General questions about an 86 350 fourtrax

I am a first time atv owner, I'm also a jeep owner. that being said. I am really happy with the power on my atv, but the turning is worse than my jeeps! is this normal, do they have someting that can help this, or do I have a problem that needs fixen? thanks a lot.

One last question, how many times can i make the double jump in my back yard before I break something? I'll let you know when it happens!

the bike is all original, even tires!
