Almost all motorcycles are manual, and have a gear lever (not like a car, but a foot-operated lever) typically on the left hand side, in front of the left footrest, so that it can be operated by the left foot (some older British bikes have the gear lever on the right hand side). The order of gears, from the bottom, is 1-N-2-3-4-5-6 (some motorcycles may have 5 gears or less, but the order is still the same). For example, if you are in first gear, to change up to second you will throttle off and simultaneously pull in the clutch (left hand lever), then shift the lever up using the top of your boot (it can get stuck in neutral when you are starting out), and then slip the clutch and and apply throttle again. Changing down from third involves pulling the clutch in and throttling off again, and then pushing down on the lever with the sole of your boot. It is good practice to also "blip" the throttle when you are changing down and the clutch is in, so that when the gears re-mesh they are in-sync and the change occurs more smoothly - this is also better for your motorbike.
If stick shift jumps outta second gear is it okay to drive the car?
Your top gear or last gear you shift to. Depending on what make and model of your bike, either 4th or 5th on motocross bikes and for woods bikes it would be 5th or 6th.
Cable too slack.
No it will shift slow.
Most motorbike gearboxes are pretty bulletproof, I have found most problems to be in the shift machanism,usually the adjustment on the gear change hub and arm.
When shifting from first to second gear in a manual transmission vehicle, you need to press the clutch pedal to disengage the engine from the transmission. Then, while keeping the clutch pedal depressed, move the gear shifter from first gear to second gear. Finally, release the clutch pedal slowly while simultaneously pressing the gas pedal to smoothly engage the engine with the transmission in second gear.
If would not be bad for a car engine to shift from third to second gear if you are traveling at 30mph.
Worn synchonizer?
A 93 Deville that wont shift from second gear has most likely got an internal transmission problem. Unless the linkage is mis-adjusted, then the problem is onside of the transmission.
The transmission computer will default to second gear only when it detects a malfunction and sets a code.
the spark timing has to be adjusted (on older vehicles only)
There are several causes that an automatic transmission will not want to shift into second gear. The two most common causes are transmission pump issues and trouble with the vacuum modulator.
