    I am about to place an order with Ventura and I noticed that they have a headlight protector for the 640 Adv - sans pictures (!@#$%).

    I've seen the TT guard, but this Ventura one is new to me.

    Does anyone have said a protector? Thoughts? Pics they could post a link to email me at robert.maclellan@sympatico.ca?

    Might as well save on shipping charges if able to and get a guard for the wife's bike.

    Thanx.

    I think the Ventura headlight guard is simply a thick layer of 3M adhesive, I use the same thing on my 02 LC4 Adv., my headlight have to to suffer any damage to date, at 12000 miles.

    Any yellowing?

    The Venture 950 light guard, which I am ordering, is a polycarbonate item. Of course with the small, recessed, lights on the 640, fitting ploy disks would be difficult - the dualock fasteners would block too large a %'ntge of the lens area.

    I've got the stick-on covers. No yellowing after 1.5 years. Got 'em at Dual-Star. :thumb

    I've had the stick on ones on my wife's Subaru for two years. Other than some extremely fine scratches, they look exactly the same as they did the day I put them on.

    Good stuff, but not cheap. Cheap compared to headlights though.

    do a Google search on "3m headlight protector". I think it's called Scothcal. Can be bought from 100's of places. Pre-cut or in sheets.

    Dual-Star sells it as a kit pre-cut for the Adventure.

    Bought some at Dual Star. $13.95 plus some minor shipping amount. Cut to put right on the LC4 Adv (or other bike, they have a few). Review to follow.

    ps - Dual Star seems to stand behind their stuff. My failed mirror bracket got me a RA#, UPS shipping code (no charge), and a turn around of less than a week from when I shipped it back. :thumb :thumb

    I've got the dual-star guards also. A friend of mind did the Mex-Can ride with them - held up good, considering. They're not invincible though. A BIG rock got kicked into his headlight & cracked the glass - good thing is the guard has been holding the glass in place for over a year now - just a crack.

    Now, I hit a tree at 30-40 mph & I'm guessing no headlight guard could withstand that.

    I'm using Touratech's (www.touratech.de) headlight cover on my Adventure. Have seen that KTM-Sommer (www.ktm-sommer.de) has the same cover aswell.
    I'm very satisfied with the Touratech cover.

    Wassup AiStU, just a note, some people upgrade the Plexiglass in that setup. Should be pretty easy to get a nice thick piece and use the current one as a template. I think some found it a bit thin if you are around bigger rocks with other bikes. :thumb

    I think I'll go the 'glasses' route and upgrade the plexi to a little thicker Lexan.

    Remove the plexi original, stick it to a piece of lexan with some STRONG double-sided table.

    Cut the Lexan in the ROUGH shape of the original, then use a router with a bearing-equipped template bit and it will creat a perfect copy.

    Did it to make covers for our GS's - the problem with a home-grown 640 option is making good-looking mounting brackets

    Rather than make an exact copy I would suggest following the red lines shown on the pic. as the plastic is prone to snap across the white line area and therefore you would do best to have as much 'meat' in that area as you can.

    Note to all.

    The 3M stuff does not work to protect against rock hits. I know from experience. It will keep the glass from shattering and falling out, but the lamp was still toast underneath.

    Go for the lexan cover for sure.

    Just a word of warning to folks wanting to make their own covers - DO NOT use Acrylic, use LEXAN.

    Acrylic, while stiffer at a given thickness than Lexan is far more brittle and WILL crack around bolt holes as you tighten them -- and it will not take a rock hit well.

    Lexan is a tad more flexible, but is (at the right thickness) literally bulletproof and, while not really important here, has a higher softening temperature. It takes bolt holes, etc like a trooper.

    I've used Lexan for a multitude of uses, including using a 1/8" sheet to protect a painted door that our 160lb Irish Wolfhounds like to stand up on against and pound the snot out of when they want in. Makes great entertainment for the neighbours. :eek1

    Both, while abrasive, will machine like wood. However, if using a jig or scroll saw to cut it (vs.a bandsaw), have someone mist the area where the blade is cutting with a water bottle - AS YOU CUT.

    The small surface area of a jigsaw blade that does the actual cutting gets VERY hot as lexan/acrylic is very abrasive. The resulting heat, unless removed via a water mist, will cause the cuttings to fuse into little balls and clumps of plastic that will fuse the sides of the cuts back together behind the blade.

    A high-tooth-count bandsaw blade works wonderfully because the continous loop of blade has a chance to cool as you cut.

    Also lightly sand the edges of the cut lexan with some fine sandpaper (or an acrylic 'file' sold at HD, etc) to break the edges - they will be sharp.

    Has anyone made the entire thing out of plastic? It seems that with a little judiciously applied heat, you could bend the "earpieces" 90 degrees and be done. Any naysayers? Any advice? Let's hear it!
