If the kick starter will not turn try putting the engine in third or fourth gear or even top gear and pushing it. If the engine will then turn over the problem is in the starter gears. If it still will not turn over, pull the cover over the crankshaft flywheel end, and put a wrench on the nut or bolt on the end of the crank and try to turn the crankshaft, with the transmission in neutral. If it turns, the gears are stuck. If it still will not turn, the engine is well and truly stuck ,,,

How will I know if I am getting enough sleep?

The best test to see if you are sleeping enough is to decide if you feel sleepy during the day. Nearly everyone gets a sleepy time just after lunch or eating a big meal but if you are feeling dozy at other times during the day it might be a sign that your body needs more sleep.

My aprilia af1 125 wont start the starter motor turns nd cn hear it but it doesnt engage ive tried tappin it and it still isnt engaging can nyone help

Hi, Jasonwalklin and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Bank angle sensor tripped and ignition/light key switch not cycled to the "OFF" position and then back to the "ON" position.
5. Security alarm needs a reset.
6. Starter control circuit, relay, or solenoid faulty.
7. Electric starter shaft pinion gear is not engaging or over-running starter clutch slipping.

Rear brake light switch needed gts 1000

I think AF1 had one not so long a go. Go through their used spares, alternatively, only your dealer. I'm pretty sure you could something else to work in the meantime, with slight modification.
