You are describing a lean condition The more you open your throttle the more vacuum you are creating in your carburetor venturi and your intake manifold. When you are operating at higher RPM any unmetered air leaks into your system can become more obvious. Unmetered air is air that is getting into your system after the fuel has been delivered. If you ...

It sounds a lot like a fuelling issue to me, I'd suggest a systematic approach to the carbs. Get the workshop manual for the bike and try the following: Check fuel supply Check float level Check idle mixture Check that jets are clear Check that all vacuum hoses are routed and connected correctly Check that carb diaphragms are intact and needles slide ...

The thirty amp fuse is your main fuse To ensure we are speaking using the same nomenclature, K1 is referring to model year 2001 in my verbiage. This 30 amp fuse supplies all the power to your fuse block with various 5, 10 and 20 amp fuses populated. I have quite a few hours on this bike and have seen a scenario that you are describing. Here are some ...

If you're only considering top speed and not acceleration then the number of gears don't matter. The only thing that matters for top speed is aerodynamics and the power to overcome wind resistance.

The question as asked has no real answer, so let me explain a few topics that will point you in the right direction. The number of gears has no effect on top speed. The ratio of each gear is the important part. You could conceivably have a 3-speed transmission with a higher top speed (for a given RPM) than a 7-speed transmission. Having more gears can ...

I use a brass brush and kerosene on my chains (both bicycle and motorcycle). it works great and i have never had a problem. i have read that WD40 is inadvisable on o-ring chains, as it can displace the lubrication behind the o-rings. not sure how accurate that is. My neighbor cleans his chain with WD40, and it hasn't flown off the bike while running yet...

It depends There are too many other variables such as: Wind resistance at top speed of the vehicles Loss of power through the various components from the engine to the rear wheel Gear ratios We can get some of this information, such as gear ratios, but the other components necessary are beyond our reach. I don't believe your question can truly be ...

You can buy a special tool to clean the chain, it is normally circular/spiral shaped and you twist the brush as it runs along the length of the chain. http://www.jpcycles.com/product/ZZ36383 Also, you can purchase a special chain lube tool, that basically hugs the chain and has a hole to insert a straw.

I would use something like WD40, and a soft cloth to rub the rust away. Then apply the right amount of chain lubricant and you will be good to go. You can use a brass bristle brush, provided you do it gently like this guy in the video. A toothbrush will also work. This is light surface rust and IMHO nothing to worry about too much.

In any motorcyle you CAN shift into gear without using the clutch, you have to match the engine speed with the output speed, many people use it for racing, and if done correctly does not cause excesive wear, but for normal use, it is not recommended. now when you say it wont shift into gear, do you mean the shifter just come to a halt before the shift ...

If I then pull the clutch and completely stay of the gas, the rpm stays at 6000 and doesn't drop Sounds like you did something wrong during the rebuild, all you can do is pull the carbs and check your work, also check throttle cables for proper routing and adjustment. Did you clean the fuel tank valve and screen?

15w50 you can use for Apache rtr 160. It's recommended and bike is very smooth with it.

It takes three things to make an engine go. Spark, fuel and air. So perhaps something controlling each of those three things isn't working well. No way to guess here. Just start checking each of those. If you are mechanically inclined, I'd start the search by troubleshooting with the service manual. Page 13 of that manual is a very detail troubleshooting ...

A battery can run lights but not have enough energy to run a starter, Check the battery connections, be sure they are clean and tight. Check water levels in the battery, fill if needed, then put a 1amp charger on it for a few hours. If you get it running again check the voltage at the battery while running with a DC voltmeter, it should be 13.5 volts or ...

This sounds like the kickstand safety switch has gone astray. Almost like the switch gets stuck and the bike thinks the kickstand is still down when its not. After 'wobbling' the bike, the switch gets unstuck?

If anything, your bike should be running lean Thoughts You put an aftermarket non-restrictive exhaust on your MV, that increases the flow of gasses which requires more fuel to compensate for the additional flow. So, the idea that your bike is running rich doesn't really resonate. It certainly can be and if it is it could be indicative of another issue ...

Generally manufacturers aren't going to waste money on unnecessary components. You've got electrical components to: provide spark to the engine. an on/ off / kill switch to control engine on or off. power the fuel pump (on a modern fuel injected bike). power to the engine control computer, and its sensors and subsequently the fuel injectors (on a modern ...

