There's a filter inside your fuel pump housing that could be clogged...I tried for months to figure mine out ended up being that...

To change oil remove drain plug under bike, while oil is draining into pan remove left lower fairing and remove oil filter from front of engine. Replace plug and filter and refill, replace fairing.

What it is saying is not f1. It is saying Fl >>> Fuel Injection. The injection sensors have detected a problem in the system. The problem could be anything from a dirty air filter to a fuel mapping error in the computer system. A dealer can hook up a code reader to see what the exact problem is.

Try removing the front sprocket cover most likely around there

Front sprocket's mounting bolt: 127NmRear sprockets mounting bolts: 59NmRear axle pivot's bolt: 125Nm

A couple of things that may sound trivial or silly, but check and make sure your kill switch is in the start position.
Check your fuses to make sure they are all still good.
Make sure that when you turn the key you get a neutral light, if not select neutral and try to start it again.
Check you battery is fully charged, a battery that is below charge won't start a bike like it will start a car.
Did you disconnect any other wires if so reconnect them.
Do you have fuel in the tank?

ok clean up the fuel tank and put a new gasoline, clean all four carburators and spark plug or change a new one,... drain gear oil change a new oil filter,..... change new battery also,.... safe ride bro,......... and enjoy the power,.................

Turn off the ignition, otherwise the ECU may be damaged.
Remove fuel tank cover, seats, battery compartment bolts.
Pull out the battery tray slightly, disconnect the negative terminal wire first.
Everything else is straight forward.
Hope that helps.

don't let it fool you. sometimes depending how old your battery is will make you think it is not
charging . your bike charges just enough to keep yourou battery at top charge and that is it. so
then you shut your bike down and after a short time you go to crank it back up and it wants to
but just dose not have enough charge to do it, that is when you know your battery is no good .
even if you full charge it and then ride it may be fine , but the lights are on all of the time and
touching the brake will take that full charge a way quick if the battery is no good . 2 years is pushing it , and some will last longer ,but trust me when I say this . good luck.

clutch is either adjusted wrong or it time to replace it sounds like its not disengaging

Hi.

Check the kickstand switch. When it is faulty it will turn off the engine when you put in gear. The switch is tested by jumping it.

0.7 - 0.65 mm

you need to remove the tank completely once you have it of the plugs can be accesed use a tube spanner after removeing the plug leads

i cant tell if this is a Honda... but if it is, they are notorious for the plastic connectors melting and it could cause a short and if it does than your voltage regulator system will be affected also and not charge the battery properly.

Try swapping out with a new oil pump or a known good one.

hi buddy easy to do remove seat unscrew bolts by steering holding the tank in then tilt the tank up and then you will see the 4 coils easilly pull these off and get a spark plug socket and ratchet and losen them off and pull out also in the socket will be a rubber this helps pull the spark plug out then when you rwtighten the new ones tighten them but dont overtighten it buddy then re install it back together any more question get back to me

i would check the fuel supply, valve, fiter and carb bowls. if when it runs it runs fine, this is the most likly problem

It has been a long time since you changed the oil and oil filter, right? Extremely dirty, gritty oil can cause the clutch to grab as you describe. There is a $25 get-me-by fix and a $50 do-it-right fix. Th $25 get-me-by fix means you drain the old oil and put in new oil and a new oil filter. The $50 do-it-right fix means you do the $25 fix then ride the bike for an hour and do the $25 fix again. The 1st oil change gets rid of 75% of the bad oil and grit. The hour ride and 2nd oil change gets rid of 95% of what was left after the 1st oil change. There is also a $30 fix and that is the $50 fix but without a second oil filter. The drain plug is on the bottom left of the gearbox. The filter should be at the lower back of the gearbox. Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell. Use Kawasaki brand oil filters. Aftermarket filters often fail.
