| * With the rear wheel off the ground, shift into 1st gear. Then, 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. | |
