WINDSCREENS
High Impact Handlebar Fairing
This windscreen is made from polycarbonate which is exceptionally strong. Unlike perspex it does not break easily and we have built up a strong customer base amongst despatch riders.
The screen fits most bikes with tubular handlebars. Also fits
Dnepr, ETZ251, CX500, and also bikes with cast bars like GT Kawasaki,
XBR, NTV600, and others. Ring for fitting details.
* Made from supertough polycarbonate which has up to 30 times
the impact strength of perspex.
* Fits all bikes with tubular handlebars and Kawasaki GT models.
* Excellent weather protection for the upper legs, body, hands,
arms and head.
* Stainless steel nuts, bolts, screws and washers.
* Plastic coated lower brackets. Chrome plated clamps.
* Low weight and easy to fit on rectangular or round headlight
bikes.
* Feel and manoeuvreability of bike unaffected.
* Does not affect steering lock.
* Standard indicators and mirrors retained.
* Stylish angular design.
* Once fitted can be removed or replaced in 5 minutes.
This windscreen has been designed to give excellent protection
with low weight and reasonable size.
Most windscreens are made from perspex type materials which are
brittle, especially when they are subjected to low temperatures.
We make our windscreens from polycarbonate. The same material
used in bulletproof windows, safety unbreakable windows, aircraft
windows and space helmet visors. Applications where its strength
and temperature resistance are extremely important.
We use polycarbonate because it is extremely tough, difficult
to crack or break, and is not affected by freezing weather.
Other manufacturers steer clear of polycarbonate because it is
much more expensive than perspex and it is more difficult to mould.
We have built up nearly 20 years experience with this material
so we can produce a quality product at an affordable price.
Chris Dell, Motor Cycle News:
"With ears big enough to protect hands with most handlebar
shapes.....Polycarbonate is strong and difficult to crack...acrylic
is more brittle, if you crash or catch a flying stone it may break......Buy
John Morgans if you want maximum protection and reasonable cost."
Motor Cycle News 9/12/92:
"Best weather protection bar none........and is great value."
Motor Cycle Sport August 1994:
"At the NEC screens from Givi, Rickman, and Tripoint were
everywhere, but the best value seemed to be the Morgan....It works
- and works well. The degree of protection it offers is remarkable
and the bike seems no more affected by sidewinds now than it did
before.... Overall I'm delighted with this Morgan screen."

Step 3: Start the engine and determine which carbs have to be adjusted. If there is a master carb all the others will have to be adjusted to match it. If all the carbs are adjustable find one that is nearest to the middle reading and use it as the reference carb. Adjust the carbs until all the columns are within 2cmHg. The carbs are very sensitive to adjustment and even doing up the locknuts can affect the readings. There are special tools available from the importer to make this easier but you can do the same thing by using a small box spanner to hold the locknuts and with a long screwdriver down the centre to turn the adjustment screw. The individual adjustment screws can be found on the side of the carbs or on the operating linkages. On some carbs they are under the carb tops which have to be removed. Some models have spring loaded adjusters which are easier to adjust. Where each carb has an individual adjuster check to see that each carb has enough adjustment left. If one is almost out of adjuster threads then turn all of them back a couple of turns and set the cable adjuster and master idle screw to match. On older Suzuki models with CV carbs (except GSX400F) the two outside carbs are set 2.5 - 3.0cmHg higher than the inside pair. For specific model details consult your workshop manual or the Suzuki importer. (If the airbox has been removed set all the carbs the same). Adjust one carb and then check the reading. Give the gauge a few seconds to settle after each part adjustment. It is often necessary to gently blip the throttle to seat the carb that has just been adjusted. Step 4: When all the carbs are within 2cmHg tighten the locknuts, making sure you don't upset the readings. Switch off the engine, remove the gauge fittings and replace the blanking screws or caps on the bike. Replace the petrol tank and ride the bike for a few minutes to get it to its normal temperature, then set the idle speed with the master idle screw. Modern bikes hold their carb settings very well and you shouldn't have to adjust them more often than once every 5,000 miles. Older machines can be more difficult to balance to within 2cmHg and need more frequent adjustment. Bikes like BMW twins with separate cables for each carb also need more frequent adjustment. What do the readings mean? The actual readings aren't important as long as they are within the manufacturers specifications. It's the comparative reading that's important not the absolute values. If one carb has a significantly different reading to the others there can be several reasons for it. It may be at the end of it's adjustment so you'll have to back off all the adjusters and start again. It may be that a rubber tube has been wrongly routed so that you have been adjusting the wrong carb or that the rubber tube is kinked or flattened on its route to the carb or is loose. Possibly there is a leak in the carb to airbox or carb to head joints. It may be an engine fault and a compression test can help to pinpoint the problem. As long as the rest of the bike is in good tune and you have some patience you will find it fairly easy and very rewarding to balance the carbs. Information on the Gauge. Gauges do not need to be zeroed or calibrated. All parts have been matched at assembly. Damping of the gauges and friction of the rods may be slightly different in each column. This does not affect final readings, only the time it take to get there. If dirt or grease gets into the gauges and makes rod movement sticky then they can be cleaned. Lay gauge flat on its back and remove the two screws from the bottom cap. Slip off cap and front of case and the rods will be exposed. (Do not lose soft sponge pad in cap). Important- Each rod and spring must go back in its original position. Do not mix. Do not put loose springs together as they will tangle. For simplicity only remove one rod at a time for cleaning. Carefully remove spring from rod and polish rod and inside of rod guide with a cloth. Do not scratch. For severe staining use a brillo pad or the finest steel wool to polish rods. Wash or clean thoroughly with cloth afterwards. If clear tubes are stained remove all rods and springs and put some water and washing up liquid inside the clear tubes and gently shake. Let it soak a while then rinse out all trace of detergent. Blow dry with an airline, cool hairdryer or let it dry naturally and dry rod guides with the corner of a cloth. Only assemble when dry. Do not remove top cap. Do not remove clear tube assembly from casing as it may affect rod alignment. Do not remove clear tubes from the connector blocks as they may not reseal. But remember "if it ain't broke don't fix it." Spare parts are available from Morgan at the address overleaf. Ring or write for price details. The Carbtune II and previous Carbtunes have been tested and used on many different bike, car, marine, and aviation engines. Obviously we cannot test every bike, car, boat or plane so if you encounter any problems with the operation of the gauge or find the supplied range of fittings don't fit then please contact us with the details. Quite often problems can be quickly sorted out over the phone. GUARANTEE Carbtune is guaranteed against defects in materials and workmanship for a period of 12 months from the date of purchase. Should your Carbtune be damaged through such a defect, please contact the manufacturer, details overleaf. We will repair or replace the equipment (at our option) provided you have followed the usage instructions. This does not affect your statutory rights as a consumer.
