole lot revised making older parts incompatible???

Hi guys my FZ engine has packed up and ive picked up another aircooled four supposedly from an FZ yesterday... Well typically its the same unit but after i fitted it to the frame it became clear that the electrical connections are different. the engine is an earlier model with different alternator etc (probably from the YX600 or something) im looking for help as to how i could make this work in my FZ - what needs to be chopped and changed so it will work - has anyone done this before??? any help is appreciated! nath

£500 ebay purchase as my first bike to replace my kwak AR125, ironically of the same manufacture year...

As above really... I started the bike this morning - normal cold start sequence: open choke, started fine - rode off and switched to second gear... The engine cuts out... It then wouldnt start up or even crank over - all i got was an oil light when you push the start button... i tried the usual of putting into neutral and other combinations but nothing... It took 15 minutes then it started without hitch... WTF???

thanks for the welcome guys! looking forward to driving in the snow - its gonna be used for commuting to uni everyday, replacing my kwak AR125 which is in pieces being rebuilt at the minute... so far its a nice bike! although a bit rattly on idle...
