Planning a first intervention - really confused.
Due to lack of knowledge. When you lack a technical background, to have a complete and deep understanding of motorcycles, a lot of information you receive can seem contradictory.
I want to make a first step to improve what I understand as the weight/performance ratio of my yet unmodified XT660Z.
Since the particular bike has a really heavy exhaust, I thought I would start by replacing it with a single. Then it was further explained to me, that along this such a modification, another one is necessary, that of the air filter and thus fuelling adjustement is going to be needed too. This is were things get out of hand for me. As far as I understand, the installation of a power commander, or what many technicians here call a "parallel brain", is needed so that it provides the proper width of adjustements.
So if I understand correctly, the procedure would be like:
Installing all 3 components and then mapping the motorcycle with the help of a dynamometer apparatus to achieve a good rpm/power ratio and avoid damage of the engine.
Am I getting this correctly? Any propositions? Can you direct me to the proper threads to study? I also have another question: What's the role of ECU remapping in all this, especially in relation to the power commander? Is it a needed step too? Is it unnecessary when a power commander is involved or does it synergize with it? Can it really be done remotely as OTR claims?
As for the exaust I visited a popular local manufacturer in my city. He explained to me, that going for a full exhaust system replacement is pointless in this bike, for the material, cross section and general design of the pipes are already proper and he can do nothing better. In other words, only the muffler and connection pipes are to be replaced.
Well as you understand, my understanding is quite basic and lately I'm trying to educate myself by watching videos and reading articles and threads.
Please make this clear to me! Thanks in advance!!
