Could be a carb problem or spark plug problem.

2002 ninja 250 idels good runs bad with no power band and sounds like its running on two cylinders but both exhaust pipes get hot,it just doesnt sound like a ninja should,i put new plugs with no change


The power band on a 2002 Ninja 250 does not kick in till you hit about 5000 RPM. The newer 2008 and up 250's kick in about 3000 RPM. There is a website devoted to the Ninja 250 that might give your more background into the motorcycle: ninjette.org You may want to replace your spark plug caps they may be robbing of the spark you need at take off. They simply unscrew off of the end of the wires. They should read 5000 OHM's no higher , no lower. If you purchase new NGK brand plug caps they will only cost about $5 each.

Jet kit,vance n hines,k@n, ran well for 500 mi now runs rough at low rpm and backfires some when downshifting.i put new plugs and fuel filter on it.bike has 5000 mi on it


Jets could be the wrong size, could be the gas, or could still be the plugs. The backfiring is from too much fuel getting into the exhaust and igniting. Running rough at low rpm's is usually a sign of too much fuel as well. I would try adjusting the idle control to see if it doesn't help regulate the fuel to the jets.

2000 Hornet 250: what is the ideal tyre pressure in hornet 250...


NEVER the same pressure on both tyres !!
Usually, rear tyre is larger and/or carries more weight (you), therefore needs a much higher PSI. On a Hornet 250, 600 or 900cc it should be 36psi FRONT and 42psi REAR. - check the manuals.

Rough idle and backfire at low end RPM


Many can cause this kind of problem, such as your jets are starting to clog-up, you have changed your jet-settings, you fuel bowl is not delivering proper fuel amount even dirty and clogged air filter can cause havoc,your ignition timing (magneto) has jumped (out of sequence because it is weaker sparks power), etc.
To start, does it idle properly after a good 3-5 minute warms-up in the past? Check you carb adjustments.
If this happened recently and you have not done or change any settings, try using carb-fuel jet cleaner from STP or Valvoline, etc in your fuel tank mixture when filling-up. Good enough?

Rough idle and backfire at low end RPM


Spark plug or plug wire
After that look to your coil

1999 VN800A runs rough and backfires at high RPM.


if it lives above 4000 ft then it will need re-jetting.
Is it stock or does it have a dynojet kit? If dynojet then you need the DJ130 main jet.

The idle, once warm, is roughly 900RPM and smooth. I have read it should be about 1200 - 1400 though; looked for a manual adjust and I cant sem to find it. Also, the exhaust smells rich. I get about 170...


hello
the idle screw is a bit hard to find but if you were to look at the bottom of the carbs you should find a black knob between the middle carbs. that is the idle adj scew. yes your fuel mileage seems to be consistent with others like yours. thank you.

Engine timing, hornet 250


there is normally marks on the flywheel. sometimes 3 sometimes less. find the mark that makes the left piston sit at top dead centre on the compression strocke and it should be lined up correct. make sure that u are happy before u try starting otherwise it could end up very expensive.
