[hi im a new]

hello, yes you could start by upgrading the air filter, performance exhaust, and maybe put better reed valves on, think that's about it if you don't want a bigger engine displacement upgrade,

Thanks.

cheers mate, i already have a bmc air filter in the bike but i didnt know if you could do any remapping of the cdi unit or whichever, i have been looking about for a exhaust but im strapped for cash at present so im gonna wait but for what the bike is it is amazing and isnt exactly slow lol.

hey this question is probably always asked but is there any mod on a yamaha yzf r125 (2008 reg) to make it more powerful/quicker apart from a 150/180cc upgrade

many thanks
