Hi guys,
almost 3 days now been trying to see whats the best way to convert our mags from drum brake to disc brake using local parts available.
from local forums, ive read that kawasaki HD3 and yamaha RS100 sprocket hub will fit.
i bought those two hubs and i found out the Kasawasaki HD3 hub is the best for our stock mags.
3 days passed and still modding...
our stock rear mags bearing code : 6301
regarding the bearing that will fit with hd3 and axle rod,
this is the hardest part.
the good thing is our local bearing supply store is so helpful,
he gave me a special bearing 12BC04 (inside diameter 12mm / outside diameter 42mm).
this bearing is used in the flyweel/transmission of Toyota 2C engine.

its perfectly fit with HD3 hub and our stock t135 axial rod.
heres some initial materials needed: (will add more once im all done)