It seems as though the plunger in the master cylinder isn't retracting after use Occasionally when motorcycles are stored you can run into this problem. Older brake fluid along with a bit of moisture and oxygen can contribute to a buildup of material inside the master cylinder bore where the plunger goes. After pulling the brake once the plunger sticks ...

I left it for another couple of months in a well ventilated area without riding, and lo and behold, it stopped leaking. Turned out that it may have been high fume/pressure in the fuel tank. Thanks for the answers!

After a lot of searching - I've found that nowhere in the manuals of warranty the engine oil grade is mentioned, i've also looked thru several forums where 10w40 to 20w40 grade of oil is recommended for TVS APACHE RTR 160 bikes by expert bikers and mechanics alike. Having used a TVS APACHE RTR 150 older model of a friend, he also used 10w40 for his, so i ...

There is a hose that connects your air box to this As stated in comments, this is connection point for a PCV hose. The hose connects to the bottom of your air box that attaches to your carburetors. This hole allows for crankcase ventilation. Any gasses that should not be released into the atmosphere can be vented here. It should get pulled back into ...

The Breather fitting is missing according to the diagram, you can buy one on Bike bandit. Original OEM Part number was 92005-1129 Also it looks like 92005-1017 may be a tube that attaches to it, but not sure, schematics are not that good. You could call BikeBandit on the phone to figure out what is missing.

The Royal Enfeild is a very old design. The motorcycle is based upon an old British design from World War II and has changed very little over the years. I do not know what type of quality control process the Indian manufacturing of the vehicle has implemented so that is very difficult to asses. It sounds like your gas cap vent or your fuel tank vent is ...

You can spend time identifying which cylinder is bad but in the end you need to replace both head gaskets If both head gaskets aren't failing the other one will fail soon. You may not know it yet but you don't want to replace just the single head gasket. You want to do both. If I were in your position I'd just order two new head gaskets and get on with it ...

You might have a tear in your CV carburetor diaphragm At the tops of your carburetors there is a cover with 4 screws that gives access to your CV diaphragm and slide. The CV (constant velocity) carbs adjust for barometric pressure automatically. The difference in pressure from your intake tract and the atmosphere raises and lowers you slide that has the ...

Your carbs are clogged with varnish and bad gas The remnants of gas that has evaporated are a gummy hard varnish inside of your carburetors. You have a bit of work to do. You need to completely disassemble the carburetors and thoroughly clean all of the nooks, crannies, jets, fuel galley's and air galley's in order to get your bike back in working order. ...

It sounds like your carb(s) are plugged and need cleaned. If the fuel in the carbs has ethanol in it, the carbs are going to be caked with crap. The floats could be ruined. There are a lot of things going on. Getting the carbs rebuilt or at the very least cleaned up, is going to be a must. All of the symptoms you saying are pointing to carb issues.

It won't damage your transmission unless it damages your transmission You have a shift drum. It has grooves in it around the outside diameter that the shift forks follow to slide gears into gear as the drum turns. This is the basis for a constant mesh transmission. It's the reason (other than regulatory) that motorcycles gears are shifted in numerical ...

I don't have experience on as many different bikes as some people, but here's what I have found. But "preloading" the shifter, were talking about pressing on it just a little before you are ready to shift. The force needed from bike to bike will vary, so it's something you will just have to try and figure out. A motorcycle transmission is not like a ...

You can adjust your valve lash You have nothing to worry about. Adjusting valve lash is a standard maintenance item and should be done upon any maintenance or tune up's of your vehicle. As you can see in the image, getting to the adjustment is quite simple. From there, follow your factory manual regarding reducing the amount of valve lash clearance. ...

You can ride it up but not hard at all That spider spring works in conjunction with the ramps in the rear to all the clutch to slip under engine breaking that exceeds the redline of the bike. So you won't want to be downshifting from 5th redline to 2nd gear until you get this fixed. You are very lucky the spring losing it's two arms didn't do more damage. ...

It's completely normal, nothing to worry about It's simply the gap between the sleeves. If you look from above, straight down, you will see a straight edge cut into the outside diameter of the metal sleeves that are pressed into the aluminum cylinder block. The straight edge is there so the sleeves can co-exist in close proximity without encroaching into ...

50 to 100ml should be OK That small of an amount won't hurt anything in overall scheme of things. Be careful not to put too much in though because you can do engine damage if you put in a large extra quantity. You will want to ensure you do not overfill your bike beyond the high oil mark in your oil window on the side of your clutch cover. This article ...
