I replied last night but it did not post.
Yes I have run these pipes on a 1983 SRV engine with Boysen reeds and twin stock 44mm Kehin butterfly carbs in a 1981 SS440 chassie for drag racing. No bottom end at 3400 rpm but with 5000 rpm engagement it was a rocket in 660ft runs. These pipes make power at about 8500 rpm so I used a Comet 208306A primary from a 1981 SRX. If I recall, this particular clutch is a little larger diameter than the stock primary which pushed the stock Yamaha secondary to its absolute max. I used uni-filters because with twin carbs the mag side had limited room with the SS/SRV's gas tank extension. I had to play around a lot with the pilot jets in the carbs to get it to rev off of idle but once the main jets took over there was lots of power. With this set up the 535 fan never stopped pulling in 660 ft.
The SRV stock was a 7000 rpm engine and although I never had any engine problems in the drags I doubt it would hold together for a lake run. I only ran into three minor problems at various times with this set up for drag racing including a cooling fan exploding, a secondary clutch spring failing and a new belt snapping in two. I still have the engine and have never had to tear it down but most other Yamaha 535's I have worked on over the years had signs of significant bearing chatter when I split the in the crank case halves. This was at 7000 rpm so running this engine at 8500 rpm to make useful power with the VMax pipes for any length of time is likely pushing your luck.
Based on my experience I would suggest that running the VMax pipes on an SRV engine for anything other than modified class drags would prove to be disappointing.
At one time I started to switch over the twin carbs to the smaller 38mm Kehin's from the 1980 SS440 to try and improve the bottom end but I never finished the project. Running smaller twin carbs might get you down into the 4000 rpm range for engagement which may be still a bit harsh for non-racing applications. I stayed with Kehin's rather than moving to Mikuni's so I did not have to change the throttle lever and was able to easily adapt a standard dual throttle cable to the stock carbs. Because of he high engagement RPM for drag racing the lack of low end tuning on the Kehin's was never an issue.
I had a hoot building and racing this sled back in the day so I hope some of this is useful.
