bobbyhollie05 Posted March 2, 2009 Share Posted March 2, 2009 i have just had a new arrow exhaust on my xt125 but on my old one there was a pipe coming of it i think it is a secondary air system valve but the new one does not have this i followed the pipe and it went to my air filter i was wondering if this will effect my bike Link to comment Share on other sites More sharing options...

windard123 Posted March 2, 2009 Share Posted March 2, 2009 Hi mate, that justs looks like an EGR valve, the engine will re'use the exhaust gases to lower the emissions when the valve opens but i dont open when your pinnin the throttle and need fresh mixture, it'll run fine without it i should think, just block the pipe up or route it somewhere out the way. It could be a diaphram for somthing tho, could do with havin a good look at it and see if it actuates anything, if it does could be important, what years the bike?

windard123 Posted March 2, 2009 Share Posted March 2, 2009 Well it could be either then, if it was an older model it would be unlikely to find EGR on it, id quickly av it out and see if it actually moves anything, if it just looks like a valve to allow flow through then its EGR Link to comment Share on other sites More sharing options...
