motorized bicycle that run off the engine.need to know voltage’s,bulb sizes,etc. I want head light,brake and tail light, switches. I have a rupp mini bike diagram that shows no bulb sizes,voltage,watts and no battery but I can use one if I need one. are there options? what are they? I’d like nice bright lights but I don’t know electrics at all. I need idiot proof instructions. Please Help! thank you

How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
By swapping out your rear sprocket for one with a different number of teeth than your stock one, you change the gear ratio your motorized bike runs at. This will change the drive train of your engine for a faster or more torque-y ride depending on the sprocket you go with.
The maximum speed of 80cc mini bike is 23 mph.
The top speed of 100cc bikes ranges from 50 to 70 mph (80 to 112 km/h) on average, but most production models are capable of 50 to 60 mph. In contrast, the world record speed of this engine type exceeds 116 mph (around 186 km/h).
Intervals in a higher gear: Cycling in a bigger gear increases strength and power. Warm up on a low gear and then increase it and pedal hard for 2–3 minutes, and then shift into a lower gear for a 3-minute recovery. Repeat this exercise 10 times.
With a 1000cc engine producing upwards of 170 hp, this bike can reach a top speed of 185 mph and complete its 0-60 mph in just under three seconds.
80cc Engine – 5.0HP.
80CC Engine Carburetor Size: 4.25″x2.
In carburetors that employ a power valve there is still a metering jet that controls the majority of the fuel control, however there is also a small valve that opens under wide open throttle conditions to deliver extra fuel for maximum power.
Find the adjustment screws on the front of the carburetor.
There should be two screws on the front of the carburetor, which are used to adjust the air and fuel mixture. These often look like flat-head screws, and you can use a screwdriver to turn them, adjusting the amount of fuel and air mixing in the carb.
The 25cc hub engine in the Wheel delivers 1hp (0.8 kW) peak power at 7,500 rpm and supports a top speed of 20 mph.
For example, a 150cc scooter has a top speed of 60 mph and may get up to 70 mpg, while a 250cc scooter can reach 75 mph but might get fewer than 60 mpg.
3: What Causes an Engine to Lose Power
Anything that impacts the air, fuel, compression or spark within the engine can cause it to lose power. Some issues may be as simple as a dirty air filter, while others may be more complex issues that affect the fuel injectors or spark plugs.
Because combustion takes place with each revolution of the crankshaft with a 2-stroke, this format puts out more power than a 4-stroke engine and the power has more instantaneous delivery. This are some reasons why 2-stroke engines have a long history of use on many different types of motorcycles.
Try hill repeats and riding intervals once a week to train your aerobic system and leg strength. This will certainly improve your overall cycling power. Riding further and joining faster cyclists on their rides will also help to improve your fitness and cycling wattage.
In the end, the fastest bikes use the elements of racing bikes – supple tires, aero riding position, a frame with flex in the right places – but their tires don`t need to be narrow.

A 1000CC engine would produce anywhere between 80+ BHP.
Industrial engines typically produce about 3 HP for every 100cc of displacement. High performance automotive engines can produce 7 HP for every 100cc, as do many two-stroke engines.
450cc dirt bikes are great for recreational and enduro riding and can reach speeds of 80-120mph.
650–850cc—
75 MPH With a max speed this high, you`ll be hitting speeds of 40–50 MPH regularly on trails. With 700cc of displacement, this ATV can put out a lot of power. If speed is what you`re after, this quad will give it to you… at least until you hit the built-in rev limiter at around 75 MPH.
How fast is 125cc? Most production 125cc motorcycles have top speeds of 90-115 kmph (about 60-70 mph).
The ideal chemical air-fuel ratio, in which all the fuel is oxidized, is 14.7:1, that is, 14.7 parts air to 1 part fuel.
For peak power, most engines like an air/fuel ratio of 12.8 to 13.2. If you can tune a carb to deliver a consistent A/F within this range, the engine will usually run at its full potential from off-idle to wide open throttle. The air/fuel ratio will change with ambient temperature, barometric pressure and humidity.
Black Exhaust Smoke Black smoke, whether steady or just when you accelerate indicates a rich fuel mixture. This means the carburetor is using too much fuel in the fuel/air mixture. As you can imagine, this rich mixture burns excess fuel which is why you get fewer miles to the gallon. It also emits excessive emissions.
Spark plug wire boot grounding out on coil, 96 outback 2.5 automatic, just put new spark plug wires, new spark plugs, and new coil on. ran great for two weeks, now spark is jumping out of boot at coil on one wire, put old coil back on and still does it in the same spot. replaced wires again, and still does it in the same spot. seems to do it only under a load. Is my new spark plug on that cylinder bad? Does the coil need some insulation under it? It is the coil that sits right on top of the motor. Any ideas? thanks.
ANSWER : Sparks are high voltage, and will always follow the path of least resistance. If you can visibly see a spark (whether in a lighted area, or in the dark), that means either that a plug wire (or coil wire) is open (non conductive), or your have a carbon track on the surface where the spark can be seen, but most likely you have BOTH problems!
If you have an ohmmeter, check the resistance of each wire involved, particularly spark plug wires … which means you must be able to connect to both ends of each wire at the same, and hopefully, FLEX those wires, to be sure they don’t have a break inside that is intermittent (comes and goes)!
