Yamaha 1300 Tourer - Yamaha 1300 Tourer Fansite

I have never strapped down a bike. I know I need to place straps pulling it down and forward into the wheel chock, 2 straps at 45 degree angles pulling forward and down and 2 straps in the rear at 45 degree angles and down. I do not know how much to compress the suspension so that I will not damage it.
I know there is a wealth of knowledge on this list so can anyone help out here?

Thanks,
