    TPS Fault on Stelvio NTX (2012)

    Ha ha - so you did Scott - and I made the fatal mistake of eliminating that issue because I did the spark plug cap change when Stelvio was relatively new. Back to basics. One quesiton - will a bad coil and bad HT lead throw up the same fault code? Regards Alan NZ

    TPS Fault on Stelvio NTX (2012)

    A development: After convincing myself the problem is a TPS issues, because I thought the bike was not missing, I have just found two new stored codes on the Stelvio. P0136 Lambda sensor (right): invalid signal; and P0351 Coil left: to low. The coil fault would suggest I am getting a miss (is...

    TPS Fault on Stelvio NTX (2012)

    Thanks Scott. I was aware of the plug cap issues and replaced these with the NGK caps early on. I also put cable ties around the cap body, with a vertical tail, so I was pulling on the cap when removing (as well as levering from the access hole). The hesitation does not appear to be a misfire...

    Stelvio Seat

    I had a wedge cut off my seat from 25mm rear to 0mm at front - and replaced with original cover. I found the downhil slope uncomfortable. This has improved comfort and slightly lowered the seat. Alan NZ

    TPS Fault on Stelvio NTX (2012)

    Thanks Steve. The diagnostic tool I used showed a smooth TPS graph through the throttle range. I could not see any jumps/dips in the curve. However, the fault is ramdom (not consistenty repeatable) so may not show problems when the bike is cold in the workshop. Alan NZ

    TPS Fault on Stelvio NTX (2012)

    Thanks John. I will pull the lambda sensors out and clean with heat. Would damaged lambda senor(s) cause the throttle hesitation I described? Regards Alan NZ

    TPS Fault on Stelvio NTX (2012)

    Do TPS go bad? My Stelvio has developed a ramdon, intermittent hesitation at mid-range which is not repeatable i.e. at certain revs. This disappears if I tweak the throttle (change throttle position up or down). The bike does not miss - so does not feel like an ignition problem. I have reset the...

    Rack on Trax top case?

    What about an alloy plate with holes in it attached with spacers about 1" off the top of the lid? Front and rear bent up at 30-45 degrees. I've seen these mounted on the top of some panniers. If you can find a photo you like I'll do a CAD file for you. Alan NZ

    12v Accessory socket

    There is a clip on YouTube on how to modify the Trax locks so you can unlock and remove the key. I did this. It's an easy mod. Insert the key, remove barrel retaining clip, file off the little stop on the barrel step, reassemble. Made sure you leave the key inserted when doing this or the brass...

    CalSci type screen modification

    Attached are the dimensions to my stock screen calsci type modifications which has produced great results on my NTX. It worked for me but bear in mind: I am 5'8" (1.73m). I have removed 60mm from the top of the stock screen and fitted a Wunderlich spoiler. I have removed a 5-25mm wedge from...

    Exhaust header stud

    No didn't get to whanganui. Have been doing a few local rides on the falcone. Not been riding the other guzzis at all.

    Exhaust header stud

    Thanks. Good advice.

    Exhaust header stud

    I lost a header stud and the other nut on my Falcone yesterday riding home. I think one of the threads In the head may be worn. What's the recommended fix. Helicoil and replace the stud with high temperature loctite plus lock wire the nuts? Or no compound on the studs? Alan NZ

    bothersome maybe buyer with question

    Not that I am aware of. One did fail on my quota but that was because I fried the wires on a header pipe. Alan NZ

    Adjust Stelvio Idle

    Yes very helpful when I did mine.

    Adjust Stelvio Idle

    I've often wondered the same thing Dave. I assumed it was too complicated to have the butterfly opening mechanism and TPS on the same shaft?

    Adjust Stelvio Idle

    Agree. All adjustments are on the left on the Stelvio (apart from idle air screws). Sacred stop is on left TB. Relative adjustment of RH TB is also on the left. Alan NZ
