2 stroke cylinder porting for snow biking

[cr250r77]

Hello
A question for you 250cc - 300cc 2 stroke snow bike riders who have a juiced up engine.
What porting is ideal for snow bike riding?
A linear power curve with low end, mid range and top end power ?
Or a big hit at the mid range & top end ?

What have you guys done ?
Please let me know

Mid-top usually. Meaning everything after the pv opens. Below that won't get you anywhere very fast but might make it easier to ride if you don't have the skilz.

Mid to top as linear as possible… you want a nice long curve. Don’t go for maximum power over a longer power curve that was my first mistake when I started.
