The problem is not havinf the secondary butterflys. They are there to meter the amount if air entering the throttle bodies. When you jam the throttle its pulling a giant gulp of air before there is enough fuel and its falling on its face

Glad you posted this. Having identical problem on my K2. Just started today at a traffic light. Smoothly let out clutch and gave moderate gas. Motor bogged for 4-5 seconds and felt like it was going to stall. Also heard a strange “whoosh” sound. Then ran smoothly as per usual. Weird problem; caught me off guard.

I took the injectors out and pressurized and cleaned them. plus the fuel pump. I also put a universal filter on it going from the tank to the injectors. After that it was fine. When you clean your fuel filter remember there is an internal filter inside the housing unit where the pump site. The only way to clean it is to spray break cleaner in it, shake it. Then dump it out. Do this till the fluid it clean. Dump it out in a cup so you can see just how much dirt is in it. Then spray the inside with some air to help dry it out. The put it all back together.

When mine acted like this I was stumped. We tried several things. Including the fuel pump. But it ended up being the ecu. Bike only had a sweet spot between 5k-8k rpm’s. And only pulled at quarter throttle. And wouldn’t redline . Replaced the ecu and it revs and rides like new. Hope this helps someone out

thesouth50 where did u buy your cpu ? I have the same issue 01 750, no f1 lightchecked and changed nearly every sensor including tps checked both tps with a multi meter had the line in middle in dealer mode new fuel pump plugs injectors, I bought a 2nd cpu used , the same issue both Ecu’s as soon as I plug in tps it’s almost like it causes a short. I can’t rev up at all, unplug tps and I get about 1/2 turn throttle.?

Check your timing, valve guides,and look a great deal into your ignition. I've seen where a stator can provide strong enough spark at a constant rpm but once you move it at all it would try to die. Good luck

Look up on youtube on how to clean injectors. There are many videos on how to do it. Try that and see if it helps. Mine did that and I cleaned the injectors and some other stuff like putting a small universal fuel filter on the line. Also have you cleaned the tank? If it's been sitting it may have rust in it.

Have you put a new battery, stator and rr on it? Sometimes when one of those goes bad it can cause that. What about a universal fuel filter? If it's carb then try cleaning the carbs on it. The jets may need to be cleaned. And if it's fuel injection, then try cleaning them out. I know it's alot but it has to be one of those I just listed. Oh and what about the tip over sensor? Sometimes when the bike falls over the tip over sensor will get stuck. I always take 2 small zip ties and put 1 on each end so the ring does touch the ends. Hope this helps, if it don't then let me know.

@@dirtyred246 so if I took the factory exhaust muffler off my 2002 GSXR 1000 & put a shorty exhaust tip on it the bike used the factory exhaust headers, could this cause my bike down and have a sweet spot in about ⅓ throttle @ the 4200 RPM's? I did take my fuel tank off and pulled the fuel pump which the primary canister was full of black looking crap. I have not ordered the parts for it yet and still have a feeling that that is not going to change anything of how it was running. This 2002 I have was just rebuilt it has only 250 miles on the bike after the rebuild. The heads were milled, polished & all new valves installed. I put a sorrow buddy on the bike because I took the exhaust actuator out. but ever since the rebuild this is how it's been acting. Idles fine and Revs ok, but burns rich. It's only when it's put under a load that it bogs down through all gears. In first gear, I will bog down when I first start to take off but picks up until about 4300 RPMS. It falls on its face between 4300-5000 RPMs and if I pull throttle more or let off of the sweet spot, it's all boggy and runs like crap.
