Question about 2006 Suzuki GSX 750 F (Katana)

1 Answer

Powerloss when in gear

I had just recently had a carb clean a year ago, and an oil change with filter and 2 cap assembly were changed along with the fuel strainer a week ago. Had the problem prior to the tune up and everything worked fine after the tune up for 2 days. Again this morning, warmed up bike and set the choke back and idle was fine, put it in first gear and pulled throttle back and RPM's got to 4k and then major hesitation and then the engine dies. Checked the simple things like air filter and oil and fuel. I don't know if it is electrical and I should replace the last 2 spark plug cap assemblys or if I need to take it in and have a full carb clean again. Please Help

    have you checked to be sure the vent on the tank is not clogged? the vent allows air to enter the tank as fuel is drained from it to the carbs. if vent is blocked, then gas will not flow at the greater demands as throttle is increased.



    vent should be under the gas cap. try this:

    1. open the gas cap

    2. start the bike

    3. let is warm up

    4. turn off choke

    5. drop in first gear and try to go.

    6. if bike wants to go, then vent is blocked somewhere

    7. if bike stalls (like it has been doing), then its not the vent, but at least we eliminated this.

Sounds to me like a jeeting issue with the carbs. If you have an aftermarket pipe then I would reccomend haveing the jetting changed in the carbs.

Replace the needle and seat in the float chamber. You can try cleaning the carb again this time using lacquer thinners, the only stuff that really cleans the gum that gas turns into when left standing, but consider a new carb kit.

89 Wagoneer drives rough


The thing to do now is a fuel pressure test pump could be weak just a few pounds under the recamended pressure will do that weather its mechanical or electrical . Is there a filter in the carb. wear fuel fine hooks? If none of this is an issue at least you can eliminate fuel deliverly as the problem.

The car is sputtering at high rpm


Hello, I would change the fuel filter especially if it's never been changed to your knowledge and if the car runs great up untill 4200rpms. If the filter is starting to plug then it will fell boggy and possibly jerky because the motor is being starved for fuel.
