    Hey Guys
    After being the high bidder for a $50 GSPD skid plate for the last week, I was sniped at OEM cost.....:deal
    Well I can't whine too much, at least I made FF pay for it :lol3

    So, after loosing it I've decided to try and make my own. I happen to have a 3-4 foot 1/4" thick aluminum sign that I got to "dispose" of after putting up a new one. I'm hoping I can get some measurements to make my own.

    I also need to drill some holes in my Pod to mount a fairing. I really don't want to pay 8 bucks for the BMW template. Anyone have one to send? Or even better, a spare front pod they want to sell :deal

    you've got the coffin fairing, where'd you score that? They're hard to find.

    I think I've still got the template, I'll need to dig for it, plus I'd want it back.

    Twin headlight Earnie sells a very nice center stand guard, I had to put a small half round notch in mine to access the drain plug. His sump guard isn't good for a G/S, ask Jenna.

    I made this skid plate out of 1/8" aluminum, I traced from a GSPD plate, PM me if you want a copy of the outline.

    Mark, that is a beautiful repro of the stock PD plate :nod

    And you did it right/crucial by countersinking the mount screws-- if that countersinking is not done and the bolt heads are proud of the plate, a log crossing turns into a log hang-up, every damned time


    Raven, if you have grinding/maching tools and a big vise to use as a bending brake, get Mark's template and make your own. 1/4" alu is in the neighborhood of the 4mm stock plate. I've gotten free cast-off pieces of 4mm from the local welding shop-- made my centerstand skidplate from that

    My stock PD plate shows how sweet Mark's copy is :nod

    Thanks, it has worked very well. The 1/8" aluminum was a pain to bend, I cant imagine bending 1/4". I need to build the centerstand plate next and had something already cut out but I like yours better so I need to make another trip to the scrap yard. I also made a bigfoot for the side stand out of the same material.

    those big dumbass rectangles in my centerstand plate were necessary b/c the R80G/S centerstand had the tang-loops for the springs proud of the fwd edge of the stand-- just like all previous BMW road bikes. My plate had to have those holes to accommodate the springs in both extended and stowed configs.

    Your 100GS stand has the better design, where the springs are latched to tangs welded inside the stand geometry, so a center plate can be pretty much flush to the stand itself

    I will say this: a centerstand skid works if you do any log crossings regularly. Momentum and whatever front wheel loft you can get and the skid plates let you slide/bang over some impressive logs. Otherwise it's just bling to look at and make people think GS's are dirtbikes :lol3

    I tend to use my skip plate often, big rocks like to jump up at me, I have been lucky so far with no center-stand plate but I don't want to press my luck.

    The centerstand hangs lower than the sump on my G/S and it gets stuck on logs. It's only a 1/4" or so below the sump and it shouldn't be a problem, but make sure your bash guard is lower than that.

    +1 on Mark's bash guard. Looks waaaay better than the one I'll make!

    Stock G/S sump guard and twin headlight Earnie center stand, no unsightly hole in it for springs.

    still available if you PM me.

    3/16" thick. built using eMachineshop using Ghedo's plan, except i shaved a few mm from the back edge to reduce cost and i but 3 bends to round out the front angle a bit. eMachine shop makes recommendations to save cost thus the shaving at the rear.

    i mount it with the mcMaster carr 6mm male-female shock mounts and consider those expendable. they will shear under very hard hits. touratech uses the same mounts and they recommend carrying spares.

    oh, and make SURE to use a 90deg METRIC countersink, instead of 87deg sae. so the metric screws get the most surface area to pull on.

    ive never broken a screw or damaged the sump or sump threads, only torn the rubber mounts in half.

    Nice :D I have an outline coming that will serve me well in making my own. Now need a diagram for the center stand plate

    How did you guys that made your own get the countersunk bolt holes right? Did you press them with something?:ear

    Looking good by the way - I'm into making stuff that I can (& occasionally stuff I can't:D), adds to the experience of owning these fine beasts.

    I drilled mine with a countersink drill bit after I drilled the pilot hole. Mine was made with pretty much simple garage tools, nothing special.

    im not sure what you would call this, but i took a 6mm bolt and filed it to a center point on one end. x4

    then i installed these into the sump with the points sticking out.

    then i held my skidplate in place and hit the bottom with a hammer to make 4 tiny marks. i held the original skidplate overthose as a reality check.

    then i drilled a single pilot hole on one mark and did the metric countersink just a tiny bit at a time until it was exactly the same size as the screw head.

    then i removed the locating point for that hole. and installed the metric countersunk screw from the bottom .

    checked the location of the skidpan and hit with a hammer again to make a deeper mark.

    drill pilot, countersink, remount using 2 screws and repeat on the 3 hole.
    then remount using 3 screws and repeat for fourth hole.

    finally i installed the shockmounts and reinstalled the skidplate using blue loctite.

    (i actually did it once without blue locktite and lost a screw before i learned my lesson)

    The method I used to put the recesses in mine was to, after drilling the holes, position a 30mm socket under the upside of the plate and tap with a ball-pean hammer until I had about a 1/4" deep dimple. Then I turned it over and placed a piece of 3/4" barstock under the downside and tapped with the flat end of the hammer to flatten out the center of the recess to accept the bolthead and washer.

    For the rubber spacer, I took a piece of truck mudflap I'd found on the side of the road and using a 1 1/4" holesaw punched out four spacers.

    I like making my own stuff, too.
