you cant remove limiter CDI is limit in eprom. if you can remove the 4 º degreus ****** in ignition them you will get with full exhaust 20cv. with 20cv you change the front sprocket from 14 to 15 and your bike topspedd is is 147 kmh. regards

I am not Fimiliar with this motorcycle but where the side stand attaches to the frame get down there a see if there is a side stand safety switch it may be stuck in the if you have that see if you can work it in and out.

Either your coolant has a low top temp range (+102C for example) or you're running on lean mixture. Also check if your thermostat works and opens as it should.

depends on a matter of causes, was the tank full or empty? or halfway? have the fuses been checked? from what you seem to be describing (although its a bit hard and im having to guess wildly) if the tanks low, its sucked some **** through the fuel system and blocked an injector.or it could be something totally out the ordinary and an oilway has been blocked and its in a failsafe to prevent further damage.give me some more details and i may be able to help a bit furthere.g. speed, fuel used, any other weird problems

its starving of fule running week, it revs standing still but under load it dieys,, clean out all fule lines and taps jets or what ever,,,,also check air fillter,, and spark plugs,,

I don't see why not. The manual rates a service as "beginner level" - BUT i would suggest that you gat a manual and then make sure you have everything you need before you start. ie: oil , filters, plug etc. In the event that this is your first attempt at servicing a motor, I would suggest that you take it to a bike shop and watch as they do it. Then you will know where everything is and what tools you need. It isn't a job for a first timer.

Hello and happy thanksgiving.As you must know the fuel injection on this is electronic, the fuel injector is turned on and off very quickly by the computer control module referred to as the "ECM" to supply a metered amount of fuel to the engine as needed based on the inputs from the various sensors such as the throttle position and other sensors, this is called injector "PULSE" to check and see if your injector is pulsing you will need to buy a little tool called a "NOID" injector tester, it plugs into the injector connector and when the engine turns over the Noid will flash very quickly. Also you have never mentioned whether you have had the ECM (computer control module) tested for fault codes, when it senses a problem or a sensor that is out of normal range it will record a code for this fault. You will need the factory tool (called a scanner) to do this test it is essential that this test be performed or more wasted money can be spent on replacing perfectly good parts. You can buy a Noid tester from any auto parts store like NAPA, just make sure your bike has the standard BOSCH fuel injector connector, it the connector is a different design then you will need the factory tool.

Hi,If there is fuel coming from the injector and you're sure about it.Better get a CDi from a friend and test it, looks like a CDi problem.Tell me more after you replace the CDi.............

when it is available in chennai ? ? ? ? ? ? ? ? ? ? / ?

Ohm out with a meter the "bad" injector and compare it to the other cylinders. This may tell you if you have a bad injector.

you put the oil in through the dip stick, and the oil i use in 4stroke bikes is silkolene 4t 10W-40

Check your ignition components for condensation. If you wash the bike using water especially around the motor, you should promptly dry it thoroughly before starting it to avoid the possibility of condensation caused shorts in the ignition system. I personally use a leaf blower to dry mine and let it sit in the sun for a while to make sure it's dry. I think you will find condensation is your problem. Good luck and safe riding.

is the bleed nippel on top of brake or bottom.

is it getting power?? is the efm working the way it should

Removing the muffler will not hurt the exhaust system, however it changes the air flow through the engine and will cause it to be lean and stumble on acceleration. As far as who can remove it, you can if you are mechanically inclined and have a good set of hand tools.

Hi Davidroyal, because you do not specify what type of Yamaha is I'm just sending you this electrical diagram of the XJ'S that I have for a while and may be can be usefull for you.
Good luck mate.

Can you be more specific? Do you mean how to replace or just what is the question.
