[Engine identification]

I’ve had a look and the engine number is different to the one on the v5, the engine fitted is

N705-122796
 

Is anyone able to confirm the age and model of the engine with this number? 
 

thanks

Evening all, 

ive just acquired a 1999 gsx600f. I gave it a full service yesterday but found that it appears to have a different engine in. 
 

according to my data it should use cr9ek spark plugs but the ones I removed where dr8es, obviously these are a different thread size. 
 

am I right in thinking this would make it an engine from a 1988-‘97 teapot?
 

is there an easy way to tell without stripping the fairings to look at engine numbers?
