first of all you must understand the different between CBU and CKD
from my understanding CBU (Complete Build Unit) were shop/importer import them in a "complete physical bike" hence tax is much higher...
but who do you think manufacture kawasaki er6/verys(650cc) for asian market??it's being produce and manufactured by kawasaki thailand....
but kawasaki malaysia import it as CKD (Complete Knock Down) where they will assemble it back in kawasaki factory here....
though i'm not pretty sure as they assemble it completely or the just maybe take down those fairing and maybe wheels and declare it as CKD hence to make the tax much lower@cheaper....

before Hong Leong Yamaha introduce XJ6 in malaysia market...
earlier there already some XJ6 (CBU) unit sold by NAZA and other importer....
but the downside is RESALE value....
as they are completely the same bike....do you think CBU unit will be sold much higher than CKD unit for 2nd hand value???

as currently what i heard that honda and kawasaki had slowly begun to build more higher capasity of bike in their thailand factory to cater for asian market.....rumors said that honda will build 400cc bike in their thailand factory....
which model is still unknown....

as for know i think if you looking for superbike above 500cc...
and wanted for BEST RESALE VALUE...you deffinately can't go wrong with either this 2 model....
CBR600 or YZF R6....
this two model is the most in demand for malaysia market....
but kawasaki ZX-6R also not bad lar.....as one forummer said...it's much EASIER to get their parts as they were sold directly by kawasaki malaysia and their bike also not bad in resale value....

CBU bike is just means that the bike is fully import in physical unit..
no matter which country it import from....
and YES...CKD and CBU are a same bike...all parts are the same
except some restriction like speed and exhaust emission depends on each country law
as to my knowledge for honda bike...
only these two model are currently assemble and build in japan which is CBR600 and CBR1000...
others model are assemble according to each region dan market...

p/s:
GSXR600 indeed are very sexy bike...

anyway new honda cbr250r doesn't have a "rabbit" look..
the head light design is more towards current vfr design which is Y-shape...

have to bring your bike to another workshop...
try to check for carburetor setting..
because from your story..
it seem just like the problem is from ratio mixture of fuel & air (maybe it's mixture too lean or too rich)
