I think every quad has its purpose.I have a Friend that rode a banshee for 3 years it was a 1995. I had a 300ex then i bought a 400ex and we ride mostly woods any way, we traded machines for 20 min. He sold his the next week. It was a awesome machine but not for woods.Just like the 400ex might not be the greatest in the dunes. He ended up buying a 250x and we put a 350x motor in it.

 

I also have a 250x could you tell me a little about the 350x conversion??

 

I got everything from powroll. If you search the web for powroll they have a web site. It is a easy coversion.If you have the tools and a little mechanical skill.
