Engine/frame design question

[gokart_guy]

I am building a race car, welding the frame from scratch from 4130, like most of you guys. Does anyone here know where I can get some mounting point dimensions for a 2003 Yamaha R1 engine for modeling the frame before building it? Or do I have to use trial and error to figure out the correct mounting dimensions?

Thanks

I think there's a SW model somewhere in the forums.
