new here, few questions

[350BANSHEE350]

well im new here im only 14. i just got a new 07 banshee (long live 2-stroke) and i have a few questions

ok so i ride at temperatures from 10-30 degree celcius weathers, and the altitude is from 456ft-2000ft, my question is well i have to rejet when i go from 456ft to 1700ft or 2000ft and temperatures from 10-30 degrees celcius (usaully close to 15-25 degrees celcius)?

im going to be very heavy on taking care of this machine because there gone now

and i want it to last as long as possible

for stock would it be better to use regular gas? premium gas? or octane booster?

is the frame made out of steel or aluminum?

i only usually ride 40-50 hours year (this is my first manual quad so it well be stock)

i wont be riding it easy but i wont be riding it that hard, i ride trail and gravel rode. but i was wonder how long it well be until i should rebuild the topend?

what would be the best jetting, and how many turns should the fuel screw be out, for say maybe 1200ft at 20 degrees celcius?

what is the best oil to use after the rings have sealed?

 

sorry for all the questions but i like to ride things that are set up perfect ::

 

thanks alot i really appreciat it
