Rake and trail are a thing people need to be aware of when building bikes and what their intended use is. We messed around with that some on my drag project (it's a roller finally). My friend that made the frame wasn't happy with how it first came out. It has yet to be ridden, so more changes may be made still. He has a custom bike that he built from scratch that he runs at Bonneville, so he has some idea as to what he's doing. He'll hopefully be getting a record this year.
On my CT200U we're probably going to be lowering the bike 2"-3". It only sees street use and that will help a lot with being able to launch it, which is almost impossible now. Also got to play around with some rear footpegs. We could do wheelie bars, but I don't really want them on this bike.
