Hello newbie here I'm Ant New to this forum. Used to spend plenty of time on car forums so bikes are a nice change. From the midlands area ! And I'm currently on my 2nd 125 and I'm enjoying my Ybr but wishing it had a bit more grunt like most owners! Been riding for just over two years now That's all I think

First post on the forum having had a good look around! Right I know you can't really add any more power to a ybr but I've been doing my best to make it perform better. I've read about the Egr valve on the side that comes out of the exhaust. From what I've read it sends exhaust gases back into the airbox to help with emissions. But after having a look myself if seems the exhaust does blow into the pipe work but when it reaches a one way valve next to the airbox its turned into sucking!? So does it actually help draw air into the box and Not hamper the intake like I've read?!?!?? PIC}
