OKAY...going over right now to have my friend complete the final welds(2).Should be up and running early eve tonight.This is gonna be GOOD methinks
It's not that it's idling better, it's just that you can now hear it idling. A/F ratio will be off but most likely on the top end. You would be safe enough to ride it around moderately until you send off the ECU.The Akra muffler comes with a DB killer(installed).It's now got a particular 'GP' growl to it.If I didn't know better,I'd say she's actually idling better.
You still have the stock O2 sensor connected?I have a question here for you guys that've done this.Does this mod affect the fueling at all?Will it be 'lean' now?Or can I ride it like this before I get the ECU off to Don?
This would be a good question for Mr. Guhl. But, it is my understanding that the O2 sensor and closed loop operation is in steady state throttle "cruising", which is strictly for emissions reasons only. When the bike starts to accelerate the ECU switches to open loop. It's for this reason that even if a bike has an O2 sensor you should still tune for a proper A/F ratio, particularly at wide open throttle and on the top end since the ECU will be in open loop mode. Once again the O2 sensor and closed loop operation is for emissions only and not performance.You still have the stock O2 sensor connected?
It looks like it in the pics.
If this is the case,your fueling would not change at all.
The O2 sensor is before the cat,all you've done is removed the cat and muffler,so to my way of thinking your A/F will still be closed loop controlled by the ECU.
