That's amazing. Mine didn't have anywhere near that much. I think I'll show this to my dealer. They'd be interested in this.
I don't know for sure. I can see easily where they can be a leak point, but haven't examined every square inch of the swing arm. I'm leaving things over for a few days in the dry weather, planning to WD40 it as well, to see if things dry out thoroughly before sealing everything up. And then checking after water to see if things stay sealed. Or, I'm also tempted, frankly, to leave the holes I've drilled alone if I don't think I can reasonably seal it all up completely. With that much water in there I swear my suspension felt more lively on my commute to work. Overall I *think* there was two soda cans worth of water that drained out!
When I have time check on my bike but I think I will work 'in this way. I will take away the pieces of rubber,'ll give you two threads in the holes that hold the rubber protector spray on the swingarm. After that we avviterò two screws in steel by applying the hydraulic hemp thread or better yet, tape nylon plumber's always special.
Not sure if I missed this elsewhere in the thread, but underneath the swing arm cross-member (below the mudflap) there are two open holes. I'm guessing this is one place where water is finding it's way into some swing arms... especially if it gets submerged. See photo...
What the hell, did you have a hose hooked up to the other end?!? That's crazy. I guess I need to take this more seriously. I've had a lot of fun in the water over the summer. Uh oh.
Those holes seem to be made to let out the water. You say that instead it is from them that comes in? and then ends up filling the arms of the swingarm? If you decide to access any plug for the water need to be sure it does not come anywhere otherwise you risk that remains with you forever. Perhaps then it is better to make two fine holes as you can see in the video, in the lower part so that all the water that enters can get out. Whether for rainwater to dive when you go into a ford of a river.
I don't have these holes on my bike. For what it's worth…. I drilled small weep holes in my swingarm a while ago and used silicone adhesive under the mudflap. I also used big globs of silicone when refitting the mudflap plastic press-studs (or whatever they are called) & sealed my small weep holes with silicone too. After the swingarm being submerged a few times over winter I decided to check for water again recently. It was dry inside - all good. So I've sprayed the inside with another good dose of fish oil & look forward to checking it again after next years winter fun.
Just drilled some holes in my swing arm. 1250km never been through any deep water, just washed the bike a few times. Got about half a cup of water out of the left side, none from the right.
Wow, that's messed up! Looks like the swing arm can be used as a fuel cell!! Imagine how this effects the handling of the bike. Unreal...
i watched the video then drilled my own drain holes. i could not believe how much water came out. i was thinking of filling the holes with "great stuff" foam gap filler any thoughts?
There are alreaedy holes in the swingarm? And you still drill yours? Isnt it enough to move the bike on a ramp? At least to get rid of the water what is already inside.. regards
What holes? There's where the water appears to enter the flap, but unless you have a hoist to turn the bike upside down--water's not coming out. There are also the holes that the chain tension adjustment bolts go into, but they seem to be water tight unless you remove them completely and only dribble sporadically if loosened. They're inconvenient to say the least. I drilled small holes where the swingarm drains 100%...all the time...on a level surface....at the lowpoint where water settles. If there are some other holes that do the same thing I'd love a picture and/or link.
