I was thinking about 911 conversion I like the fact that it would make the bike more beefy mid range and keep it with the serial of the original bike
I wonder what is better 750 block + 1000 barrels/piston/rods + 750 head & 750 carbs
or 750 block + 1000 barrels/piston/rods + 1000 head & 1000 carbs but then I would need Exup right?
and welshbanjo do you mean CDI when your referring to magic box or is this something different?

If you do a 911 engine then you will get more midrange by using a 750 head. You will have to open out the crankcases to accept the 1000 barrels and you should get better performance by using 1000 genesis carbs over the 750, if you decide to use 1000exup carbs then you will need to modify the carb inlets to accept them. One of the things to consider is whether you will need the later model conrods as there is a 1.5mm difference in the rods between the FZ models. When I did my 911 I had to try a variety of clutches from 1000 genesis to OW01 to try and stop it from slipping but that was 20 years ago and clutches may be better nowadays. Wheaty

Well I took tell fzr engine out and all I have is the servo for the exup but no exup exaust I will put the 1000 engine for the season and do the engine build in the winter.
Do the conn rods come out of the 750 with the 1000 pistons attached?
How would I tell if it needed longer ones? My guess the piston would go too low for detonation?
Thanks.

Almez,Yas (magic box is) CDI , wheaty is the guy to speak and listen to, he knows more about it than me, sorry i cant help on the 911 conversion side of things, sounds not to difficult if you know the right guy to work on the crank cases etc mostly std parts are used, but if your at it maybe nice pair of cams, stg 1 or 2 , good luck whith your swapping,

I put the 1000 in today and I'm just wondering how this is going to all wire to the new cdi I just want the option to go back if I do 911. I' sure I will figure it out Just looking at the wiring diagram for the bikes it looks not to difficult wheaty I was wondering do you still use the fz750 radiator (saw your posts) with the 1000 because this is what I plan to do.

Just read about this engine having oil coolers? Didn't notice one on the engine but he had it running infront of me before I bought it and I drained the oil so it should have leaked if it was open? Do I need one?
NM some of the engines didn't have them.

I presently have a 1000 Genesis engine in my bike and have not used an oil cooler, as I haven't used an exup engine I cannot comment on whether one is needed if that's where you're going. With regard to my earlier comment about the conrods, the early model FZ had shorter rods than the later model and the longer rods are required in a 911 engine.

the sump pan usually has the inlet and outlet for the oil hoses, it shouldnt be to difficult to mock up a pair of brackets to mount below the rad the oil cooler isnt that huge, if you look at Steve Parish UK works FZ750 he ran an oil cooler on the 750 , i think he used the 1000 sump pan, if any one knows better i stand corrected,

the giva away on his 750 was the Harris exhaust pipe was lower than most after market ones to clear the sump pan,

I have the inlet and outlet and they are blocked from what I searched my cooler is internal , and my old pipe wont clear the bottom so I have to use the 1000 pipe that came with it so its lower like you mentioned welshbanjo. My big problem is finding a wiring diagram that match the wire colors on this harness.. I have no idea what age the bike is only that its 90 - 93 despite the guy saying 98 SO I think I will have to pull the wire harness off the fz and switch to the chopped and spliced (not too bad) 1000. I'm not discouraged yet lol.

I ended up just switching the harness not too hard seemed easier but I had everything with the other bike and I'm just using it all even the speedo.
I am stuck at a point where I think I'll have to dent in the tank to seat it properly because of a valve on the engine for the thermostat I think.. grr

Road it today! 1000 engine seems more beefy and is pretty damn quick compared to before which is a plus best 500$ spent!

Hi almez
your fz750 is flooding because the o rings that hold the float metering valve into the carb body are perished and letting fuel to leak into the float chamber replace the o rings that hold the metering valve with viton o rings and all your problems will go have fun Andy
