Question about 1998 Suzuki GSX-R 750 W
When you say "brake down", do you mean "break up"? As in the engine starts backfiring and missing and/or popping and will not rev past 7,000 rpm's? If this is the case, then it's likely a carburation issue. This condition is usualy called "breaking up", as the engine begins popping and loosing power. It will almost sound like it hit a rev limiter. My suggestion is first off, check the basics. Air, fuel, spark. Check for air restrictions and possible air filter obstruction or passing of forign material. Fuel system and filters/restrictions should be checked, as well as the fuel quality. And spark componants from plugs, to wires, to leads, etc. If the issue persists pnce you've got a fresh tune up on the engine, next get the carburators synchronized with a vacuum gauge set. This will ballance the carburators out, and if it's a 1999, even if it isn't the entire problem it's something that's definately long over due. A "carb ballance" is esential for any vacuum opperated carb system, as if the adjustments go out of spec on individual carbs, some may run lean while others are rich. If a cylinder runs lean then it will be the first to start "breaking up", as it doesn't have the mixture neccessary to maintain combustion and it will start by dropping that cylinder, and so-on and so-on. From there if it's still breaking up, go on with further diagnosis and testing of the rest of the fuel system. Things such as clogged main jets, clogged and or stuck carb floats/needles/seats, or even clogged air jets can cause this issue. I would "overhaul" and re-gasket the carbs at this time, as it will save hassle and money in the long run. If you're taking them apart to inspect, clean and re-seal them while you're at it. After carburation checks are complete if the issue is still present I would head to the ignition system. Check your ignition coils, check your pick up lead, etc. After that.... That engine's broke! the Stick
