Help me about Wiring diagram of Spark 135

Great explain!

I don't think CDI of T135 had an micro-processor in it with the price in Vietnam is 550,000 VND (equal 50USD) !!
I think the pink wire will increase the bias for inverter circuit when it connect to mass and then the high tension for spark plug increase also. Yamaha connect the pink wire to mass on the 2nd gear because at this gear the vehicle need an powered torque for increasing speed before use the 3rd and 4th gear.
I'd tested the pink wire connecting directly to mass (without gear connecting) and I was surprised the power of engine like a hurricain !!! And then I must change the rear sproket from 39 (original) to 34 !!!

The TPS I have not yet to change for testing but I think the TPS is protect circuit only for engine, not an effect for changing the angle of advanced ignition. I will test the TPS and post the result.

how can i cannot see the page???? just blank page............. :cry:

THE CABLE that connects to the 2nd gear was meant to prevent hiccups when you close the throttle suddenly, this info was told by authorized YAMAHA mechanic, this was implemented in the 2nd gear because usually you stop and go frequently on that gear position

one more thing, the standard CDI has 39 (!) ignition mapping controlled by the TPS sensor, so the correct mapping will boost your engine power and vice versa.

Better not to change the original CDI and stick with it for safety diagnosis reasons.

the standard setting from the factory limits your engine rev up to 8000 rpm, if the TPS adjusted to 0,6 - 0,7 V (0,5V is the standard) the engine can rev up to 9600 rpm max.

And the only way to adjust the TPS is to?

untighten the TPS screw, plus a multimeter set to DC Voltage (V), plug the positive to the blue wire, the negative to the yellow wire (use a needle clamped with an alligator clamp from the multimeter). While you're still doing this move the TPS clockwise and see the reading on your multimeter

so multimeter read as....what?

my..my.. set the TPS clockwise until the multimeter shows voltage range of 0,6 - 0,7V

tq dude. is it really efisien.hehehe

Yo haen, got a pic of your bike? From what I see in your modification specs, it sounds really interesting, especially the KOSO digital tachometer. Be kind enough to share?

wow that is great
