Top 20 2004 Yamaha YZF-R1 Questions & Answers

There is a plug that goes into the instrument panel, check the connection there as the bike will not run if the ECM can't talk to the instruments.

first simple test is to see if the panic stop( engine kill switch) has been moved to off position. next is to see if there is spark--immobiliser or electronic fault.

Tilt sensors are usually a mercury liquid, or a ball and cage , and not really be reset, they can be adjusted by rotation or physically moving the unit itself.

Most tilt sensors reset when the bike come back upright or when the ignition is powered on and off.

You'll need to charge the battery for several hours then take it to O'reilley auto or autozone. they'll test it to tell you if its good. A volt meter is not always a reliable test. Second test (or first if you'd like) take off the ignition cover and put a wrench on the crank bolt to see if the engine spins. If these both test good, then you move to the fuse box

If it won't hold a charge, then the battery is no good.

Did you find an answer?

Turn clockwise the tensioner on your left lever all the way in.Loosen up the 2 nuts on the clutch cable's bottom end.Pull the **** (not especially hard though) and tight the nuts back.Then go to your lever's tensioner bolt and adjust the cable so that the lever's end (ball) should move 2-3cm before the cable stretches (freeplay 20-30mm)

You will need to remove the riders seat to complete this task, the seat is secured by 2 x 5mm alun key bolts, one in each corner of the seat, gently lift up corners and undo the seat, once removed the footrest brackets can be replaced

Check you charging system, with a volt meter is should show between 13.5-14-5vdc at the battery with the engine at 2000 RPM. Test your battery for load capacity and dead or weak cells...1 dead cell will drain the others. Hope this helps.

sound like a stuck injector, can you swap the injector into another cylnder

also check the valve clearances, perhaps a valve is stuck open

hi although it is a bit tight for space the least parts removed the better, with the middle fiarings removed you should see the top of the cylinder heads, remove each cap 1 at a time and replace the plugs using the spannner in the bikes tool kit, if this way proves to difficult you will have to prop up the fuel tank, remove airbox and get at the plugs this way,paul

error 46 is charging system not working normal, google error code 46 seems to be common on this bike

Ihad same problem it was a short in the big harness near radiatior.I jiggled it and moved it onto other side of radiator capand it solved my problem.

YES YOU CAN SEPERATE THE FAIRING BRACKET FROM THE FAIRING REMOVE THE HEADLIGHTS AND ALL OTHER FIXINGS , SOME RACE FAIRINGS OR AFTERMARKET FAIRINGS HAVE MARKINGS OF THE HOLE LOCATIONS FOR THE ORIGINAL BRACKET, WHICH MAY REQUIRE DRILLING OUT OBVIOUSLY YOU WONT BE REPLACING THE MIRRORS BUT THE FAIRING WILL STILL NEED FIXING AT THIS POINT

check your coolend level and the flow of the coolend oil ,or there is any problem relating with motor used to pump the coolend oil

Find a manual for it. Sometimes the starter solenoid is not attached to the starter on motorcycles. If it is located under the seat, there's your problem.
