mudsling hitting tyre's Avon Trail riders

[steele01]

Hi everyone just took my mudsling off after hearing a bit of noise noticed the mudsling was catching the tyres ever so slightly

If you aren't using a mudsling what do you use to stop your legs getting full of mud,

on a gsa 1200 TE

Cheers,

Had the same problem with my new Metzeler Roadtech 01's, took the mudsling off, went to Italy, came back and fitted it again and doesn't touch the tyres any more.

Fitted Trail riders on Friday - had same problem - well kind of.

Refitted rear wheel and while on centre stand, rotated rear wheel and it rubbed.

I took off the mudsling and re fitted - to make sure it was as far away from tyre as possible.

It still rubbed.

Then I thought with the droop on the rear suspension on the centre stand it may not make contact once both wheels were grounded and bike weight added.

This seemed to solve problem, although as I pushed backwards out of garage, stock patch on tyre where label was picked up a large piece of gravel and wedged it between the tyre and mudsling.

I removed the stone and all seemed well. Out for a thirty mile warm up with a stop part way - looks to be no mudsling rubbing - difficult to see as it is very close , but checking temperature of mudsling where tyre would make contact - no sign of extra temperature from rubbing.

To me looks like Mudsling did not leave much of a gap rather than tyre being oversized.

Loving the new tyres so far - quite different than Anakees IMO, used to have a preference of Conti's - but so far the Trail Riders seem promising.

Done another 40 miles on them today and they do seem to be developing over time - although from reading other riders reports this seems to be normal.

Heidenhau on mine has worn a 2 cm diameter hole through my mudslinger.

New Heidenhau put on last week still rubbing very slightly, not much room for movement so guess hole will get a little bigger, at least it's not corroding like the engine did !

This was the helpful reply I got from the manufacturers when I told them about my Scorpion Trail II rubbing the Mudsling. I was alos sent two documents saying a similar thing to the solutions below:

Clearances between the tyre and swingarm on the GS LC are much less than on previous
models, so a good fit with a MudSling depends on the profile and diameter of the tyre used. Standard issue Tourance Next and Michelin Anakee fit properly with the MudSling_LC. We have not tested the Pirelli. Aggressive knobblies, like Mitas and Kenda do not fit.

Apart from tyre, we have also found considerable differences in assembly tolerances from
bike to bike which can affect the position of the large underseat plastic moulded liner. That large part is the MudSling's primary locator.

Here is an example reported to me that proved assembly differences among bikes to be true:
Two friends each bought a Mudsling GS_LC at the same time for their same year GSs. The
MudSling fit perfectly on GS #1 with sufficient clearace. The MudSling on GS #2 made contact
with the swingarm. I asked the guys to swap MudSlings to determine if the variable was the
bike or the part. When they were swapped, the MudSling that fit properly on GS #1, did NOT fit
GS #2. Conversly, the MudSling that did not fit on GS #2, DID fit properly on GS #1.

To compensate for this possibility, there are two solutions to try to gain 3~5mm between the tyre and MudSling. Please refer to the two attached PDF files:

Possible Solution #1
1. On the left side of the bike remove the rear most zip tie from the MudSling. When you push down on the mounting flange, separating the flange from the frame tube, the bottom of the MudSling flexes closer to the swingarm. This uses the forward zip tie location as a fulcrum point
to flex the bottom of the MS forward away from the tyre.

2. Cut a 3mm rubber strip from rubber shim stock that is 6~8mm wide and 35~40mm long.
Place it in between the flange that you have pushed down and the frame tube. Then, install a
new zip-tie.

3. On the right side of the bike the flange shape is different and not flexible. You may not need
to do anything on this side. If you still need more clearance, remove the rearmost zip tie and
place a 1~2 mm shim between the flange and frame. That will net 1~2 more mm.

Possible Solution #2
1. Remove the seat to reveal two tabs which support the inner fender liner secured to the top
of the frame rails.
2. Remove the two screws securing the tabs with a T25 Torx driver.
4. Find a 3~4 mm thick rubber washer 20mm in diameter, or cut it out of flat rubber stock
and insert the rubber shims under the plastic tabs and re-tighten the screws.

These are options to try and I hope one of them works for you. Let me know how it goes.

Damn. Just as I've asked my dealer to fit the Avons to my new bike.

Is it rubbing on road, or just offroad?

I might have to rethink the tyres now.

 

[tanneman]

Thanks for that. A helpfull post in the LC section.

Hi everyone It was on road to, really gouged the mudsling out left side only Ill put some pictures up later might have been the way the previous owner fitted it, going to have a look at re fitting it later firstly though ride out today to decide wether to fall back in love with it again lol.

Cracking post that Moose I shall give that a try and report back, tbh only personal this but I'd sooner loose the mudsling than the Avons utterly impressed with them in every way

Keep us posted, as I'd rather have the mudsling, as the rear swingarm gets peppered by stones without one.

Fit a Puig hugger, get rid of the spade and fit a number plate splash guard........... the jobs oxo!

If there's not enough clearance with a mudsling, I'd be amazed if a hugger would have more clearance!

And a hugger on a GSA just ain't right!

Hi Friends. Not sure if this is helpful. I ride a 2012 R1200R with a Mudsling. It was catching my tyre and since I put a new one on, the catching has got worse. Took the Mudsling off, and refitted, but just the same. So drilled two one-eighth inch holes side by side to create a slot on one side, and then the same on the other. Pushed a plastic tie through both holes and then around the frame, slightly to the front of the slots. Pulled tight, and hey presto, quarter inch gap now between the Mudsling and the tyre. Any help? RobA.

Did either of these work?

 

[Moose]

Did either of these work?

Yes - I used the second solution. Quite an effort is needed to lift the inner 'fender' and I used nylon washers and bought some longer bolts.
But no rubbing on either the tyre or swinging arm.
