    For 1100/1150 models

    I read so much bollox on how to do this simple task.
    The pictures were taken with the oil drained during a service. But you don't need to drain the oil to replace the sight glass, just lean the bike over to the right and lean it against something, or have some support it.
    And another thing, the window isn't glass, it's plastic.
    So here it is in pictures, and it'll take you longer to read this than to do the job.

    Tools needed - old screw driver, hammer, seal puller or other hooked implement, 30mm socket and extention.
    You want a 30mm socket because it's the same diameter as the sight glass.

    Hit screwdriver into plastic face, not to hard, you just want to break it.

    Hook the seal puller, or other hooked implement into the edge of the sight glass .

    And lever out.

    Carefully insert the new unit with your fingers just so it stays in place, then use the 30mm socket as a drift, tap the socket extention with the hammer to fully locate the new glass

    Job done in two minutes if your slow.

    Excellent write up and pics. I'd vote to post this in a "How-To" section.

    Regards,

    Do the 1200's utilize a retaining ring? Do they have to be replaced as often due to leaking and/or falling out?

    Yes, they use a retaining ring. Even so, I carry a spare around.

    The part number for the oil sightglass itself is the same for the 1100 and 1200, though.

    Can't address replacement frequency. 38k miles on my 1200 and no sightglass issues.

    Good point. It seems to be less of an issue with the 1200 so far. But it is probably a function of age, miles, and no retaining clip that has the 1100/1150 ones fail at a higher rate.

    When breaking the plastic do you not run the risk of a piece droping into the engine?

    Look at picture three. Plus, as i said, your only breaking a section to enable you to get something hooked inside. How simple can it be. :cry

    How 'bout putting a screw into the plastic and then pulling it out. Very easy and has been done by several people.

    sometimes the dirt guys cover the sight glass with a thin layer of clear silicone so rocks will bounce off. smooth it out with an icecube and you can still see thru it pretty well.

    I got this idea from using a "Ding King" dent removal kit.

    Materials required:

    Hot glue gun
    bolt or screw with large head
    alcohol

    Engine cold:

    1. Clean sight glass and bolt head throughly with alcohol.

    2. Put a big blob of hot glue on the bolt head, apply to center of sight glass.
    Hold in place until set, let cool a few minutes.

    3. Pull out sight glass.

    4. Peel or pry hot glue from sight glass.

    Try heating a small nail, stabbing the plastic to make a melted hole, then run a small screw into the opening. This avoids anything falling into the engine (fragments from breaking plastic and/or shavings from drilling the hole). Use the screw to remove the defective sight-glass. Install new parts.
    Refill and enjoy the ride.

    You beat me to it! Was going to do a tech post on the change out on the sight glass on my 1100 pretty soon.

    Nice write up!

    I just drilled a small hole, then put a wood-screw into the center. I pulled it out with pliers. No need to break the plastic into pieces. Easy.

    Carefully clean the rim around the hole it goes into before putting the new one in. Your are right about using a big socket to put the new one back in. And, using the socket extension like you did helps hold it straight and gives you a place to tap that spreads the force evenly around.

    You don't need to break the plastic into pieces. All you need is plastic cracked to enable a seal puller to lever against. Just how easy is that to do. And you can do it at the side of the road if it decides to leak while on tour.
