clutch and gearing changes?

[yammi4ever]

Ordered an m10 151 for my Attak, and was wondering if anyone thinks I will need to change anything other than what yamaha says to go west 8 to 10000 feet. I am putting 8 tooth extros, and plan to take the rivits out and gear down on the top gear like they tell me on a normal Attak. Will I need to do anything else, or will this be enough?

thanks for any input

What is an Attak? I really don't know!
