Q: Love your new technical section on the new site, so I thought I’d join in and throw you just a quick one.
I’ve just fitted a slip-on exhaust silencer to my Honda CBR 600 RR and I was wondering if I’ll have to retune the bike to keep it running properly, simple as that and thanks?

A: The problem, or not, with all modern day superbikes is that they cannot have the fueling altered using the standard and ‘sealed’ ECU, and don’t let anyone tell you different.
The only way to set the fueling perfectly is by using a Power Commander or similar device that ‘piggy backs’ on the original Honda ECU unit. It will then have to be set up by a person who knows exactly what they’re doing with these types of devices and doesn’t just ‘guess and try that’, so be careful whom you take the bike to please. And it can cost you in excess of R5,000!
But to be honest, just fitting a replacement slip-on silencer doesn’t warrant the expense of fitting a Power Commander or the like, as the CBR 600 RR will run fine with no problems at all, besides more noise of course.
