    Consider the original TAT, Lakeview-Fort Bidwell-Denio-Fort Mcdermit-Battle Mountain-Eureka-Baker then continue.
    Keeps you more south
    Either way, have great, safe ride.

    Just an update on the shock knuckle issue.

    Just after the JBweld cured I was cleaning it up with a dyna-file/used scotchbrite belt, it went away pretty easily. Which told me this may not be the best solution.

    350 miles of wet sand and it's gone. It's hard to see but that's bare alunymoon.

    Here's my next test. I wanted something thin and relatively tough. I found a small sheet of 0.020" titanium that will be glued to the troubled area. I cut it to match my wear pattern with some surface above and below for gluing area.

    Here it is just hanging in place.

    Epoxy or JBweld? I suppose both will work just fine.



    Some of the things I've noticed that affect the wear.
    1. Wet riding. Hitting puddles or water repeatedly keeps loading the area with abrasives. If it's dry, just the opposite. This seems to be the biggy.
    2. Ride height. If you run more sag or heavy loads the inner fender does not contact the knuckle as much. Less sag, higher ride heights equals more wear.
    3. Shorter wheelbase/chain may cause the tire to rub a bit more in that area.

    I will also take a heat gun to the flap to tweak like was suggested earlier by ?

    I've got one more ride/test in a few weeks. After that my season is pretty much done except for the ice.

    Thanks for the update:

    '' 2. Ride height. If you run more sag or heavy loads the inner fender does not contact the knuckle as much. Less sag, higher ride heights equals more wear.''

    My 2018 450 Six Days was lowered 1.96'' front and rear and I have not seen any wear yet, plus no muddy sand stuff.

    Would an aftermarket mud flap made out of different material/compound reduce the abrasion on that point?

    I don't think so. As long as water carries the abrasives to that area it's gonna happen.

    edit: I need to proof read my brain ramblings before I hit send.:nod

    ummmm? I'm not sure I like where this is going.

    For the record I hate water and mud. It's so dirty. You should see me avoiding puddles and such.:rofl

    yah.. you never know what is lerking in that muddy water or how deep it is in the upper mid-west... Those streams I just did in CO and WY were so nice and clear you could see exactly what was in the water and the depth.

    stark difference

    I've searched around for some used OEM Take Off's, for foot pegs. To clarify it's for an 18' 500 EXC-F, does anyone have any pegs for sale?

    Thanks!

    Another rear shock/swing arm/mudflap update... after about 10 hrs of single track and 15 hrs loaded with camping gear ( and several power washings) the self adhesive 3M duolock seems to be doing the job.

    Did a video review of both the Cyclops LED as well as the Motominded Ultimate Pro on my 350EXC.

    TAT update. Yep - it's cold! Worse in a few days just in time for Colorado :(
    I really wanted to do agate Creek but fear it might be snowed in Thursday. Any locals have any thoughts?

    Bike is doing great. Had one issue where the rebound side fork just came apart inside after anda few days and caused a major thunk on rebound for big hits. I think the shop that I had change the springs didn't torque it back. When we took the the fork cover off the cartridge lifted right out with the spring, not even attached to the bottom. Yikes.

    I made my own route from Tahoe to eureka NV. Turns out satellite photos aren't good indicators that a road still exists or is passable. Who knew? From there follow the old TAT tracks that go through NV.

    Favorite riding so far was devil's racetrack or the narrow canyons outside Moab. Some sketch parts being solo though.

    Bike just blows me away. It does it all.

    Thanks for the tip. Quick trip to Walmart and I've got a Duo Lock patch in place and enough left over for my $2.98 investment to repeat the process 7 more times. Will be riding the Parashant & Gold Butte areas of SE NV/NW AZ later this Fall and will report back on patch wear.

    Saw an inmates comment a few pages back regarding his 500 wearing thru chain guides relatively quickly. Checked mine and was surprised to see its quite worn, ready for replacement at ~100 hrs (2800 miles).
    Kinda apples & oranges but my 690 with 12k miles shows little chain guide wear.
    Why the large apparent difference? I think the 500's chain sag is greater than the 690's and wonder if that's the explanation or if their OEM chain guides are that different in durability (they are different part#s). Or some other factor(s)...
