cc is the size of the engine, in cubic centimeters - literally the volume of the cylinders. A larger cylinder can ingest more air (and more fuel), thus converting more energy per cycle than a smaller one, so making more power - assuming all other factors are the same, and there are many factors that affect power output. You can measure it by a simple volume ...

The reason is that motorcycles traditionally have the fuel tank higher than the carburetor, and the fuel feeds with gravity alone. What risks does this introduce that necessitates a manual shutoff? Without the shutoff, if the carburetor float failed to close the valve tightly enough to stop the fuel flow, then gas would continue to trickle into the carb, ...

Two of the useful features of this setup (I have no evidence to prove they were the design reasons) are: when braking in a hurry stamping down until you reach the bottom will leave you in first, NOT neutral. This is much safer in many respects than being left with no power in an emergency situation. when starting from neutral, there is no risk of ending up ...

My knowledge of motorcycles is limited so I could be wrong, but it sounds like the clutch is slipping.

Chain maintenance is critically important for motorcycle safety. If this old chain has not been properly maintained throughout its life, you may be at higher risk of seized links or chain breakage. Best case scenario with a broken chain is that it comes off the bike cleanly and you coast safely to a stop, avoiding any encounters with surrounding traffic. ...

RainX makes an anti fog product specifically for use on windshields, but I don't see why you couldn't use it on a helmet visor too. To be honest, in my experience using it on windshields it doesn't work all that well, but it's better than nothing. Alternatively there is a wide variety of anti-fog solutions made for sucba diving masks that I have had a lot ...

nope, not at all. I have a z06 vette and the engine has so much torque that I can easily go from 1st to 5th. Under normal driving I skip gears all the time. Generally transmissions don't really care about which gear you want to use next.

Your questions don't appear to match the headline, but to try and help: Why are gears used when there is automatic gear technology? Because automatic gears have more losses- so you don't get as much efficiency from your drive train. Because automatic gears can't read your mind and may not choose the best gear for what you want to do. Because the ...

On most bikes the carb has an overflow port that drains through a tube to the ground. This is important if the float sticks. Usually you can tap the float bowl with a screwdriver and unstick it, but if it happens again, overhaul the carbs. Also, don't smoke around a bike that's dripping gas.

Very untrue. Both car and motorcycle engines are designed for gasoline, and just like cars, using higher-than-specified octane gasoline provides no advantages (unless you're advancing the timing or other modifications, in which case you'll tune for a certain minimum octane). High compression or forced induction designs (turbos and superchargers) in both ...

If the chain is not lubricated it will wear prematurely.The chain does not stretch but grows in length as the pins and barrels wear.This has the effect of changing the distance between the rollers.As the chain grows it will no longer match the pitch of the drive sprockets, the sprockets will wear out prematurely.If you then change the chain it will be worn ...

Lack of lubrication does lead to premature chain and sprocket wear, and loss of drivetrain efficiency. However, more important consideration in this case is safety. Safety It is absolutely essential to keep the chain cleaned and lubricated to prevent catastrophic failure that at best would result in snapped chain, and at worst can lead to binding and ...

You'll find the following will all affect your speed and acceleration: wind speed - a head wind will slow you down more than you would think your clothing - this directly impacts drag bike configuration - you'll go slower with panniers on than with them off weight - a full tank will mean you accelerate more slowly temperature - cooler air can give you a ...

It's my understanding with the current manufacturing technology it's not necessary anymore, on new cars, now there may be differences in motorcycle engines as I am not as familiar with those. With that being said we ask the customer to come back in 500 - 1000 miles for a free oil change on the engines we build and install. We do this for a couple of reasons, ...

If it was me - I would get the tyre replaced. In a car I would think about plugging it, but there I have 4 wheels and a nice strong rollcage and airbags. And even on a car tyre, plugging isn't that simple - there are things that can go wrong if you haven't done it before. On a bike, my safety is worth considerably more than the cost of a replacement tyre. ...

Converting existing vehicle to a hybrid is a difficult proposition, and even more so with motorcycle due to limited space allowance. Motor and Drive-train In a small motorcycle like that one would have to go with the wheel hub motor like that: Those could be fairly expensive, plus there is an additional cost of re-spoking the rim with this hub, and ...

