V85TT Loose Bits

    It might just be my V85TT but it's worth checking your sump guard bolts. While cleaning the bike this morning after yesterdays 220 mile ride I noticed that the front of the sump guard was loose. The front two M8 x 16 bolts that secure the black steel bracket to the sump were missing. The remaining two bolts that hold the rear bracket to the sump were barely tight, I could undo them with my fingers.

    Page 204 in the service manual shows the assembly and torque figures of 20NM for these bolts. I can only assume they weren't properly tightened at the factory. It hasn't had its first service yet.

    Would a drop of Loctite blue be advisable on these bolts?

    Interesting.... I heard some slight rattling from my V85 today, especially at low revs full throttle. I couldn't make what the sound was coming from. It sounded like it was valve ticking, since today, I might have become the first person in the world to overheat their V85TT (overheat light came on). Yes, I am proud.

    I gave the header covers a few kicks to see if they would move but didn't check the sump guard since I didn't have time. But I'll check later and confirm.

    Thanks for posting Chris. I’ll put this on our service checklist. Yes, loctite on everything is best bet. It helps with corrosion issues as well.

    check the bar end weights too.
    these things are flying down the assembly line too fast for the workers to drink their wine. If I had a new one I'd go over every fastener after the first tank of gas.

    Welcome to the world of Guzzi ownership and the 'lost sump guard bolt' conundrum. It looks like sales of Loctite 243 are set to increase.....

    You're welcome. Having bolts come loose and drop off is a bit annoying to say the least but it hasn't put me off the V85TT. It's a great bike to ride and I'll be using it in September for a 3 week European tour, including visiting Mandello for the 2019 Open House event.

    I absolutely agree, the v85 is too nice to get mad over a few missing bolts!

    I am quite jealous of your upcoming tour! That sounds amazing. I am trying to talk my wife into taking a holiday to Lake Como and renting a v85 to tour around Guzzi country. Please post plenty of pics while you are on the road.

    I'll create a separate topic in the 'Ride Report' section of this website for the European tour.

    while you are checking for loose bolts... there have been lots of reports of the the seat bump stop coming loose and even falling off
    seems that the seat compressing is part of the problem, So loctite or nylock nuts are the go

    Thanks for the heads-up, my bump stop nuts were only finger tight. I've replaced them with M8 nylocks.

    Hell, those are big! Mine are only held on with M5 nuts. I replaced with stainless nylocks, as I already had some lying around.

    Add me to the list of bash plate bolts missing, just one of four, and all three left were barely finger tight.
    I’m not seeing the bump stop bolts you speak of. Any clarification based on the pic above?

    I didn't understand that picture either. Invert the seat and under good light you will be able to make out a couple of nuts directly under the hump.

    Actually the nuts are in the photo. I got distracted by the teddy bear.

    Apologies, that's a typo, they are M5 using an 8mm socket. The bear is Louigi, a mascot my wife, Jane bought at Agostini's Guzzi dealership in Mandello. He's meant to be pointing at the fasteners concerned :blush:.....

    Regrettably, I don't have a V85, but appreciate this thread.

    Just installed a bash plate on my Stornello -- only the poseur in me really needed that :giggle: -- and am going back now for "a little dab'll do you" of loctite.

    Thanks. :clap:

    A few more to note. The left bar end weight/handguard bolt was loose on mine within the first 600 miles. No loctite on either side.

    We're doing the first service now at my shop, and two of the plug wire cover bolts (same as the V7 III/V9) were too tight and soft as butter, and the allens rounded out. Have some ready for those who DIY. Will post later on the fuel filter type, evap and SAS.

    A V85TT owner on the Moto Guzzi Club GB forum has also lost his front two sump guard bolts. When we visit the factory 6th to 8th September I'll look out for big bottles of Loctite on the production line :giggle:.....

    Hi Guys just picked up mine, 120km ride home at night in the rain from the shop, left hand guard bolt hanging out and headlights pointing at the ground (center adjustment bolt loose). Thanks for the heads up on other bolts I’m off to the loctite shop. Hoping the clutch beds in, it’s slipping over 4500rpm so I’ll take it easy and see how it goes. So bloody impressed with it so far, classy bike to ride, can’t stop smiling and going into the shed to “check” on it.
    Can’t wait for the full exhaust system and maps etc, sign me up!
