How to contact Suzuki ( Japan ) for engine information? ?

A friend of mine who is studying electronical engineering at the local german university, is in need of some information from Suzuki ( Japan). He could not contact the representative for the information that he needs. In addition, e-mail address is not available on Suzuki's homepage. What would you suggest him to do?

I have attached his e-mail, perhaps it will explain better what he is looking for.

Thank you so much for your help,

Take care

his question goes:

we would like to adjust our current engine to your 2004 model (Suzuki GSX-R 600 (K4)). We have had difficulty measuring some parts for this model, and we cannot locate diagrams for these parts. Would it be possible to send us dimensions for them? Any information you share would be kept confidential and would only be used for the purposes of our team. Requested part dimensions are as follows:

Suzuki GSX-R 600 (K4):
- Connecting ROD length
- Valve diameter
- Piston TDC height
- Piston and Head area
- Number of nozzle holes + diameter
- Lift profile

We are using GT-Suite software to aid our construction of this engine.
