    so....do I stick with what I've bought or order the ones with the shoulder?

    Bike's done 23k. So the state of the headers surprised me. I do ride in winter in salty conditions but not often and not far

    Have since extended the stubby front mudguard as that probably exacerbated the problem

    For me, I'd get the OE studs & copper slip them & the nuts.

    Mine is a '14, done 27k miles, headers in quite good condition, not used if salt is down. I spent a winter in Glasgow, no way I'd be on a bike. I came home one w/e with 6" of snow on roof of car, still there when I got home, to the amusement of all the neighbours, who hadn't had any.

    I had a front fender extender fitted from new, so that probably helped save mine.

    When Triumph fired up again in early 90's they recommended to spray the exhausts with Motorex 645, now called Moto Protect & shine, I've stuck with using that. Spray the whole bike with it in winter.

    the stud shoulder does not pass through the manifold mounting hole

    will look into the motorex stuff

    Order OE from Fowlers & get them next day. Keep it simple.

    No - that's far to sensible. I've succeeded in making this into more of a palaver than really necessary already

    (tbh - I couldn't find the part on the fowlers fiche for my bike  :027: )

    the shoulderless studs arrived so will use those to get me back on the road

    ...and all back together



    new coolant while I was at it. The old stuff was a bit minging

    Took it for a quick spin to get and remaining air out of the cooling system and generally check nothing falls off. Intriugingly it seems to pick up more smoothly rather than the snatchy low rev throttle openings I'm used to. I wonder if the hole in the exhaust made the O2 sensor give out some bizarre readings that would change the fueling

    on a sad note the lovely popping and burbling of the holey old exhaust on the overrun is now gone

     :152: looks good  leighz.
    What did you replace the old headers with?
    New aftermarket ones or a good used set?
     :031:
    Yam RD125 DX, Kwak GPZ305, Honda CB400T, 1983 Kwak GT550, Suzuki GSF650 Bandit, Tiger 1050SE, 2019 Tiger Sport .... got there in the end.

    I just got my old ones welded up by a local exhaust guy. Replacements are rare on ebay and expensive (eye watering in fact - 750!!!) if you buy oem - assuming they're even available. Lextek make a copy without the balancer pipes and catalytic converter for a much more reasonable 300 ish - I'll probably buy some of these if my repaired ones don't work out

    The stuff of nightmares, that.   750 - I wonder if it is so much because it includes a new cat?

    Did he weld a plate over the crack or just run a bead of weld along it?
