    My 2015 Thunderbird Storm uses a few of these bolts on the throttle body. The Storm is in the dealer and they have found that this bolt is not available separately from the entire throttle body assembly. If anyone has one (and it might be found on other models as well) I'd love to hear from you!
    Thanks!

    @Walter Drane Why can't they just replace it with a hex bolt and washer.

    Yup, I agree! They seem to want to want only the factory style but if I can't find them one then that will be my Plan B.

    So if you/they can't find one they want to sell you a new throttle body assembly? There's nothing special about that bolt so stick a hex bolt in. Why not go stainless steel at the same time?

    They just found that they were not able to get the bolt separately from the factory source. Good idea about going stainless!

    That really stinks and is a poor show on Triumphs behalf!
    Buy a new throttle body and get a 50p bolt included.... jeez!

    I personally don't see anything special about the one in your photo @Walter Drane

    I agree, replace with a stainless hex head or an allen head, BTW whats wrong with the original bolt? Broken, missing or?

    Good question! Ok here's the story... This bike was purchased in 2018 as a leftover 2015. When the dealership (I believe the same one I am now working with) signed the title over the bike had 198 miles on it. The original owner rode it a few times and decided it was a little big for her. She made her 5 years of payments on it and sold it to me about 6 months ago with 220 miles on it. So she put 22 miles on it. She started it regularly but did not keep enough gas in it and the tank began to rust. She took the bike to a friend 'mechanic', who removed the throttle body, throttle cables, and then said he couldn't deal with it - but wanted $800 for his trouble. She paid him and then sold me the bike with the throttle bodies in a box mixed with fasteners and other parts from this bike and a BMW. I sorted out the parts as best I could, cleaned and de-rusted the tank, and put the throttle bodies back on. The bike then ran ok, until I tried to 'optimize' the mapping by using the procedure in the workshop manual to force a remap to current climate conditions. The bike then ran poorly, and then would not start again. I poked around but could not figure out what was going on, and so took it to the dealer.
    The dealer said that the fuel pump had failed (although I could hear it running each time I turned on the key - but maybe it was not pumping enough), and that there were things messed up inside the tank. They sorted that out and put on a new fuel pump ($850), but then found that a bolt was missing from one of the throttle bodies. It must have been something I did not notice, because both sides looked the same when I re-installed them, but all I had to work with were the parts in the box. And the 'mechanic' friend was not super-meticulous as he managed to lose the pillion seat. So tomorrow I'm taking the morning off to drive the few hours north to see if I can take the bolt and find a replacement that will work. I'm sure the dealer would do this for me, but I would rather save their rates for more meaningful work. The bike still looks showroom new, and I'm just trying to get it back on track.

    I would just take the bolt to a fastener supplier, any good one will have a suitable bolt in stock and charge you pennies.
    Easy for me in Birmingham UK , plenty about.

    So being in America @Walter Drane, all you need is a bolt that is 33/132ths NHC (Never Heard of it Coarse) by 1, 61/64ths" and a bit :rolleyes:
    :joy::neutral:

    Alternatively it's probably a fairly straighforward "M5 x 50" at a guess or possibly M6, hard to tell off a photo.

    This is a routine 304 stainless steel M5 x 50 cap head (correct term for an allen key head bolt) I have in my workshop.

    Swing by as you say and you can have a few ;)

    Yes, I was able to find M5-.80 x 50 bolts that did the trick.

    Glad you got it back together, that's great looking bike!! I like it so much that I bought a 2013 T Birdstorm new in 2013, same color, I've added Triumph saddle bags( panniers ) a passenger back rest small wind screen and a couple years ago a Mustang " touring " seat. I've put just over 27K miles on it. Great bike!!

    I always have a few of those in various sizes lying around the workshop. Recently bought some M12 x 1.5 x 50mm 12.9 rated bolts to mount the recovery points on the SUV.

    Thanks! Yes, it's a great bike and feels great on the road. Even though I've always been a Triumph fan, it was not on my radar until a relative mentioned that they owned and loved one, so I checked them out just to see what he was talking about and found this one.

    Jap bikes use JIS cross head screws and bolts which are not quite the same as Phillips heads which is the usual reason they get chewed up if they're tight and you're using a Phillips screwdriver. Not sure what Triumph uses TBH.
