What is a shift kit?
A shift kit for the FJ is nothing more than a stiffer spring which controls the foot lever pressure. It makes it a bit trickier to shift but it solved the missing shift problem I was having. The spring is on the shaft from the foot lever on the RIGHT side of the bike. The engine side-cover is removed and the spring is accessed.
A. The kit is an aftermarket service pack that has been researched and developed to compensate for design deficiencies discovered in a particular transmission. In most cases, the kit improves the quality of shifts, increases the internal pressure that operates the unit, and provides better lubrication.
