I want to remove my blower next week and let it port from an engine builder here in Germany. He never port a L blower before, but after sending him some pics, he told me that it will be no problem. I believe him and hope he will do it right, but sending the blower to the USA and back is too expensive.

Please give me all the tips he/I need. I will remove the blower and send him it, are there any tricks I have to know removing the blower.
When I will reinstall, is there any fluid I have to add or refill???
What is about the blower, when he install/reinstall the rotors, any tips!!
Or some porting tips??? I've emailed stiege, but they can't say me anything, I understand this, it is their job, but some tips would have been fine. I think no one of you guys will send a blower to Germany. LOL.
