I just compiled this in one page as an easy reference for me to look for it later.
Quote from RB FB page:
Get a better grip for your feet by using Racing Boy’s footrest kit, not only while riding on road but also while speeding on track. It is fully made from high quality and anti rust alloy and attached with foldable alloy foot peg. The footrest kit is designed and manufactured to make sure that the riders attain the finest riding position to achieve a better control of the bike even on an uneven road. You may find various type of footrest kit at Racing Boy to fit a variety of motorbike.
Crankshaft jack-up is better than crank pin jack-up because crank pin is made from 3 pieces that is being welded together.
Faito crankshaft jack-up have the same properties of crank pin jack -up but the durability is the same like the OEM parts since the installation only change the TDC and BDC for 3mm. The offset 3mm is achieved by altering the stroke dimension right at the crankshaft itself.
The benefit of having longer stroke is that we can have bigger displacement for our bike and also better torque since, long stroke is related to better torque. Anyway, this will make the bike is not high-revving engine since high-revving engine usually have short stroke.
