Hey guys, I recently bought a MT2 and im loving it so far but its only 2wd. How can I convert it over to 4wd? I have looked thru the manuals and cant find anything about it. Please help?

Also im looking to get some good upgrades like a bigger fuel tank/roll cage. If somone could give me a link to a good website that is relyable and is neat. I would aprecheate it.

-Thanks
