An expensive wideband tuning system made this bike run WAY WORSE! 

You guys really make it interesting to watch your video's! Keep up the great work!

Excellent explanation. Keep up the great informative videos.

Hey that’s a great looking bike! 😉 Thanks for the help.

Question: why not fix the exhaust leak?

Exhaust is sound waves. That helps me wrap my mind around it.

The main takeaway: don't buy cheap exhausts

Calibration is another thing to consider. Lambda output at certain AFRs versus ECU expected input at certain AFRs. Might not be an issue with this system. I'm not familiar with it.

shit. tonight i just drilled a hole to weld a bung in a similiar location about a 7 inches after the header pipe connection and a foot before the slip on. and its an amazon slip on thats on an amazon exhaust so the fit isnt that great. BUT my bike is carb not efi so it has no ecu. im manually tuning the carb am i ok because i can adjust manually for any leak that might affectt he wideband sensor? or should i heat wrap the pipe or use some kind of exhaust pipe clamp for the slip on?

Great video. My group has 3 track bikes all 2015 R-1's that you guys tuned, have the wide band, you programmed for them, will inspect bikes with these ideas in mind. The issue?, we have had problems with throttle chop and just accepted it as normal, deal with it. Track only bikes. Difficult to crack throttle transitioning from entry to corner maintenance. I have also read a bit about bike computers having a setting to shut off fuel on deceleration. I assume that if it is there you would turn that off for a track bike?

So if the customer fixes the exhaust leaks, they can use the wideband again? I have always wondered why nobody uses fullwelded exhausts on their bikes. I know those "slip" connections will not in anyway be secured enough to avoid leaks. Some of them will hold up at lower rpm runs but when you go wide open and the rpms climb, the vibrations can loosen up those connections and cause the leaks.
