Default TPS Reset? Why and How

I am curious as to why and how you reset the throttle position ?
How would this effect throttle response?
How do you know when you need to reset it?
I recently made changes to my intake and exhaust, but did not consider a tps reset....do I need to?
Bike runs good...some snarl and backfire on decel, but nothing bad...
does it make sense to reset?

TPS adjustment sets the strat point in the map that your bike works from. By establishing mixture at idle; you effect the mixture throughout the range. TPS adjustment can only be done by a dealer wirth the digital wrench program on post 01 bikes. Done right it can pretty much eliminate popping, and other drivability issues

I had read somewhere that the Lloydz fella does the TPS adjustment-- was he able to purchase the tool/program to accomplish this or is he blowing smoke??

Thanx

Lloyd has what it takes to do TPS adjustments. You will find he rarely blows smoke

I would never imply or say he would-- I know better than that, Just maybe the fella that wrote it was telling everyone a line---- thats all.

I found this info on how to do a manual TPS reset:

Key on, switch on, engine off
Slow 5 count rotate throttle from closed to wide open
Hold throttle wide open for slow 5 count
Let throttle SNAP shut/closed
Cycle kill switch (off then on)
Start bike, and enjoy the ride

Do this at your own risk (if any)

This does not reset your TPS. What it does is re-establish your base throttle points. So the ECM knows where idle, and wide open throttle are in the whole scheme of things. It will only help, or change anything if for some reason your bike looses it's little mind.

Should I try this after recalibrating for new intake and exhaust?
I am getting popping and backfiring on decel, but not sure if that is to be expected due to the new pipes. Also, there seems to be a good amount of play at the beginning of the throttle, like I have to turn a good amount (maybe 1/8th of a turn of the throttle) before the engine responds to the throttle.

Throttle cables definatly need to be adjusted, but it also sounds like TPS needs to be adjusted for your pipes

thanks toejam and Kevin
Took care of this yesterday.
Slight adjustment to cable and TPS reset as above....works much better!
Less play at the beginning of the throttle makes for more control, especially
at lower speeds. Took the bike for a nice test ride....loved it!
