California Scientific Windshield Installation Instructions

BMW F800GS / F650GS:

First adjust your clutch and brake levers. Your Calsci shield will interfere with the BMW hand guards at full steering lock unless they are adjusted correctly. Although this can only happen at parking lot speeds, it's still a nuisance. Loosen the bolt that holds the clutch lever to the handlebars. Sit on your bike with your normal riding posture. Extend your fingers on your left hand so that they are comfortably straight out, following the line of your hand and forearm. Rotate the clutch lever about the handlebars until it is just barely touching your fingers. Now tighten it up. Same thing for the brake lever.

Remove your stock windshield. There are two black plastic "L" shaped brackets connected to the fairing, remove these from the fairing. There will be two small brass square collar nuts and two screws that held these to the fairing, put these away, we won't be using them. Take two 5mm x 20mm screws, four steel washers, and two lock nuts, and put the L brackets back on the fairing. Don't tighten them all the way yet. Attach the two support buttresses to your windshield. Use four supplied 5mm x 20mm stainless steel screws with a SS washer on each. Put the screws through the windshield from the front on the outer two most holes. Put a rubber washer / spacer on each screw at the backside of the windshield. Place the support buttresses on the screws. The bent flange on each buttress goes towards the middle of the windshield, and the buttress angles downwards and outwards towards the bottom of the shield. Now place a SS washer on each screw on the backside of the flange, and place a SS nylock nut on each screw. Tighten all four screws. These should be tightened firmly, leaving no loose play in the buttresses, but not to the point where the rubber washers / spacers are significantly distorted.

Attach the Calsci windshield to your bike using four stock Torx screws in the remaining four holes. Now use the two remaining stock Torx screws to attach the support buttresses to the "L" brackets. You'll have to spin the "L" brackets a bit to get them to line up - that's why we removed the square brass collar nuts that didn't allow the "L" brackets to spin. Now tighten everything up. The screws should all be taught, not as tight as you can possibly manage - these are not motor mounts.

BMW F800S / F800ST:

Remove your stock windshield - this requires a T30 Torx driver. Place about 2" of the supplied foam tape on your instrument cluster to pad it from the windshield. Cut the remaining tape in half, and place half on each side of the center mounting screw hole. This foam is to seal the bottom edge of the windshield. Use the supplied philips screws to mount the new windshield. The metal washers go on the screw first, then the rubber washers go between the metal washers and the windshield.

BMW K1200GT:

Remove your stock windshield. Attach the new windshield using the stock hardware.

BMW R1150GS:

Remove your stock windshield - four Torx T35 screws at the sides. There are four Torx T10 screws on each side of the windshield holding the black plastic fittings onto the shield. Remove all eight screws and the four fittings. These pieces are marked internally "L" and "R". "R" means throttle side.

Now slide the windshield / front bracket combination into the bike. Place the four T30 screws through the buttresses and thread them into the fairing. Get all four adjustment screws partially in, then tighten all four.

BMW R1200GS:

Remove your stock windshield - two Torx T20 screws in the front, and two large adjustor knobs at the rear. Be careful with the hardware, there are lots of pieces want to fall out and get lost. We need all these parts. The black nylon covers snapped onto the stock windshield are held together with three snap prongs, visible from the inside of the windshield. Gently pry open the snap prongs with a pocket knife or pen, and the two pieces will fall off the windshield. These pieces are marked internally "L" and "R". "R" means throttle side. Keep everything in the correct order and on the correct side.

