Hi
I am posting this for any of the other 'newbies' that are thinking of attempting to service and 'remap' your pride and joy.
I am a returning rider who, after raising two kids, has got back on the bike.
I have a 2012 Stelvio NTX with 28,000 kms on it.
The previous owner had put a after market exhaust on as well as installing a K&N air filter.
The bike has been 'rollerised' (allegedly by Pete Roper, apparently during a "busman's holiday" in Tasmania
)
I had been using the bike as a daily commute and it was starting to pop and fart on over run as well as some harshness at idle.
I am a competent home mechanic but this is my first bike with fuel injection and electronic engine management.
I downloaded a few of the Pete Roper pictorial guides (Adjusting the valves)
So on Saturday morning I started.
Sparkplug removal was easy as long as I followed the instructions and I used long forceps to gently pull the plug covers off.
finding TDC was very easy as was setting the inlet and exhaust clearance.
I installed new plugs and replaced the battery (unable to maintain charge - approx. 4 years old?)
Everything went back on as it is meant to.
Bike was quieter and more responsive, but still a bit harsh at idle.
The bike came with the cables to connect it up to a laptop.
I live in a "Apple" house so I had to buy a second hand windows laptop (ex-Government).
The Guzzidiag software was a very quick download and install.

The best place for the Pictorial Tutorial was found on "Beetles" website
https://www.griso.org/I used the reader to save my existing map.
I don't (as yet) have the skill or confidence to make manual adjustment using the diagnostic so I went the "Beetle Map" experience.
I paid for and downloaded the "Stelvio" map (Using Paypal).
This was then "written" into my bike in approximately 15 minutes.
I reset the TPS values as per the Pictorial instructions and packed everything up.
Had a great test ride through the Hills combining switchbacks and freeway riding.
Popping and farting on overrun is virtually gone, the bike is much smoother and feels a lot more responsive.
All in all a very easy few hours work that I felt very confident in attempting.
I had read as many of the posts as I could and felt in control at all times.
That said I was very relieved that it all worked well when I fired up the bike for the first time.
Thank you to all that have posted on this site regarding their experience and expertise, reading and absorbing the information certainly helped.
