thank for all response, i have taste some sample from it, it taste very dry and all yeast already setter down at bottom. by this time can i do raking or should i wait for few more week?i still wonder where the sour taste come from, is that possible it come from honey itself?
The "dry" is just that your recipe didn't include enough honey for there to be some residual sweetness in it after the ferment had finished i.e. you'd need to calculate the amount required for the alcohol tolerance of the yeast (one of the reason why Lalvin yeasts are good, because they publish very extensive data.....), for instance, if it's a yeast that has a tolerance of say 14% ABV, then you'd have to have enough honey for maybe 15 or 16% ABV - so that the yeast dies off when it's reached it's 14% leaving the sugars of 2% alcohol.
Or even make a batch that ferments dry, then back sweeten it.
Anyway, yes you can rack it. If it's still cloudy, but there's a fair amount of sediment at the bottom still rack it off, the rest of the cloudiness should drop out over time. Besides, it depends on the yeast, some need to be removed quickly as they can give "off flavours", other's are fine left where they are until you're ready to bottle.
I normally rack them off.
Have a look round to work out what you want to do about racking loses and reducing any head space in the fermenter once it's racked. You can use water, or honey/sugar or sanitised glass chips/marbles etc it's up to you. Just remember that if you sweeten with a fermentable sugar, then it's possible that you might start it fermenting again.
Hope that helps a bit....
