is it worth it to adcance the timing on the yfz's cause if you gain top end wouldnt you loose top end?

i dont know as how i lost bottom end or gained top end... it felt like the biggest difference was how quick it revved, and the mid range felt stronger... but it just feels like it winds out quicker

you actually retarding the exhaust cam....what ive noticed is that it does **** the power up in the rpm curve with little to no loss in bottom...the only this that sucks about the mod is that when its warm its harder to start
