    I had drilled the swinging arm of my '11 990 Adventure Dakar when it was new so I wasn't sure if it really did any good or not . I sold that and picked up '10 990 SM-T recently that had 17000 on the clock. I noticed that the swinging arm was not drilled so I drilled both sides. I was amazed by the amount of water that drained out.

    It’s pretty amazing just how much water can get in the swingarm reservoir.

    If it was not drilled the chain adjuster bolts are probly trashed , I bought a SE a few years ago and the po had not drilled the drains and had also put zipti axle blocks on it . That was a major pia , close to 8 hours . I ended up stripping the threads trying to get the pos aftermarket crap out and helicoiling new threads . Replaced the blocks back to original and lots of antisize . At least it was correct when I sold it .

    I was lucky. The PO used anti seize when installing the axle adjuster bolts.

    I pull the bolts and grease them with moly-grease at every new chain/sprockets. Also, several times when I change a tire.

    I had the bolts seize on my 08 990 around 2015. I drilled drain holes as advised from fellows on Advrider and applied antisieze after a struggle to remove the stock bolts. Changed out the tires recently and made sure I screwed in and out the bolts in question. All is good:) Thanks fellows it is good to have camaraderie keeping the 990 on the road.

    On the TAT, crossing a desert Playa, Utah Nevada border... Yep had to remove the fender to continue.
