Gilera Citta

Technical | Guide


1.Often just starts well, even without a choke
2.Sometimes add a lot of gas to get it stationary.
3.Stutter just before power band
4.Little / less power
5.A lot of smoke from exhaust

Contain (bluuuuuh sound) = THIS HAS NOT BAD! The mixture just won't ignite because it's too lean, so put in a bigger nozzle!

Even if you can accelerate very carefully because otherwise it will turn off, the nozzle is too small.

1. Just makes a lot of revs, pulls hard
2.Bluuh sound
Tricky gas reaction, stuck in revs
4. difficult / no starting when cold
5.Is often very high idle when the engine is cold

With a hot runner, the piston and cylinder become so hot (expand) that the piston and cylinder wall 'damage' each other.

The piston damages the wall of the cylinder, which can even result in blockage of the rear wheel (quite serious: a hot runner can only result in less force / loss)

It is advisable to check your citta, to see what the damage is. The cause of the heat runner is the cooling, which is often caused by the wind and the petrol mixture. Is your carburetor well adjusted? if it is too poor, this also results in poor cooling. Was it by chance very hot?

A jammer has more disastrous consequences, a hot runner can cause the piston to jam in the cylinder wall, but a jam can also occur due to, for example, poor crankshaft bearings or other mechanical defects.

Cp engine block: 6V /15W front, back 6V / 5W
CDI engine block: 6V / 15W front, back 6V / 5W, Brake 12V / 15W

First you remove the clutch, and then the flywheel rubber.

Adjusting the contact points is not difficult, just loosen the screw, turn the contact points, turn the crankshaft so that your contact points are open and then measure the opening until you have the (0.45mm) right distance

Spark plug VS nozzle

Color should be coffee brown and dry
Black and greasy is too much fuel = nozzle smaller
White is too little fuel = nozzle larger
