zr7 motor in KZ750

Do the oil pans interchange? I could use another pan but GPz pans are hard to find. Not to mention an easy way to upgrade to a cooler if needed.

Not really the turbos have a sump pan for the scavenger pump .

I might have a na pan . Have to look in my spares .

the zr7 pump i mounted in the past was in my gpz 750/810 road racer. with 90 rwhp temps can get really high in racing, you're constantly on full throttle/high revs for 25 mins and oil gets scaringly thin when really hot, the extra flow i see as cheap insurance. a tuner friend runs every now and then an oil pressure gauge and by mid race oil pressure drops quite a bit. would do this change in a street bike only if i lived in very hot weather, carry high loads, etc. never thought that my kz750E REALLY needed the bigger pump in northern italy weather.

the zr-7 pan is really like the gpz's, if anyone is thinking of a bolt on way to have a cooler.

I don't have a turbo just a 82 dual track. I was wondering if the ZR will fit. My plug is stripped out and I have to wrap it with Teflon on a double oversized plug to keep it from dripping. I can make a steel sleeve to repair it but I'd like to have a spare just in case and so I can take my time without having the bike down.

I thought I found one on eBay but once I got it the oil cooler fittings we just blanked out and not drilled. It was black but it must haves been for a L, P or 700.

The seller was cool about it, he refunded my money and told me not to worry about sending it back.

Well then, that opens up my options.

I think the ZR7 oil pan is basically same as the GPz and later model 750 w/oil cooler pans. I put one on my 750E2 and it's a straight bolt on.

***The zr-7 oil pan does not have the hole for the oil level switch that the gpz's normally have. The spot for the hole is there but it is not milled out.***

That's why I chose to use the zr-7 pan and not the gpz pan, as I would have had to make a block off plate for the oil level switch hole that the kz750e's do not have.

IDK what happened there

Not an issue....

No kidding! :laugh:

Whre's the ZR switch mount? Would it be better to use one of those if using a ZR pump and relief valve?

interesting, my european z750 (that's how KZs were called here in italy) didnt have the switch... my two gpz 550 / 750 did...

ripped off the whole internal thing and used the switch external plate as a blank off
