It laid down the concept that is still in use today: a two-cylinder boxer engine with a longitudinal arrangement and a cardan transmission were considered quite progressive solutions at that time. In , it was the BMW motorcycle that set the absolute world speed record, accelerating to kilometers per hour. Until the eighties, the motorcycle division of the company was actively developing, and produced various versions of its boxer cars, the most striking of which was the GS family.
Today, BMW is one of the largest and most important motorcycle manufacturers, distinguished primarily by advanced technologies, innovations, and a high attention to comfort and safety.

Plans for an old "Pre-Shreckling" prototype Jet Turbine Engine - plans are incomplete and not detailed. The design probably would not produce enough thrust to be anything more than a static display model if it could reach self sustain speed.
Obsolete Design and very heavy build. Often sold as Home built Jet Engine Plans. It is rumored that these Turbo Jet plans if they can be called that are still for sale today on the web - beware of any daemon you may come across while searching for a Jet Engine Plan - you may be a victim of one of the longest running Jet Plan scams of all time.
The new online seller of this attempt at a miniature Jet Turbine Plan Set now includes a claim that their plans have been "expanded to include all necessary details".
This proves that the plan set in it's previous format was incomplete - and is still based on the obsolete and non practical Savoy Daemon Gas Turbine prototype. Remove the radiator cap and connect the radiator tester to the filler. Pressurize the cooling system with kPa 1. The engine must be cool before servicing the cool- ing system.

Disconnect the air cleaner breather hose and loosen the car- buretor clamp. If any damages are found, replace the spring or rear shock ab- sorber with a new one.
Low gas pres- sure can result in oil leakage. Abnormal gas pressure cannot provide normal performance of the rear shock absorber.
Be sure to fill the rear shock absorber unit to the speci- fied pressure. Disconnect the brake hose from the brake hose guide. Remove the cushion lever mounting bolt and nut. Inspect the spacers for any flaws or other damage.
If any dam- ages are found, replace the spacers with new ones. If any damages are found, replace the swingarm with a new one. If there is excessive play, re- place the bearings with new ones. Page Reassembly And Remounting Reassemble and remount the rear suspension in the reverse order of removal and disassembly.
Remove the brake pads. Do not operate the brake lever during or after brake pad removal. Replace the brake pads as a set, otherwise braking performance will be adversely affected. Install the new brake pads. Remove the master cylinder reservoir cap and diaphragm.
Remove as much old brake fluid as possible. Fill the reservoir with new brake fluid. Specification and classification: DOT 4 Connect a clear hose to the air bleeder valve and insert the other end of the hose into a receptacle.
Remove the spring. Place a rag over the brake caliper pistons to prevent them from popping out, and then force out the pistons using com- pressed air. Do not use extremely high pressure air to remove the brake caliper pistons, otherwise damage to the pistons will result.

When connecting a connector, push it in so it is firmly attached. Inspect the connector for corrosion, contamination and any breakage in the cover.
The MF battery used in this motorcycle does not require main- tenance e. Improper use can cause damage to the motorcycle and tester. If the voltage and current values are not known, begin mea- suring in the highest range.
When measuring the resistance, make sure that no voltage is applied. The regulator prevents overcharging of the battery by grounding the excessive AC current. Remove the battery cover. Measure the current between the - battery terminal and the - battery lead wire using the multi circuit tester.
If the reading ex- ceeds the specified value, leakage is evident. Measure the AC voltage between the lead wires of the genera- tor using the multi circuit tester. Pressing the starter button energizes the starter relay, causing the contact points to close, thus, completing the circuit from the starter motor to the battery. The starter motor draws about 80 amperes to start the engine. If any damages are found, replace the brush assembly with a new one.
Page Starter Motor Reassembly And Remounting Pay special attention to the follow- ing points: Replace the removed O-rings with new ones to pre- vent oil leakage and moisture. Remove the starter relay. Apply 12 V to the terminals and check for continuity between the positive and negative terminals using the multi circuit tester.
This energy is released in a single surge at the specified ignition timing point and the current flows through the primary side of the ignition coil. NOTE: The ignition coil peak voltage Correct inspection method is applicable only with the multi circuit tester and the peak volt adaptor.
Connect a new spark plug to spark plug cap and ground it to the cylinder head. NOTE: Make sure that the spark plug cap and spark plug are connected properly. Measure the ignition coil resistance in both the primary and sec- ondary windings using the multi circuit tester. If the resistance in both the primary and secondary windings is close to the speci- fied values, the windings are in sound condition.
Measure the resistance between the lead wires using the multi circuit tester. If the resistance is not within the specified value, the pickup coil and signal coil must be replaced. This en- ergy is released in a single surge at the specified ignition timing point and the current flows through the primary side of the ignition coil.
Correct Incorrect Correct Incorrect Incorrect Connect a new spark plug to the spark plug cap and ground it to the cylinder head.
