Ok guys i have a 07 1000rr and i recently put on a yoshi r-5 carbon slip on and power commander. I also had the bike dyno tuned. I just had it out the other day finally after it getting tuned. The bike idels like it has a cam in it really low and just wa wa wa wa hah like how a bike wit cam would sound and also when i get on it and let of it back fires a good bit. Is any of this normal after you spend 270 on a dyno tuning?????

 

No, its not normal. Something isn't right somewhere.

 

Suppose that depends on the guys with the Dyno! Obviously the mapping does not sound right. Is it actually backfiring as if it has unburned fuel, or is it popping like when you downshift at higher RPMs? The other thing to check is with the slip on is there a good seal or is it flopping around? Did the O2 sensor get removed when the slip on was put in place or is it capped?

 

I said more sputtery if that makes any sense to you. like crackels. and what is the o2 sensor and the slip on just slides onto mid pipe there is a clamp but not a welded seal

 

have you tried adjusting your idle? i've never owned anything newer than 94 so i dont really know ur exact situation

 

I have tried adjusting it but dont realy help much

 

At the very least, you've got a bunk map. You need to take that thing back to whoever tuned it, and ask them to have someone who knows what they're doing make you a map that's appropriate. Do it ASAP, or you can cause some serious engine damage.
