Yardster,
As long has the engine is built in America and or is a brand name you can't go wrong. I did a search in Google yesterday on Chinese built go carts/motorcycles and was shocked. You know the hottest thing going are these hopped up little Honda XR50's, we have better and $3500 in one and these knock off's with what looks like the same parts cost under $1500, guys ride them 2-3 hours at a track and are disappointed they fall apart. Ours keeps running and running with very little maintenance. I know this is sick, Ya get what ya pay for.
