Bogging down is most often a fuel pump filter issue. Check the flow rate per the service manual procedure.
I tested the bike with a fuel pump that had a filter which was cleaned. I even saw that filter by myself and that repair shop borrowed me that one, didn't fix with it.Bogging down is most often a fuel pump filter issue. Check the flow rate per the service manual procedure.
Could be the strainer, he removed the bottom of it and I saw a thing that looked like a coffee filter 😅"I even saw that filter by myself"
That sounds like you saw the strainer, not the filter. It's difficult to see any part of the main filter element.
The ultimate test is to measure the fuel pressure while you're riding & bogging. But that takes a bunch of hooking things up. The flow test is much easier and is usually definitive. Fuel injector cleaner will remove injector deposits but it will take several tankfuls of gas to see results.
The second most common cause of bogging/rev limiting is a problem with the secondary throttle system, either they aren't opening fully or the secondary injectors aren't working or are clogged. Your video sounds more like that. You can watch the injectors cycle when you turn the ignition on. It's also possible to swap the primary and secondary injectors but the screws that mount the fuel rail have a habit of sticking in the throttle body. But I don't know why the secondaries would clog and not the primaries, so bad electrical connections would be more likely. However electrical issues should cause a fault code. You said that you have C28. I can see the red fault light and, barely, FI being displayed in the video. You have to get rid of that. You're operating in fail-safe mode.
That could explain it, because it really feels more like of a rev limiter.The service manual is vague on exactly what happens, saying only "FI system is provided with fail-safe function to allow the engine to start and the motorcycle to run in a minimum performance necessary even under malfunction condition." and "But, the engine running condition is not complete, providing only emergency help (by fail-safe circuit)." That could easily mean a lower rev limit.
Unless you removed the secondary throttle shaft, you should be able to see it turning. I think it goes through a procedure on startup to determine the limits of travel. No butterflies probably screws that up.
The filter is on the top, not the bottom.
No, but would faulty one drain the battery dead?have you tried replacing rectifiers ?
Yes to both of them. Could the problem lay in the ECU then?I'm unfamiliar with the Healtech. The C28 will automatically go away if faults in the secondary throttle are corrected. So I don't see why that shouldn't also happen with the Healtech. Does it connect to both secondary connectors?
I actually know the reason. My local vendor sold me the STVE-01 version which is incompatible with my bike, it should be the STVE-10 version. They had the incorrect eliminator up for sale stating that it fits my 07 GSX-R. Have to order the correct one and return the incorrect one and wait for another 3 weeks.How about in the wiring to them? Early on here you said that you were fiddling with it.
Yeah it's strange that the connectors are exactly the same, but Healtech confirmed in email that STVE-01 version is incompatible with 07 GSXR 🤷♂️It fits. It just doesn't work.
I have the original exhaust with GPR mufflers and the catalyst is replaced with Y-pipe. I thought about this and when I give full throttle, I don't see it moving but is this the condition where it should fully move? When I turn on the key it moves just a little bit but a Suzuki service guy said that it works if it even moves a little bit? But never seen it fully move when revving.What exhaust do you have? The EXCV valve will choke the bike if it doesn't fully open.
