2011 Grizzly 700.
I'm new to the ATV stuff.

Is it better to do a big bore kit or just raise the compression and do a better camshaft for more hp and torque?
Or is it better to do all of it together?
I was taught there's no replacement for displacement!!!
Looking for the best and most reliable combination!
Don't want to create a time bomb!!

Max out the pulley ratio to increase the torque, lower r.p.m. torque is what these machine rely on most. I suggest leaving the top end alone for reliability.

Thanks Jim!
What's the best way to do what you suggested? I'm learning everything day with these machines!
The key for raising the ratio is listed in my signature, start with this video to understand how the c.v.t. system parts work together:

I suggest going slow and starting with the shim mod, torque can be magnified so you don't need to go into to the top end for most conditions, if you go into the top end plan on a stroked crank.....4 to 5 mm's along with many other changes.
