Sputtering at low rpm ttr230

The bike sputters at low rpm, if you get it more throttle it runs great, but just slowly moving in the woods it sputters. I changed the plug and cleaned the filter but nothing seems to change.

Run some carb cleaner through the tank. "Seafoam" has a real following. It could be that the jets are crudded up, especially if your bike sat some over the winter.

SOURCE: 2003 night train fxstbi starts fine but sputters at low speeds.

It sounds like it's running a tad lean on the low speed circuit. Since it's fuel injected, you'll have to take it to a dealer or maybe an aftermarket shop to have them check the computer's fuel map setting.

SOURCE: I have a Kawasaki Ninja,

There are adjustments on carbs for low speed air intake (air mixture screw)find out factory settings and reset that mixture.Sounds to me like those adjustments are out of sink.If so the bike will run very bad from idle to about 1/4 throttle then run great from there up to full throttle.this definitly sounds like carb problem.

Vanguard V Twin 18 hp. monted in Cushman Motor scooter, runs great at W.O.T and at on quarter throttle, misses at range inbetween


Sounds like your carb needs the fuel/air mix adjusted..uses all the gas at high speed but has excess at low speeds...find your adjusting screw and at med throttle slowly screw it clockwise until the engine starts to sputter then back it out until it starts to sputter again then continue to do this until you reach ideal mix where it runs the best it can..then go slowly through the throttle up and down..when set..unjust your idle speed screw to your ideal idle speed..if this dies not fix ..carb will bed cleaned or rebuilt. Good luck.. Note always push or pull your throttle handle slowly to position avoids gas load up causing sputter and backfire.

Motor chokes and misses under moderate load and loses power


Sounds to me as tho it might need a carburetor adjustment, providing there is an adjustment screw on the carb. Sounds like the engine is running a bit lean. Did this problem occur right after the carb cleaning, or was it there in advance? Is there a fuel filter that might be clogged?

Above 9000 rpm skip/sputter/gear slip.


I would check the oil first, when your riding at 9000 rpms the bike working harder, if your low on oil the basics is for malfuctions. Check all your fluids, coolant would be the next one. If its sputtering, possibly the air filter could be dirty and need changed.

Sputtering at midrange rpm somtimes


Perhaps I'm too late and too long winded! But to answer your question about the fuel pump, yes the pump failure mode could be gradual. But as for your "sputtering" engine the root cause could be related to the fuel or ignition system. For clarification I have a few questions. (1) Realizing this may be an intermitent problem, can you make the engine sputter if you rev the engine with tranmission in park? If yes, this reduces the probability of the sputter being ignition related. (2) When you do rev the engine do you get full rpm's (> 2000rpm) or does it seem choked/limited? If no, your suspisions maybe correct and your engine could have a fuel system problem. (3) Or possibly the sputter only occurs/worsens when the engine is loaded? You can sufficiently load the engine by applying the park, service brake pedal, shifting the transmission into drive, and then slowly applying moderate accelerator pedal. It shouldn't take more than 25 to 50% of accelerator application to safely load the engine.

Two possible solutions: If the engine sputters with the transmission in park or you just don't trust the fuel pump you might want to check the fuel filter first before condeming the pump. The alcohol content in fuel could have cleared enough debris to plug your 3 month old fuel filter. You should be able to blow through the filter without much effort. When the fuel filter is clogged it will fatigue the pump and can lead to failure. It could also be poor fuel quality though. (2) If the engine sputters loaded check the ignition coils and module. One way to check a coil is to disconnect a plug wire set before trying to duplicate the problem. If the engine sputters worsens with a wire set disconnected that coil is okay. You will find the culprit when the sputter doesn't change with a plug wire set dis connected.
