Same way on all k75 k100 motorcycles. With the engine off twist the throttle and look at the the part that moves on the throttle bodies about 1 foot below the gas tank near your left knee as you are sitting on the motorcycle. Make sure the bike is fully warmed up - take it for a 10 minute ride. Aim for about 1000 rpms at idle. Loosen the lock nut and turn the screw clockwise to increase the idle and counter clockwise to lower it. Mrbios '92 k75s w/ 63K miles San Diego, ca To balance the 4 (or 3) cylinders, you will need a carb stix or similar device, to measure (and balance) them as you adjust the idle screws.

1987 bmw motorcycle k75 oil?
BMW recommends ONLY using BMW oil that can be purchased at their dealerships for their motorcycles, including the 1987 K75. For the transmission, you can use 1 Quart Mobil-1 GL5-75/90 or Castrol SAF-XO GL5-75/90 Synthetic Gear Oil.
What causes premature ring and bore wear in BMW K75?
Using the wrong (detergent) oil is one possible cause.
How do you change a battery on a k75 motorbike?
1. unlock seat with ignition key.2. push the lock in to un-latch the seat and lift it up.3. open the lid on the box under the seat.4. insert a screw driver in a hole there and push tab out of way while pulling on the computer / fuel control module cable.5. remove that box / computer / tray.6 undo and remove battery hold down.7. disconnect battery cables.8. loosen plastic fender at base near battery.9. rotate battery 90 degrees.10 lift it up and tilt back and pull it out. You must buy a manual for the BMW k75 - you will never figure it out even if you have work on other motorcycles. The BMW (expecially k75 / k100) is designed really weird like no other motorcycle. You need the manual and the internet and there is only ONE way to do things any other way will cause problems. I know I have owned a '92 k75s for 6 years and done many repairs. Mrbios
Describe the instrument cluster on a K75?
Go here: http://www.ibmwr.org/ktech.shtml http://www.ibmwr.org/ktech/trip-odometer.shtml http://www.ibmwr.org/ktech/speedo-moisture.shtml http://www.ibmwr.org/ktech/tach-fix.shtml They were made by motometer and are prone to many different problems from fogging, trip meter breaks, backing warps in direct sun light (south western United states), connectors corrode, etc. The plastic backing can be replaced with tin to prevent warping. The bike will run correctly with out it being hooked up. -Mrbios '92 k75s
What are the different motorcycle engine configurations?
Here are the most common engine configurations as summarized in Timberwoof's Motorcycle FAQ.Single: Called a �thumper.� Most dirt bikes, many small motorcycles, and the following BMW models: F650, R20, R23, R24, R25, R25/2, R25/3, R26, R27, R35.Inline Twin: two pistons side by side.V-twin: Harley Davidsons, Ducatis, Honda Hawk and Superhawk, Moto Guzzi, and a couple of Suzukis including the wonderful SV650. The 90-degree twin is very well balanced; other angles may or may not be, depending on whether the crankshaft has one pin or two.Flat-twin: classic BMW design offers good balance and natural air-cooling. Also called a "Boxer" or opposed-twin engine, the firing of one cylinder helps cancel vibrations from the firing of the other cylinder. Also used by Harley-Davidson in the XA motorcycle copied from BMW during World War 2. See also the Ural - a Russian motorcycle reverse engineered from wartime BMWs. See also the Japanese Marusho motorcycle, yet another BMW copy.Inline-three: Three pistons in a line. Typical examples are Triumph and BMW K75. Historically seen in Kawasaki 2-stroke form in the 1970sInline-four: Staple of the UJM or "Universal Japanese Motorcycle," found in everything from the 400cc Honda CB-1 to the 1200CC BMW K1200. In the UJM it's mounted with the crankshaft sideways; in the BMW K it's mounted with the crankshaft aimed north-south and the pistons off to the left. Imperfectly balanced, with the potential to be objectionably "buzzy" in the absence of balance shafts or vibe-damping motor mounts.V-four: Honda VFR 800 (sideways) and ST1300 (longitudinal): smooth like a four and balanced like a twin.Flat-six: Honda Gold Wing and Valkyrie: smooth torque monster with low center of gravity. Possesses perfect natural balance without the use of balance shafts or vibration damping engine mounts.Inline-six: An awkward engine to package efficiently, but with the same perfect balance inherent to a flat 6. See the Honda CBX1000, Kawasaki KZ1300, and Benelli 750 and 900 Sei.Square four: As in the Arial Square four. Four vertical cylinders arranged with the center axis of each cylinder at each point of an imaginary square as viewed from above, looking straight down. A mechanically complex arrangement that is difficult to cool with ram air.V-eight: Rare. Currently only used in Boss Hoss motorcycles - usually a General Motors engine. Used in a record-setting Moto Guzzi in the mid 1950s, also occasionally seen in a custom bike, by mating two inline-4s.In addition to the comprehensive answer above, additional flat twins (boxers) were made by the Chinese, the Russians ( BMW copies) as well as Zundapp, and one by the Japanese. Thumpers come in varying configurations- depending on the angle of the cylinder which can be nearly flat as with Aermacchi 350 and Moto Guzzi Falcone, and at an angle of around 45 degrees in Panther and BSA Sloper. Of course most other single cylinder 4-strokes vary from upright to a few degrees off vertical, such as the approx. 24 degrees of the Vincent Comet. Two-strokes have come in some weird configurations, Honda made a V3 for a few years (two cylinders nearly flat in front, one nearly vertical, like a Ducati, with three carburettors in the "V"). Also, some "inline twins" (more commonly known as parallel twins) have the cylinders "fore and aft" i.e. longitudinal, like the Sunbeam.
What is 75 degrees Fahrenheit?
Start by taking the number in Fahrenheit and subtracting 32. Then divide the number by 9, and then multiply it by 5. This is how you convert Fahrenheit to Celsius or use the equation C = (F - 32) × 5/9In this case, the answer is about 23.89 degrees Celsius.
