Welcome to the site, Yamadude0!:schild27::schild27::schild27:
There are a few of us around here, even when it's 100 degrees.:3devil-sm
You might try contacting the Yamaha Sled Talk blog. I believe the author helped develop the Vmax-4. He may have information for you, or know where to find it. At any rate, I'll bet he would be interested in hearing about the sled. http://snowmobiles.yamahablogs.ca/
You can email your pictures to 8BU or me and we'll post them.
Another bit of history, of the Yamaha inline 4 twin crank 750, cases are designed to be narrow for bike frame vs snowmo frame, but as you can see the basic layout is the Vmax 4 powerplant in the making, funny the consumer version- (had to have a racing license to buy one) called the TZ750 was rated at 140hp similar to the 92 v4 hp rating, hears a pic of bottom end with top part of case off. and some sounds from a u tube video http://www.youtube.com/watch?v=3aE-B4kL5rg
