sukida sk50?

Hi mate, you could be 360 degrees out, does the manual say anything about setting the cam timing on the compression stroke??? the T mark is a reference to top dead centre (TDC) position, when lined up both valves should be closed if on the compression stroke, you will be able to move each rocker easily. I'm only guessing here mate but check first that this is the position you now set the camshaft dot/hole. Make sure you pull the camchain taut at the front, the rear will stay slack until tensioned. good luck.
