Wr125X Tuning

chriswdawson · Jan 15, 2015

I have a yamaha wr125x and have just bought an arrow exhaust and k & n air filter. A local dealer tells me i need an adjustable fuel controller in order for them to tune it and get the bike running right after i put these parts on. Has anyone else had there yamaha 125 dyno tuned? If so what fuel controller did you use? I have found one for £100 on ebay but i have never heard of the make before, its called magnum. Any advice on the topic would be much appreciated

A friend of mine fitted an arrow full exhaust system about 2 years also with k&n panel filter on his wr 125 and its been fine without a remap but to get the best out of it will be with a power commander and a custom map on a dyno expect about 12/13 rwhp

Yeah i realise it would probably be fine without the remap but just to be on the safe side and for peace at mind i wouid prefer to have it done

do you know what type/make of power commander to get or where i might find one?

Thanks
