Hi, I know this has been asked already but is this safe to use on a motorbike?

Hi yes. I use it on my old Norton. Works wonders but don't use the whole bottle

Will this restore old petroleum in my boat fuel tank

Don't know about boat, but my husband said it was great in the car. Hope this helps a bit

Can I use both the 5 in 1 cleaner and injection cleaner in one full tank?

You could but I wouldn't. Both products have properties that help clean various parts from the Fuel Tank to the Combustion chamber. In fact the description of both products show 1-2 identical properties. Just use one and then the other after doing a the guide line of 3-4 thousand miles.
