    Thanks for the info Rob, and thanks for your prompt and clear email coms with me on the clonk topic.

    Top man!

    I agree. Its nice to have someone who knows what’s going on chime in. Considering hardly any dealers close by to ask. Thanks Rob.

    Pretty ballsy move cutting your mudguard like that. I'm not a CF expert, but did you have to seal the cut edge to prevent fraying of the fibers?

    Just sanded it smooth, quite a straightforward job really, only took 5 mins and you can’t tell it’s any different.

    Of course, now my cooler is at the correct angle, I can see there’s no need to have cut it.

    What is it they say, measure twice, cut once...!

    Straight cut end to mudguard is a custom mod and looks quite rakish.
    You may have started a trend.

    I’ve always been something of a trend setter...

    I've just finished mine, I too shortened the hoses. I think I have gained another 10-15mm clearance (fork travel) which might be ok for me and my style of riding BUT I think it would still hit mudguard on full fork travel AND I have no confidence that the angle of my dangle will stay put 'cos those rubber mounts are just too flexible.

    I'm going to come up with an additional support bracket, I like to cross my t's and dot my i's

    Unless it’s just a strange angle at which you’ve taken the picture, that does still look like there is not enough clearence for the avalaible fork travel to me...

    It's a strange photo angle. I estimated that I was about one length of my trusty allen wrench -8mm clearance BEFORE adjustment and about one length of the wrench + 5mm clearance AFTER. When I put my allen wrench against the fork sliders the 'o' ring on the slider is about one length of my allen wrench +5mm down. So I deduce that to date the furthest my forks have compressed is one allen wrench +5mm so I should be ok :)

    BUT I would still like to get that cooler closer in to the frame rails by a degree, maybe two.

    Hey guys,

    Just read this (12 month) old thread, killing a bit of time you know. Went straight to the garage as you do and I also have a clear witness mark on the rear of the front fender, where the oil cooler has been contacting it. No surprise there having read the thread.

    Do we agree that the ‘brains trust’ has solved this issue - shortening the hoses? Or have others gone on to produce alternate brackets/solutions? Did Norton offer up any solution other than cable tie the cooler rearwards?

    Long Live Norton

    Thanks.

    Steve

    Shortening the hoses worked for me (see post 20).

    Heard talk of a factory mod, but ain’t seen nuthin’ yet...

    Shortening hoses helped but not 100% so went with a home made cover/bracket which I could then cable tie back to the frame. I had forgotten all about it since installing so it must be working :)

    Thanks guys, appreciate the feedback.

    Not sure I’ve got the skills for the rolls Royce solution MxMartin, but I can certainly shorten the hoses.

    Thanks again.

    If you look at Mark (mx) frame brackets you’ll see that they are unfortunately at an angle which greatly exacerbates he issue. Hence his solution.

    If your brackets are similar, you may find that hose shortening is not enough. However, if your brackets are at right angles to the frame tubes (as mine are) you should find that careful shortening and cable tying is perfectly sufficient.

    The factory shortened hoses did not work for me so I have a couple of thin long cable ties round the ends of the cooler/ frame. Mine is black so virtually invisible. One more on the list of 'must get round to engineering that properly' jobs......

    I did think about 'encouraging' the brackets to bend down a little but they are thick steel and would need a good whack with a heavy hammer..... err I mean finding a tool for the job ;).... but I would need to remove the front end to get a good swing on it .... err I mean for 'the appropriate tool to get access' :)

    The factory sorted mine on the first service and have had no clunking since.

    Can we think about the reason for the rubber mount? Is it to prevent vibration cracking the mounts or to allow some flex from the pipes pushing it out of line - or both? To my mind the best solution is a guide to hold the pipes so they don't push it out of line.

    Interesting, maybe I missed it but I just noticed you have a stone screen in front of your oil cooler. Is that factory?

    Home made. My cooler had all sorts of critters between the fins from one Summer's use, some of them hit hard enough to distort the cooling fins.... so I cleaned, straightened the bent over fins (they are so, so, delicate) and added the fly swat :)
