Stock 9T driver dimension

[Batwolf]

I poked around in other posts yielded by a search and called a few parts suppliers, but for the life of me I cannot find dimensions for stock 9T drivers on my '03 Viper. The nearest thing I could find was on a mountain sled forum and it said the diameter is 7.219" for most Yamahas falling in the same category as mine. Is this an accurate measurement for a new OE 9T driver? Admittedly, I had my drive axle out during Christmas and totally flaked on taking some measurements..

Dude, you're the man!
Thank you!

I hadn't given so much as a thought to referencing and 4 stroke resources..

Or you can simply do the math . . .

pitch * teeth / pi (3.1416)

2.52 * 9 / 3.1416 = 7.21925133 . . .

Guess I didn't have the witts about me to look up the conversion...

Thanks...
