Thanks for the advice,

I will think about it again, because it will take alot of modification on it, i afraid if the modification will become worst...

Now i got a new problem, when i start my engine with a starter box, certain time, all of the gearing part at the engine will come out from the place, when it happend, i'll have to fix it and need to take out the engine... that make me sick... every time that thing happend, i will check either the gearing or the mounting part loose... there is no loosing part in there... what should i do?
