Anyone have a preference on spark plugs? So far I've found:

NGK PMR8B ($14 per)
NGK CR8EKB ($10 per)
NGK BPR6ES ($7 per)

I am the new owner of a 2009 Stelvio with 7400kms on it. Love the bike. I am old school and new computer fuel injection system are beyond my back yard mechanical skills. I have been told the fuel system can be a problem. Well mine has a sputtering under 3000rpm. In traffic it can be frustrating when turning slowly at a light.
It also sputters in third or fourth gear holding down 50kms a hour or 30kms in a school zone. The dealer said this has been a problem with this model and they are working on a fix..Some sort of resistor in the fuel/computer signal.

Is this well known or is this just my Guzzi?

It could be just your bike, when was the last service done? Ask if the TPS (Throttle Position Sensor) has been checked/reset, and what map the ECU has on it. If all of those are good, 3k RPM is a troublesome spot, and I have a few solutions to fix it. There is a few band-aid resistor fixes, one is posted on this Forum. If you want it to run perfectly and don't mind spending a little money to get it there, contact me direct e-mail; Todd at GuzziTech.com, or if you can see it, use the small envelope/link below my picture to the right. ->

I'm a noob to Guzzi's although a geezer before arrival even. I just acquired a new Stelvio this past Wednesday. I'm preparing to do my first valve check/adjust when the service is due. The mechanic at the dealership told me they (Guzzi) changed the valve clearance gap from 4/6 to 6/8, intake/exhaust on the new Stelvio. Is this correct?

This is a great forum with lots of information. I'm looking forward to getting the few kinks worked out on the first service and having a smooth running machine for many miles to come. I'm doing valve check and oil changing but letting the local dealer do the throttle balancing and syncing which I don't have a clue how to do.

You are correct about the valve clearance being changed to 6/8 (0.15/0.20 mm). The sticker on the bike still shows the old spec also. This was a last minute change by Guzzi and was confirmed on other posts and forums. My dealer says he acutally says the spec is actually slightly bigger but I am sticking with the 0.15 and 0.2.

As for the throttle balancing and syncing it is actually easier than you think. Pick up a vacuum balancer (I have a Carb mate and love it) and the software (centurion S, from Todd here at Guzzi Tech). Up front cost is about $350 or so for both but you will get that back quickly after saving a couple of trips to the dealer. You will keep the equipment and use it for the life of the bike. Not to mention that you will have piece of mind that the dealer did it properly. Had my dealer do mine under warrenty and was still slightly out of balance at 0.5 cm hg at idle and high speed snyc. Just waiting for my software to show up and she will be re-sync'd. Will really help you dial your bike in for optimal satisfaction.

Going with the theme of everything a Stelvio owner might want to know:

Stock exhaust, 4000 rpm = 90dB

(Did a dual sport rally this weekend and a sound check was required, standard SAE J1287 JUL98)

The original Hella foglights on the Stelvio stopped working.
Checked the relay coil voltage and across the coil pins were switching correctly.

Ended up being the Tyco Relay part# PA66-GF25.
To confirm the diagnostic I interchanged it with the headlight relay .... well I wasn't going to Portugal to get a replacement. :)

For us North American dudes Foglight or Headlight relay
Tyco replacement:
VFMA-15F41-S01-ND
RELAY AUTOMOTIVE SPDT 12V
Googled the part# ..... Electronic Component distributor ..... I received it in 2 days

UK owners;-
Just taken my 59 plate Stelvio for its first MoT test (govt. test done after 3 years thereafter every year testing various parts of the bike) and it failed.

The headlamp reflector is not legal in the UK and throws too much light too high to the right.

Haywards supplied me with the fix that fits behind the right hand lamp. (see pic)

Great idea - good to have on hand - just a added note re: oil grades -- pending on the time of year and cilmate the bike is in regarding cold starts - 10w-60 is like syrup this time of year in northern BC so I use a full syn 5w-50. Besides 10w-60 is special order in any brand. Mid summer or trips into hot country switch up to 10w-50. The recommended 10w-60 required by Guzzi in a 8V and PDI'd at the dealership blew out a o-ring for the sparkplug well on the valve cover with less than 180 miles on the bike. The oil level was over full by 300mils ( a coke bottle full). The only oils close to spec suggested are Royal Purple and Amsoil in these parts. Its either Castrol or Mobil - Redline is no longer available. The nearest Guzzi delaer is a 12 hr ride. So filter consist of Fram 6022 or Fram Ultra Toyota Prius - Napa - Donaldson or mail order a box of IFO. The nice thing about the Fram 6022 is the cartridge is up inside the casting, where as the IFO protrudes and not much air space between it and the skid plate. Back roads on gravel tend to have gravel lodge in there and if a bottoming on the skid pan ocuurs - well goodbye oil. Although the IFO has a tough heavier filter canister but we have some sharp BC rocks. I added a lower frt fender extension and oild cooler guard as backups out of shop handy materials ( a bar-b-cue grill for cooking veggies and a 4" 22* ABS pipe elbow). No Patent !! :woohoo:

please advise how to identify whether your Stelvio has a
A5 or A8 motor as the exhaust valve spec is different?

All, There seems to be a need for a "what new owners need to know" and "quick reference for existing owners" all in one post.

I just set mine at .1, .15 as my manual says on my 2013 NTX and it ran so much better it was amazing. Bike had 3400 miles on it with no previous adjustments I am sure. All were loose to be sure, especially exhausts.
