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. ->mick2 said:Well mine has a sputtering under 3000rpm. 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?
guzzigeezer said: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.
The CR8EIX is $6.09 at Advance Auto Parts stores. In SC.ferdi said:ecka00 said:Anyone have a preference on spark plugs? So far I've found:

mine has still CR8EKB mounted, next one will be CR8EIX (iridium one)

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. If something similar already exists let me know but I'm going to assume not at this point. Below our some incomplete items that will require additional research on my end or feedback from the forum and I also welcome any suggestions for additional information. If this works out hopefully we can get whomever manages this forum to place this statically at the top of "stelvio chat & tech".

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.
Did anyone help you with this question? I too would like to know how to id which engine I have in my 2015 Stelvio NTXplease advise how to identify whether your Stelvio has a
A5 or A8 motor as the exhaust valve spec is different?
