If you want to take the bus back to Malaysia, I suggest you cycle to JB larkin and take a bus from there. This will save you the hussle of loading and unloading your bike through the customs. In my humble opinion, cycling the bike through customs is easier than carrying it through. Hope this help.
Guys really appreciate suggestions above, will consider cycle back to Larkin as my 1st option .cos we got 6 paxs here..may easy for ur just hope in our local bus then claring the custom with our packing .
