Xj550 master cylinder question

I'm not sure how to remove the wired sensor from my master cylinder. How is it locked on? Also a separate question, does the 81 xj550 seca run some type of chain glide to protect the swing arm from rubbing metal at the pivot point. Mine seems to drag right across it. I raised the back 1.5" after installing new shocks so that may be why it's so close, so not sure what I should do. There is no noise from it but it's so close I am pretty sure it's rubbing the the pivot area.

 

here are pictures as related to the questions. Hoping someone can hook me up w a photo of how this chain area should look if mine was modified.

 

I asked the exact same question a year ago. You have to go underneath the switch (like, get on your back), and you'll see that on the underside of that switch, there's a place to push in a flathead to unlock the switch and allow it to slide out.

 

Thanks for the response! Is it like a C clip that you pry off?

Thanks for that link! So easy once you know the trick!

 

There is no guide between the chain and the swingarm. You shouldn't have a problem as long as you keep the chain properly adjusted. Your shocks are definitely the reason why the chain is so close. When you sit on the bike and compress the shocks, you will probably notice the chain raise up a little.

 

Let's start with a little LUBRICATION on that chain.

Or better yet, since it's that rusty there's a good chance the pins have had their bearing surfaces compromised; so it would be prudent to replace it (and the sprockets) NOW before it fails.

 

thanks for the feedback. In the photo the chain does look super rusty. I may change it out to be safe. It actually has a red tint to it from the greasy lube the previous owner used. I need to clean off all that and check for rust to be sure. I'll get a better photo of it too.
