Hello friends, I have a YD100 with médium porting, and expansion exhaust pipe. I live at 4500 feet of altitude, the question is: how many degrees should the ignition be to have the maximum power at medium RPM.
 
The only parts of this that are helpful are engine type (76cc 2 stroke) and altitude. Nobody knows what porting you have or which expansion chamber. What's your header length and stinger diameter? Nobody can help you correct your timing till you know what it's at, can you tell us your current timing?
We need a little more help to help you :unsure:.

Greetings, the ignition timing is the standard, the one that comes with the engine, my question is: for an altitude of 4500 feet, how many degrees do I have to advance the ignition timing? This is independent of the porting, type of exhaust or engine preparation. The ignition advance is given according to the operating altitude basically. Anyway, if you want to know about the type of engine I have on this bike, it is a YD100 (79.6cc) engine, it has the CDH TYPE 66 exhaust, the cylinder is slightly ported in the intake, exhaust and transfers.
