Faito 3mm Jack-up Crankshaft for Yamaha 135LC, Lagenda 110, Modenas Kriss, Honda EX5, Wave, Wave 125

faito-jack-up-crankshaft — Faito 3mm Jack-up Crankshaft for Yamaha 135LC, Lagenda 110, Modenas Kriss, Honda EX5, Wave, Wave 125

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.

Original Yamaha 135LC Big Valve Head (Intake: 23.19mm, Exhaust: 20.13mm)

yamaha-135lc-big-valve-head-ori-13 — Yamaha 135LC Big Valve Head Original

Using big valve means allowing for more air and fuel mixture to enter the combustion cylinder for more power delivered to the crankshaft. As usual, any modification that relates to increasing the power (hp) of the bike will increase the fuel usage.

This original Yamaha 135LC head is coated with copper. Why? This copper coating comes stock from the factory. It is used to make the slip much more heat resistant and also scratch resistant. When the valve got bigger the stock slip become much more thinner, so copper need to be adhered to the valve seat for protection against heat and scratch.
