I think what Newoldstock is saying is you'll get much more help with specific questions that haven't been answered in detail many times over. The folks here are more than helpful and have a frigging AMAZING wealth of knowledge, BUT don't have the interest to rehash each general post from a new member such as "Help me build the fastest/lightest/etc minibike"
Some get frustrated when a post APPEARS as if no legwork was done. That may not be the case for you, but sometimes that's how it comes off
I am fairly new to this game myself. That being said, after some research, and with a clear idea of what your specific Gail's are, you will likely be able to create a build for much less cost than a prefab "kit". A "drag" bike will be MUCH different than a neighborhood cruiser. In fact, what's good for one, may SUCK for another.
Spend a bit of time on the forum using Search function, and we are happy to help after
Cheers
