Any bike experts on here? 2008 zx6r issues

OhioYJ · 08-05-2018, 07:57 PM

Any codes at all? I assume you aren't lucky enough to have a self diagnosis mode? On my R6, I can go through a diagnostic mode and cycle through sensors and solenoids, and see what they are reading.

My R6 is throttle by wire, which I'm assuming your ZX6R is. On my bike it has two TPS sensors, one for the throttle cable, one for throttle bodies to monitor the throttle blades. They have to be adjusted within a certain range of each other. If they are are out at all they set a code immediately, if they out too much, the entire throttle system shuts down. Either way there will be a spec for the TPS sensors and they can be checked with an ohm meter. Even if you don't have a spec, sticking an ohm meter on there may tell you something, the transition should be nice and smooth in both directions, on both sides.

On the R6 the main line that goes between the tank and fuel lines is easy to kink, and once it does it collapses. Perhaps something to look for on yours?

A coil on most modern bikes usually sets codes too, but not always. Does it feel like it a miss, or just it running out of fuel?

I saw the slip-on, no fuel management device on this right? I had my Power Commander shutting off my lower injectors once thanks to a firmware glitch, made my R6 sound almost like a Harley for a moment, luckily it didn't happen at high RPMs.

I've been considering a street bike for a while... just to cruise around on once In a while. Looking at the Kawi Vulcans. Either 650 or the 900.

No that's the craziest thing not one FI light has been set off. I wish these systems were just as finicky as OBD2. The fuel line being kinked is extremely common. the TPS are both like $114 together and then throttle body assembly used is like $50. Turns out a good multimeter is just as good as a scan tool with a car. I 100% experience the Harley sound when my injectors were clogged. I didn't know if I bought a power commander if it would hide the problem or fix it... all I know is this self-diagnose mode you're talking about for an R6 sounds pretty desirable Currently.

No, a power commander won't fix your problem. You need to determine the root cause first. Unfortunately most of what I know is limited to Yamaha, as that's what I have. On my R6 codes are stored, similar to an OBD II system even if the light isn't on. Really doesn't sound like you have much to go on. Have you been able to locate a FSM online or anything?

Yeah, I'm going to try to buy a ZX10RR tonight and I think I'm going to grab a manual. These kawi forums are sooooooooooo beat now. I definitely appreciate all the info. I could see what voltage the coils put out to determine if ones performing lower than factory's standard?

Usually you check coils by measuring resistance across the primary and then secondary coils. There is typically a spec in the manual for this. To bad its not a GSXR, I bought a set of GSXR coils on whim (well educated guess) for my super moto hoping they would work for a conversion, but they wouldn't clear the frame.

What's the jumper mods? Did the bike do this before the mods?

I jumper is basically connecting two wires to get a European to and that didn't meet American Standards for emissions. no this is all pretty fresh within the last 200 miles or so. All the mods have about 6k on them.

Yeah it's crazy how many of these parts fit both bikes. I ordered a fuel pump from a GSXR because they said they couldn't do it at my local dealership without buying the whole sending unit. $50 vs $391. so I pulled it out and swap the pump out just like I did all my Z cars and everything else I've ever worked on. Had the Mitsubishi part number right on the pump
