like the title say. WTF is a ignition advancer? is it like a chip for the bike?

 

help make more power at low rpm which translates to less hesitation in real low rpm and more useable power at cruising rpm, you feel the bike accelerate harder from a stop, i dont think alot of people really do this mod, usually helps after you do exhuast on the bike

 

This is a advancer:

It mounts on the end of the crankshaft, It spins and a "pickup" reads those tips on it. When the pickup gets the signal (when the tip of the advancer passes the pickup) it sends spark. With the advancer this process happens alittle bit sooner (or advanced) which results in better low end torque /response, and better startup. I havent gotten an advancer but I have entertained the idea.
