If I go down the rebuild root I'd be looking at making a custom rear subframe with race style single seat and hump as I've never liked the rear end on the 400 and possible looking at changing the nose fairing to something a bit more modern. Spraying the frame matt black and bodywork would be white. Moto GP style exhaust and that's about it.
If I go down the street fighter root, well I'd want it to look something like this. (it's a zx9r)



If I knew it would come out looking something as nice as that I'd deffo go for it but I don't know how well the 400 would look streetfightered.
Anyway here are some pics of how I'm getting on with stripping her, will try and keep it updated.

Rough mock up with things I had lying about, just to get an idea.



Thoughts would be much appreciated.
