V-max 540 Hp Question

From this site, which is incredible!, member ramblnman gave me these figures on the exciter--- 87-90 77HP @ 7250 rpm, 91-93 77HP @ 7500 rpm, and 93 exciter sx 93HP @ 7750 rpm. I was just curious how close the two motors were for HP in stock form (brother-in-law picked up a 89 exciter to rebuild)
 
The Vmax was built for the higher performance/Lake racer crowd with it's twin pipe/carb setup. Yamaha marketed the Exciter as a lower Hp., higher torque, turn to turn Trail sled. Within a couple of years the Magazines had quit praising the Exciter and complained bitterly about Yamaha not haveing a top end lake racer and hence the Vmax4 was developed !
 
AND THE VMAX 540 HAD PORTING UPDATE RIGHT FROM YAMAHA THAT ADDED ANOTHER 8 HORSE. REALLY WOKE THEM UP. THE EXCITER TO HAVE IS THE 93 SX. 3:16 (yammie tony)
 
I was given PDF copies of the dynotech articles for
1) '86 vmax540 updated porting
2) '86 vmax540 Bender FIII porting
3) '87 vmax540 pipeshoot out
shoot me a PM with your email address and I can pass them along
