maintenance wise is the same for all bikes
healthy bike=
once a mth
spark plug 10 bux
gear oil 20 bux
valve=DIY if u know
if not around 10-20 bucks
now on the sensitive part, no offense to all
wif the milo kong, it is confirm a loser bike
coz firstly the milo kong has got 3 restrictor plates blocking the
air flow at the end can
one more at the stomach, plus the cone ,
but once u mod liao by removing all the restrictive elements inside
the bloody milo
once the valve open its really amazing wif the acceleration, some
friends on my bike commented that they almost got thrown
backwards
this is becoz of the different setup of the rave valve and the
other YPVS,KIPS and RC valves
the other valves system on jap bikes opens according to the rev,
but the rave valve opens fully once at a certain RPM
but then no matter wad wif the milo kong, modded or not modded, ur
top speed still will lose to all other jap bike,
but i mus say the rave valve on aprilia is bery bery hard to
maintain
u must decarbonise the valve every mth or so
and it is bery hard to remove when it is jam becoz the power valve
is made of bery bery weak material coz its light
but for japanese bike, the valve u can dun wash for 1-2 yrs also
neber mind
friend, i suggest u dun get an aprilia unless ur interest and money
is there
if ur the type who give up easiy or wanting to have a cheap to
maintain bike, then get a jap bike coz italian parts r bery
expensive
and they dun last long as they r meant for tracks and not for
road
if given a choice, i think i will get a jap bike becoz i am a poor
guy.....
