The Vmax has the steep fork angle that a road race/Ninja type bike has and if the front tire is not in great shape and balanced along with the head bearings not set correctly you will always get the death wobble at high speed. We have been building supercharger systems for the Max since I got my first one #113. We have built a lot of complete Magnacharged Max's and we always rake the front end back by adding more rake the frame and a smaller front tire as the supercharged shaft drive bike with our overdrive fifth gear will go past 200 mph and a wobble at high speed is beyond your heart leaping out of your mouth. The Vmax will always decrease the rake when in deceleration from the drive shaft lifting the back of the bike thus making the the fork angle even steeper and causing a speed wobble more likely. We have been 240+mph on a Max with a Turbo going thru a freon spray inner cooler into the Hilborn hat on the Magnacharger with port injectors a and NO2 and the frame was charged with Halon for 6 seconds of fire suppression in case of explosion and that bike had our over drive fourth and fifth gears in 1988!