Attach the support buttresses to your windshield. Use the four supplied 5mm x 20mm stainless steel screws with a SS washer on each. Put the screws through the windshield from the front. Put a rubber washer / spacer on each screw at the backside of the windshield. Place the support buttresses on the screws. The bent flange on each buttress goes towards the middle of the windshield, and the buttress angles downwards and outwards towards the bottom of the shield. Now place a SS washer on each screw on the backside of the flange, and place a SS nylock nut on each screw. Tighten all four screws. These should be tightened firmly, leaving no loose play in the buttresses, but not to the point where the rubber washers / spacers are significantly distorted. Snap the round plastic rear mounts to the octagonal holes at the rear of the buttresses. The narrow portion goes forwards towards the shield. Slide the aluminum flanges into the round plastic mounts. Finally, bolt one of the lower front mounts to the windshield. The straight rod points in towards the center, and the sloped part angles upwards. Do not completely tighten the bolt, we need just a little free play for another minute.

Now slide the other front mount piece into the support bracket on the bike. Tip the windshield forwards and slide the windshield / front bracket combination into the other side of the front support. Now bolt the other front support to the windshield. Get everything lined up, and tighten both bolts. Rotate the windshield back until the support buttresses are aligned with the mounting slots on each side of the headlight. This windshield is designed to be used in the upper position, although it's ok for you to tilt it backwards. Place the two screws through the buttresses and thread them into the flange nuts. Get both adjustment screws partially in, then tighten both.

BMW R1200R:

Our windshield requires the BMW touring tall shield bracket (#71-60-7-699-573). It will not fit on the sport shield bracket (#46-63-7-697-210). Install the tall shield bracket according to BMW's instructions. Our shield bolts onto the BMW support brackets. Note: The curvature of our shield is different than the BMW shield. This is one reason why ours works better. However, the fit to the BMW support brackets is a bit strange.

BMW R1200RT:

Remove your stock windshield. Attach the new windshield using the stock hardware. Put the center two bolts in finger tight. Next get the upper and lower two bolts threaded. The Calsci windshield does not perfectly match the curvature of the mounting brackets, but it will form to the brackets in a few days. Now alternate between the top and bottom bolts, slowly tightening and warping the Calsci windshield into place. Don't over-tighten the bolts, these are not motor mounts.

Buell Ulysses:

Remove your stock windshield - it snaps on and off, no tools. Optionally remove the four rubber stock windshield mounts from your front fairing. Remove the top four screws on your front fairing piece. Place the Calsci windshield in place. Use the four supplied 1/4" nylon spacers and 1/8" rubber washers between the shield and the fairing. The spacers touch the bike, the washers go between the spacers and the shield. Use the supplied 1" screws and washers to hold the windshield in place. The washers go between the screw heads and the windshield.

Can Am BRP Spyder:

First adjust your clutch lever - the Calsci shield will interfere with your clutch at full steering lock unless it is adjusted correctly. Although this can only happen at parking lot speeds, it's still a nuisance. Loosen the two T30 Torx bolts that hold the clutch lever to the handlebars. Sit on your bike with your normal riding posture. Extend your fingers on your left hand so that they are comfortably straight out, following the line of your hand and forearm. Rotate the clutch lever about the handlebars until it is just barely touching your fingers. Now tighten it up. Remove your stock windshield, four T30 Torx bolts. Hold the Calsci windshield in place. Replace the four T30 Torx bolts. The Spyder is very sensitive to screw position, so this will be easiest if you get someone to hold the shield for you while you put in the screws. Don't tighten any screws until all four are in place.

Kawasaki Concours:

Remove your stock Kawasaki plastic windshield mounting screw covers - four 4mm allen screws. Keep track of left and right and up and down - the plastic covers fit in any configuration. Remove the windshield - two 5mm allen screws. Place your Calsci windshield on the six mounting lugs. Place the white nylon washers over the center two lugs, and replace the center 5mm allen screws. There's a rubber gasket on the stock windshield, move it to your Calsci shield. Replace the black plastic covers using the 4mm allen screws.

Kawasaki Ninja 650R:

Remove your stock windshield - four 4mm allen screws with white nylon washers. There are two black rubber gasket on the stock windshield between the windshield and the fairing - peel these off, we'll be reusing them. Mount your Calsci windshield using the Kawasaki rubber gaskets and four 4mm bolts with nylon washers. Be careful - it's easy to push the rubber well nuts into the fairing.

