TXM's Electrical fault?

[forchetto]

You mean the switch that turns on the neutral light?. The method varies but it's usually a contact inserted into the gearbox that rotates with the gear selector cam drum. On Hondas it can be found next to the gearbox sprocket. It looks like a small black plastic thing and has a single wire going to it. The lamp receives 12 volts at one end and only comes on when that switch earths the other end of the wire.

yes thats what I was talking about,my bike has a connection with 6 wires(only 1 is used) i guess it gives you the possibility to have a gear indicator on the panel.

Do you have any picture of the mechanism?

My spark plug is grey and a bit brownish on the insulator and the electrode is getting small. The inside walls of the spark plug are black,like they have charcoal deposits all over the wall.Is this correct? What should I expect riding my bike,idle?

TMX,

If your plug looks like this it should be okay....

How much should a spark plug last? In my case for example,I've a 200cc engine and I'm all the time acelerating and braking.

On my 200 cc Qingqi it just recommends inspection every 3000 km and replacement if the electrodes seem worn down. Due to the relatively low cost I would replace it at 6 to 8000 km. Iridium ones should last a lot longer.

Anyone has ever tryed those RACING CDI.Is it real that they increase the HorsePower up to 20%? What do you think?

Not really. There are lots on the market. Most just remove the RPM limiter enabling higher revs to be achieved in tuned engines. Most claims are a scam. The fact that they claim such power increases proves that. No ignition system can do that. Ask to see a dyno test sheet.

Some of the better ones increase the amount and speed of ignition advance and the engine will feel livelier in mid-range and maybe remove some flat spots in the rev range.
Ultimate power output can not be changed without changing the maximum advance setting, and this is fixed by the position of the pulser coil relative to the magneto rotor. Whatever CDI unit you fit, it can only play with the advance curve between say 8 degrees at cranking speeds and 15 degrees maximum advance.
