-  * With the rear wheel off the ground, shift into 1st gearThen, rotate the rear wheel forward until it stops (this will turn over the engine / transmission). \\ You can also just turn the wheel over with one hand (a bump at a time) while shifting with the other. The wheel doesn'​t have to turn too far or at any rate of speed.  +{{:​techtalk:​evo:​engctl:​1998_1200s_coil_4_by_hippysmack.jpg?​direct&​300|}} {{:​techtalk:​evo:​engctl:​1998_1200s_coil_5_by_hippysmack.jpg?​direct&​300|}} {{:​techtalk:​evo:​engctl:​1998_1200s_coil_6_by_hippysmack.jpg?​direct&​300|}} ​\\
-  * Then you can shift thru 3rd. +
-  * It takes two separate movements of the shift forks to get into 4th which requires turning the wheel again. +
-  * Then you can shift to 5th. Of all the gears to be in, 5th will be the easiest to turn by hand.+
