Tuning carbed 124

[BBQBIKER]

I've got a new 124 S&S with Super G and IST ignition. Just did 1,200 break in miles so I believe the rev limiter is off. Motor is running out of the box jetting and currently have a Thunderheader pipe. New pipe will be RB Racing Pro Stock, on order since 3/28 so I should see it any day hahahahahaha

Bike runs superb now. I presume a little rejet will be required for the new pipe? Been looking at RB's AFR meter to dial it in or am I wasting $$$?

I use a FAST afr meter, it has a good sized digital display. You can use a single or a dual o2 sensor and it will data log.

Afr monitor is essential to tuning a bike

Suggest you consider a Innovate MXTL or another wide band meter instead of the RB meter. The problem with the RB is that it uses a Bosch narrow band A/F sensor. They say the lights read from 18/1 down to below 11/1 but the narrow band sensor is only accurate from 14/1 to 15/1. With the Innovate wide band you get accurate readings over a wider A/F range and it also costs less money.
The RB meter is ridiculously overpriced for a system that is narrow band and has no logging capability.

Thanks Frank/John/Merc. Just received the pipe on Sat and haven't had time to play with it yet. If I go the AFR sensor/meter route, is there any reason to keep it on the bike after it's dialed in? I run a speedo and thats it. No tach. No stereo. I'd pay a fee to use a meter for a week and then send it back when I'm done, security deposit our whatever else. Some say I'm cheap  Running a 31 intermediate and 76 main now. Gonna put pipe on this weekend and see what I need to tweak. Thanks again for all the advice.
