California Scientific Windshield Installation Instructions

BMW G650GS 2011+:

First adjust your clutch and brake levers. Your Calsci shield will interfere with the BMW levers 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 screws 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. Same thing for the front brake lever.

Now adjust your mirrors. Move the mirror so that it is in the center of the adjustment range on the end of the mirror stalk. Now loosen up the mirror stalk at the handlebars and turn the stalk until the mirror is pointing in the right direction. If your mirror stalks are turned forwards and the mirrors turned back to compensate, the mirrors will hit the screen.

Remove your stock windshield - this requires a T30 Torx driver. Move the four aluminum spacers and four rubber grommets from your stock shield to your Calsci shield. Mount the Calsci shield using the stock screws. As soon as the screws resist firmly, they're tight.

BMW G650GS 2005 to 2010:

Remove your stock windshield - this requires a T30 Torx driver. Slide the aluminum spacers into the four rubber grommets. Install the upper two mounting screws first. On the top two holes, use the included 30mm screws. You have a 1/4" spacer and a 3/8" spacer. The longer spacer goes on the right (throttle) side, the shorter spacer goes on the left (clutch) side of the bike. The metal washers go between the aluminum and plastic spacers. Use the included 25mm screws on the bottom two holes to attach your new windshield. Place the 1/8" nylon spacers between the shield and the fairing.

BMW F650GS 2001 to 2004:

Remove your stock windshield. Slide the aluminum spacers into the three rubber grommets. Install the upper two mounting screws first. On the top two holes, use the included 40mm screws, with a small washers on the outside, and a large washer between the windshield and the BMW U shaped mounting bracket. Use the included 25mm screw on the bottom hole to attach your new windshield.

BMW F700GS

Remove your stock shield, four torx screws. Set that all on a shelf, we won't be using any of it. Insert the supplied rubber grommets into the larger holes in the windshield. Put a 3/8" aluminum spacer into each grommet. Place a translucent white cap holder on each screw head. Hold the windshield in place, and attach the upper 20mm screws loosely. Put the two 25mm screws through the grommets and attach them loosely. Now tighten all four screws to 4 ft-lbs - as soon as they resist, you're done. Pop a black screw cover over each screw head.

BMW F800GS / F650GS:

First adjust your clutch and brake levers. 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 front brake lever.

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.

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 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. Now tighten everything up. Optionally remove the two lower Torx screws from the front of the windshield. You may now use the additional two mounting holes in the support buttresses to change the angle of your windshield.

BMW F800S / F800ST:

Remove your stock windshield - this requires a T30 Torx driver. Place supplied foam tape on your instrument cluster to pad it from 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. These should be tightened firmly, but not to the point where the rubber washers are significantly distorted.

Remove your stock windshield, four Torx screws and two plastic covers. Attach the new windshield using the stock screws and the stock plastic covers.

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 2004-2012:

Remove your stock windshield - two Torx T20 screws in the front, and two large adjuster 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 R1200GS 2013:

Raise your shield to the highest setting. Remove the black plastic wind deflectors and the clear fly shield from behind the lower edge of your stock shield - four T25 torx screws. Remove your stock shield using the supplied Torx T25 key to take off the four torx screws holding it on. The four screws are facing backwards. Put your Calsci shield on using the stock mounting hardware. Optionally attach your supplied headlight protector using the double-stick velcro. Line it up carefully, you only get one shot.

BMW R1200R:

Our windshield requires the BMW touring tall shield bracket (#71-60-7-699-573) or (#77-33-7-714-440). 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. Optionally use Bales Tech spacer to tip the windshield back a bit. Some people have reported that they prefer the windshield like this. 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 R1150R:

Our windshield requires the BMW touring tall shield bracket (#71-60-7-685-197). 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 R1150RT:

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

BMW R1200RT:

The RT windshield has to curve to form to the brackets, which takes a day or two. It's important during this time that the windshield be at about 50 degrees or above, or it will crack. If it's going to get cold at night wait until it warms up a bit before mounting it.

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. Depending on the year of your bike, it either snaps off or you have to remove the front fairing piece to get to the nuts inside. 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 ¼" nylon spacers between the shield and the fairing. Use the supplied 1¼" screws and washers to hold the windshield in place. The washers go between the screw heads and the windshield. Two aluminum spacers go into each rubber grommet, then the screws through the spacers. Don't over-tighten the screws. Use a bit of loctite instead.

Can Am BRP Spyder RS:

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.

Can Am BRP Spyder RT:

Start your Spyder and raise the windshield to the highest position. Turn off the Spyder. Remove the chrome covers on top of your stock windshield, two T30 Torx bolts at the back of the windshield.

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.

Remove your stock shield. Install your Calsci shield, using the stock hardware. We recommend the lowest setting to start.