According to the Ducati Monster 400 owner's manual there are several major things that should be replaced every 20000 kms meaning the bike your looking at should have had these things replaced twice already. Chances are that if they are selling it they didn't bother with the latest expensive maintenance items. You'll have to inquire about those things or ...

I would say yes to both of your questions. If you have some ATF (Dexron or whatever) sitting around, squirt a "bit" into each cylinder through the spark plug hole before you do this. You don't want to drop a whole bunch in there, but enough to wet the rings (a couple of squirts from an oil can or the like should be sufficient). This will create a small ...

It might be worth checking to see if the wear pattern looks odd at all. I've heard that if you're wheel is out of alignment or unbalanced it can cause excessive and distinctive tyre wear. See this page for a fairly comprehensive treatment of tyre wear: http://www.rattlebars.com/tirewear/index.html Having your suspension set up very hard can make you go ...

Since its paper based, your ability to clean it is somewhat limited. Mechanically agitating it (i.e. with a brush) is iffy since you run the risk of damaging the filter element. You can try shooting compressed air from the opposite direction of the filter but that really only removes the larger chunks of dirt, and if you're not careful, can also damage the ...

A good place to start looking is the fuel filter, particularly if you didn't put fuel stabilizer in the tank before putting the bike in storage. You can test to see if it's clogged by blowing on the line-in, but if you don't like gas on your lips fuel filters are cheap, and replacing them regularly is a good idea anyway.

In India, if you're bike has an exposed chain, it will collect grime. Lube your chain at regular intervals to keep it in top health. Also, I think the 180cc Avenger is still carburetor based, and the carb needs to be cleaned at regular intervals along with the filter element in the air filter box. Your owners manual will show the location of the oil sump, ...

To some extent, the answers will be dependent on model you are looking at, the amount and types of customization that have gone into the bike, and the amount and type of actual use it's experienced. If it's been to the track (probably not an issue with touring bikes or cruisers, but certainly possible with sportbikes), wear and tear on the drive train will ...

You can install an external tachometer that reads your wheel speed. There's one on Amazon for Kawasaki for $19USD. Some clamp onto a spark plug wire, others are 2 piece, where one small piece clamps onto your wheel, and the other clamps onto a fork and measures the wheel RPM - but those are more for bicycles, not motorcycles (where you'd like engine RPM - ...

These ways to repair tires can work - the air pressure inside the tire does hold the patch to the body of the tire - but the question you want to ask yourself is: Are you willing to trust your life to a weaker tire when a small amount of money will get you a brand new tire? I would always go with the new tire if I have had a puncture on my motorbike - the ...

I'm not sure how long any sort of grease would last before it worked its way out? I'd be tempted to go for a more mechanical solution (if you have access to appropriate tools, or a frielndly machine shop) - drill a small hole in the socket and tap it to a suitable thread, then insert a grub screw to bear onto the side of the ball and stop it moving. That ...

Your question raises more issues than you probably thought. With respect to the issue of a relay, then assuming your bike has a 12 volt, negative ground, electrical system, all you need is a generic automotive relay, which looks like this (sometimes called a Bosch relay, regardless of whether it is actually a Bosch unit). Here is an article, which looks ...

The right side looks like it has a small crease. You may be able to get it to look better but I don't think it will be perfect without some filling and painting. You can try covering the filler opening with some heavyduty plastic and installing the gascap. Hook the fuel outlet up to an air compressor. Gradually increase the pressure to see if the dent will ...

Where possible, have as few electrical items switched on as possible when you start a car or bike. You want to do this any way, as if the battery is a bit low, the load can drain it rapidly and you may not start the engine, but in any case you will require more recharge cycles, which will reduce its life. Additionally, if the current drawn is too high you ...

I'm assuming that the bike shifted better at a standstill before the rebuild, otherwise you wouldn't be asking...but nonetheless, many motorcycles are difficult to shift at a standstill, it has to do with the engagement of the "dogs" on the gears. When the bike is at a standstill, the output side of the transmission is also at a standstill, so the dogs ...
