Hey guys

Already thanks for the great feedback, I knew this was the right place to post this question

And with some adaptation according to your feedback, I think I can stay longer and longer on the bike And it slowly looks like I could make the trip starting here in Europe and drive down there

Regarding some of your topics:
Bike:
KM per day dropped to 200 km on 6 out of 7 days, so around 180km on avg. And also dropped the Ferry/Highway and Service/Parts (which would actually include new tires) to a probably more reasonable amount.
The "Ferry/Highway" part would also include the price for a guide around China where I found some reealy scary costs.. But I'm still trying to figure out how much it will really cost.

Food/Entertainment also dropped a lot, but not sure how much it will cost when starting here from Europe, I guess the avg will come down a bit, but I don't want to go all the way down. I assume just one.. I don't know.. Whale watching trip or a good meal in a bigger city or something would increase the avg again.

Regarding the hotel prices, I'm really not sure what happend there. I checked out some hotels in India regarding prices, and back then (last year ) I found prices around 100 USD as well. Well, I guess it wasn't the best idea to check for prices at Agonda Beach during christmas / new year time.. Now those prices dropped to around 30-50 USD as well. So I think it's safe to assume the avg. cost will not be that high.

Which would leave me with something like 200 USD including my "home-based" costs, withouth it around 140 USD, which would bring me to around the same standard as tmotten. But still somewaht over-estimated (at least for Thailand) to have some security in it:
