    exhaust clamp fail

    Off side exhaust clamp completely rusted through.

    Honda dealer prices look to be 25.00 each for the clamp and securing bolt, eBay search got me 2 MIKALOR 40-43 mm W2 clamps for 4.15 delivered. Perfect fit for the Mk I and the Mikalor clamp comes with a hinged gate that enables it to be fitted over the existing pipe joint without the need to dismantle the pipe.

    Might be a timely reminder to check yours.

    That's exactly how I came across mine, not that I'm one for cleaning I was just wiping it down with a dampened rag.

    Either type of clamp will probably do. I prefer the Mikalor clamps over the 'U' bolt type Halfords offer because the 20 mm wide band has a greater area of contact, they're easier to fit with the gated hinge and a single 10 mm headed bolt and look neater, not that they're that visible once fitted.

    Horses for courses.

    The u clamps work better and can be tightened up stronger,  less than 2.00 each will last longer than the ones you like.

    +1 for the Mikalor clamps, Art. Look great & last for donkeys. If you get the W4 version of the clamps, the bolt and housing is also stainless steel  :028: (on the W2 version the bolt is just zinc plated).

    Good call Shad, a little more research reveals...

    The W2 Mikalor clamps are 430 grade stainless steel, with a zinc plated high tensile bolt/barrel nut.

    The W4 Mikalor clamps are 304 grade stainless steel, with a 302 grade stainless steel high tensile bolt/barrel nut.

    The 304 grade stainless steel appears to offer a better resistance to corrosion over the 430. If I did it again I'd probably go for the Mikalor W4 clamp but the jobs done now. I'm expecting the W2 Mikalor clamps to outlast the Honda ones, they certainly look to be a better piece of kit, time will tell.

    Thanks for reminding me - mine fell apart during centre-stand fitting procedure - replaced it with a standard jubilee clamp which was only meant to be a temporary fix obviously...

    For what it's worth i've just done mine with the mikalor clamps, old ones falling to bits after 17 years but soaked them with ACF50 2 weeks ago when i ordered the new ones and they undid with nothing more than a few squeaks, new ones went on just as easily, as previously reported slip them over the narrower part of the pipe initially and then slide them forward, i didn't need to tap anything, just do it with the bolt as loose as possible.
    No idea what torque to use on the bolts and couldn't find anything in the haynes so will watch for leaks on next few runs.
