And also, sorry for the long silence! I'm thrilled to see so many helps from all you awesome people! But I was busy during the weekday, and finally it is saturdya here in Singapore today, and I got the chance to continue the work.
Just went to get a spark plug tool, as it is required step as described in BDub's youtube tutorial, and while i'm at it I also went to get the gasket kits, though I'm short of the cylinder bottom 0-ring, they ran out of stock, Fred do you have any recommendation where I can get it from the states or maybe Japan?
They also have new cylinder going for SG$380, but I didn't buy it yet, am thinking about the possibilities to upgrade to TW225, is it possible on my 2010 engine?
Start working yesterday evening after work.
