Busa/ZX12 CAD models + other stuff
Does anyone happen to have a CAD model of a busa cylinder head and barrels?
Also if you over rev a busa (or any of the other big bike engines for that matter) is it usually the bottom end or the valve train that lets go
first?
thanks

Thanks Wadders. Can the valves hitting pistons be cured by using stronger valve springs and titanium valves etc.
Thanks Mangogroove, thats useful for a representation but im reealy after a 3d cad model so I can add bits to it.
cheers

It depends in what circumstances, uprating the valve train as part of a tuning programme may allow you to up the rev limit, but i'm not sure why
you would want to go down that route with an already highly tuned high revving engine? peak power usually falls off at the top anyway.The busa is a
hugely strong engine
as a base for tuning, within its stock rev limit. In my case the engine failed because someone (not me btw) changed from 5th to 4th at the redline
instead of of 5th to 6th, you can't over rev in normal circumstances because of the rev limiter, but if the engine is under load at the time (as
in my case), AFAIK no amount of engine work will save it.
There's a good busa forum here which may help.

Thanks for the link but im looking for an actual 3d CAD model, not a drawing.
