strange starting problem

(1/3) > >>

hi all,since i am still learning about this bike :-[ i get a strange problem now and again when i start her up
it is that when i press starter button she just turns over without engine firing, neutral light is on,almost like electrical fault
i then shift through the gears and then back to get neutral light back and she then is fine
i have read tha haynes ,and noticed there is a clutch fail safe
anynone got any ideas :)

pae:
Could be the infamous starter clutch, they are prone to fail. Do you hear anything, like a whirring or fast clicking, when it fails to spin the engine?

If I remember, the clutch failsafe means that the clutch needs to be pulled in the bike is in gear. There's a neutral interlock that stops you from turning the engine over with it in gear, and this can be over-ridden by pulling the clutch lever in. The neutral connection is behind the front sprocket cover, the clutch interlock is on the clutch lever.

hi there,thanks for the reply :)
there is no clicking or whirring,the engine still turns over as normal,also if i try to start it in gear the same thing happens if i pull the clutch in(engine turns over fine but does not fire)then i shift  through the gears then try it when neutral   light is back on and all is fine,i might try and have a look at the neutral connection when i get a mo

Do you normally leave the bike with the fuel tap turned off? Try leaving it in the ON or PRIME position and see if it starts easier.
Sounds to me like slight fuel starvation. Running up and down the gearbox will have no effect on starting, it will however give the float bowls a little extra time to fill up.

What happens if instead of going up and down the gears you just let it sit for a few seconds ?

Spitfire:
Sounds really strange this one, so the starter turns over but the engine does not fire as if the kill switch is in the off position, and a quick cycle through the gears resets it. Most peculier !
