started to clean up my bike tonight since she is dirty and grimmy from its long life.. anyways i noticed the atac system on them... i got a little bit of info on it threw searching google..
but im not understanding it fully.. im guessing its a early power valve system??? since it was replaced by the HHP set up.. Read that some people remove it by installin a aftermarket pipe ( im looking to get a dg national pipe for it) which removes that.. BUT what are the effects of removing the atac in favor of aa/m pipe??
BTW my bike is a 84 honda cr125r.. stock except for a old school answer s-a pro spark arrestor/ silencer ( was thinkin of putting my powercore2 on it but its stupid loud with the pc2 on it)
im a bigger guy, 5'11'' 255 so i dont want to do anythingt hat will hurt the little bit of low end it has,
