Exhaust modification for Fuel Injected (EFI) 2010 model
I have a 2010 EFI Ninja 250 R. I want to do a full system exhaust mod from Yoshi / 2 Bros / Area P.
1. Does the bike need to be re-tuned for these to work properly? Or can I just get it fitted and start seeing improved perf?
I'm assuming re-jetting can't be done because there are no carburettors?
Also, I don't have any dyno tuning centers anywhere close to me.
2. What do I do with the O2 sensor? Yoshimura folks said I'd need to install an O2 sensor bung, though they have not tested their exhaust system with EFI models.
Is this accurate? What would happen if I don't 'bung' it? What happens if I do?
Please help, I am a noob when it comes to mods.
