The Ikeya Formula sequential shifter converts conventional H-pattern shift to a sequential up and down shift mechanism.
The clutch is still required, but the movement is dramatically simplified. The biggest mistake one can make when buying one of these shifters is not adding the Shift indicator. 100% of the time every customer comes back for the indicator and it has to match the serial number of the shifter. We have added the indicator with every purchase.
When you push down the shift lever, the drum in the SEQUENTIAL SHIFTER starts rotating. This drum has grooves which control the left and right movement of the lever. It means 1st ->2nd gear change produces a right direction movement due to slant cut grooves. This movement repeats from 1st gear ->5th gear.
The back and forth movement is controlled by rotating the crank which is connected with the drum by the gear. This crank rotation enables the crank plate which is connected to the shift lever to move back and forth. This crank plate moves left and right because of the bracket movement which is fitted in the grooves. Due to the combination of these two movements, if you pull down the lever from the neutral position, the lever pulls down to the left front. If you pull down the lever one more time, it moves to the front first, then moves to the right and then to the front direction again.
