A Few 150cc GY6 Questions

[jmusser218]

Hey everybody, this is my first post on this forum. I joined because I've just recently aquired a 150cc gy6 buggy and all of the useful information I've found on the gy6's so far has come from here. I have a few questions for everyone. First one is simple; I'm looking at this battery for my buggy: http://www.amazon.com/YTX12-BS-High-...rcycle+battery
Will this work okay?
My other question is what are the best upgrades I can do to my gy6? I think it will need to be rebuilt so my upgrade budget will only be about $200. Wicht would be the best upgrades for this amount of money? Any information you guys can provide me would be greatly appreciated. Thanks!
