You can learn about motorcycle engine repair at ITT Technical Institute. They have a numerous amount of programs and that is one of them if you want to work on motorcycles.
It would largely depend on why #6 has no compression. It could be a minor repair or it could be a major repair. If it is a major repair and the engine has high mileage it would be wise to replace the engine only if the vehicle is worth saving.
Not worth repairing the engine... look for a low milage engine at a wreckers and have a knowledgable person do the engine swap... I imagine you could likely get the engine and install for ~$1200-1500 if a 'jober' does the install
American, Sylvester Howard Roper (1823-1896) invented a two-cylinder, steam-engine motorcycle (powered by coal) in 1867. If you allow your description of a motorcycle to include a steam engine, then Howard Roper could be considered the inventor of the motorcycle. Howard Roper also invented a steam engine car.
There is no one motorcycle, and no one answer. It could be 5 hp or 100 hp. The 2018 Harley Road Glide has 77.34 hp
The Honda CB125 was a motorcycle made by Honda. The motorcycle was manufactured from 1971 to 1975. It had an overhead camshaft engine, and could maintain speeds of 89km/h.
Depends on type and condition. It could be worth 15 grand or more and it could be worth scrap value.
Theoretically the rotary engine could last up to 200k miles but it depends on how hard you drive the engine
The weight of a motorcycle engine depends on the size of the engine. It could weigh as little as 35 pounds up to 95 pounds for a large engine.
Several things could be causing that, but a typical "engine knock" usually signifies the need for a replacement engine, or a complete overhaul of the engine. I would recommend a replacement, and I would go with a Jasper product if you can. I work for an automotive repair shop, and we install dozens of them every year, and we have never had a single problem with them. They are definitely worth the money.
Not really, the engine has little mass and will just stop. Stalling will stretch primary and drive chains perhaps and could put excessive strain on the transmission.
A good torque wrench is an essential tool for even the most basic motorcycle maintenance and repair. It's important to ensure that all of the fasteners on a motorcycle are tightened to specifications for reasons of safety and to maintain its original design integrity. The torque wrench is used for tightening and loosing bolts on the motorcycle so you could improve the torque of the motorcycle therefore increasing its overall throttle. It could be used on the Yamaha Z5000 to either loosen or fasten bolts based on weather conditions.
I see a motorcycle that has a 420 bhp engine built into it for some reason and another reference to a 2200 bhp jet engine and another for a 9000 bhp engine, so it could vary quite widely depending on the size of the engine.
