G3 stalls when clutch fully released

Post by pintpot »

Hi

anyone got any ideas on this probelm. Bike has always run well but not used it for a while. Tried to go out on it today and when I release the clutch fully in 1st gear the engine just stalls.

Thanks

Strange. I used to find that my bike would stall as I dropped it into 1st gear because the clutch plates had stuck together but never once it's engaged gear and set off.
Erm, you did remember to open the throttle, didn't you?
Did you remember to unlock it from the ground anchor?

I know, silly comments but I didn't want you to feel ignored.

Hi

Basic fault finding:

Without the engine running:

1. Can you push the bike without undue force when it's out of gear?

1. Yes - Look to ignition / fuelling problem - No go to 2.

2. Can you push the bike without undue force when it's in of gear clutch pulled in?

2. Yes - Look to gearbox problem, (seized or partially) - No go to 3

3. Can you push the bike without undue force when it's out of gear clutch released?

3. Look to problem with the rear wheel drive system - does the rear wheel spin freely

Well it's a start

Regards Mick

The clutch plates were probably stuck. This can happen when a bike is not used for a while. And the problem is exacerbated by a too thicker oil in the primary chain case. The next time, before starting the bike, pull in the clutch lever and operate the kick starter. This should free the plates.