Kawasaki KLR:

Remove your stock Kawasaki windshield - it's held on with four screws and four well nuts. Remove the well nuts from the stock shield. A bit of spit as lubricant will help. Put the well nuts into your Calsci shield - again, a bit of spit will help. If you're having trouble with this, you can thread a screw into a well nut and use the screw to push it in. This will stretch the well nut and make it fit easier. Slide your Calsci windshield into place. This is a bit tricky, but if you take your time and don't force things it will slide in. Replace the screws - don't over tighten them. The longer screws are for the bottom holes. You may have to reach inside the shield and grab the well nuts to get the screws started. It helps to have a child or small woman handy to reach inside. You may optionally use black spray paint on the inside of the windshield - use several strips of 2" masking tape to protect the windshield. Mask off from the bottom of the vent to the top of the windshield. Lay the windshield down on some newspaper, and spray from behind with any brand and color of acrylic lacquer, your choice of gloss, semi-gloss, satin, or flat black. Allow the paint to dry. It will look fantastic from the front.

Kawasaki Versys:

Remove your stock Kawasaki windshield - it's held on with four screws and four cap nuts. Under your stock shield there are four rubber grommets that protect the shield from the metal mounting brackets. Leave those in place. There are three mounting positions for the shield, you may choose any of them. Bolt up your Calsci windshield. Swing your handlebars to full lock. If your mirrors hit the shield, loosen the mirrors where they attach to the handlebars. Adjust your mirror stalks so that they don't quite touch the windshield, then tighten them up. You'll have to adjust your mirrors when you get on the bike.

Honda ST1300:

Remove the windshield bolt covers. Remove the four 8mm bolts holding on the windshield. Keep the rubber gasket in its place. Place the Calsci windshield against the mounts, and use the stock hardware on the top two holes. The Calsci windshield does not perfectly match the curvature of the mounting brackets, but it will form to the brackets in a few days. Push the bottom of the windshield into place and use the stock hardware to warp the Calsci windshield into place. Don't over-tighten the bolts, these are not motor mounts.

Suzuki VStrom:

Remove your stock Suzuki plastic windshield mounting screw covers. We won't be re- using these. Remove the four mounting screws. Substitute the supplied 25mm screws for the stock screws, reusing the stock collar washers. Optionally place the supplied rubber bumpers on your fairing on the outside upper corners to protect your paint from the shield. Optionally use the supplied black ABS oval mounting covers to hide your mounting hardware.

Triumph Tiger:

Remove your stock Triumph windshield - six nylon philips screws. Replace it with your Calsci windshield. Be careful - it's easy to push the rubber well nuts into the fairing, and then it's very difficult to find them. Optionally (highly recommended) use the supplied stainless steel mounting screws. Your Calsci windshield is a large sport-touring screen, and I consider mounting it on a 135mph+ motorcycle with nylon screws to be speculative.

Yamaha FJR1300:

2006+: There are two allen head screws behind the windshield, on the bottom, in the middle, facing down. Remove these. The plastic W-shaped cover now snaps up and comes off. Seven philips screws to remove the stock windshield. Reverse to install your Calsci shield. Optionally use the nine supplied stainless steel screws to replace the seven windshield screws and the two allen bolts.
2002-2005: Seven philips screws to remove the stock windshield. Reverse to install your Calsci shield.

Yahama FZ1:

2006+: Remove your stock shield. Install your Calsci shield, optionally using the supplied stainless steel screws.
2002 - 2005: Six philips screws to remove the stock windshield. Reverse to install your Calsci shield.

Yahama FZ6:

2007+: Remove your stock shield. Install your Calsci shield, using the supplied stainless steel screws. You will need to push the windshield into place a bit for each screw - this is normal. The top two screws require that you maintain pressure on the shield holding it against the fairing until the screws are a bit taught.
