Hi and welcome to FixYa,

Offhand, it appears that you have an air leak (not a vacuum leak). This could be caused by:

  • loose, detached rubber coupling from the airbox to the air intake;
  • torn, defective, loose air filter/cleaner;
  • improperly sealed cover of the airbox;
  • air filter was replaced with an aftermarket such as K&N and no rejetting, air/fuel mix adjustment and exhaust tuning done.
There are instances when the electrical has an issue and it affects the electronics, specifically the CDI at higher RPMs.

Would appreciate an update based on the above. Good luck and thank you for using FixYa.

Hi, Nick if you have changed your fuel delivery system, air filter size or flow rate, mufflers or exhaust system or a significant change in altitude your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" your not getting enough fuel.
1. Closed to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. Wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, the engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

I would check the jetting by the color of the plug. If it's black, go smaller main. If it's white, go larger on the main. If jetting won't cure it, it probably has a crank seal out. My kid used to race these, and he blew out a crank seal trying to start it with the wash plug in the exhaust. Did the same thing as you're describing. Good luck!

I own a yamaha gladiator ss 125cc bike. done just 3000km on it. if i decelerate, shift down then try to rapidly accelerate again i get sudden jerks from the bike...this problem is intermittent and...


its possible that its valve clearances, but try to isolate at what rpm range the strange sound appears at and when is sputters, the sputtering could be due to a clogged main jet in the carb and the high frequency sound ussually means worn main bearings, but I dont think that with 3000km that would be the problem, try to identify at what rpm you hear it and post again and hopefully i might be able to help

CBR 400 NC29 not pulling through rev range


The carb has serveral jets for different Rpm ranges. If you have a problem with one range, that specific jet is probably blocked. Idle jet, low jet, intermediate jet, high jet. some bikes have more. Sounds like a jet problem to me Run Seafoam cleaner in a couple tanks.

Wont rev out


have you checked your carb? try draining float bowl to see if fuel is contaminated (water,dirt).possibly your main jet is clogged.
