Any bike experts on here? 2008 zx6r issues

Chasingstatus · 08-05-2018, 01:52 PM

Hey guys, at my wit's end and hoping since I've always had such good luck on here with my z maybe someone could help. It is a 2008 Kawasaki zx6r
So here's the issue as the bike warms up (200°) it acts like it is starved for fuel around 10-14k rpms. So I thought ok, brought injectors to get cleaned at local dealership, put a new fuel pump in the sending unit and new plugs. Same issue. constant 45 psi from the pump sooo not my issue. Bike only has 11k miles on it and for mods it has jumper mod, servo buddy, Yoshi slip on, and ape manual CCT. Any help is appreciated, I am thinking coils or tps sensors? Just tired of blindly throwing money at this thing like a fool.

I used to have a 2005 zx6r but I now ride a 2010 triumph 675, its possible that it could be bad gasoline, I had similar problem on my 2005 zx6r. Pump out the old gas and put fuel system cleaner and premium gasoline, wont hurt to try. Good luck.

Definitely not a bad idea. That's how I clogged the injectors in the beginning is using sea foam lol. How do you like the triumph? All the kawi forums are sooooooooooo dead its lame. Other ppl have this issue then it's just a never ending rabbit hole they all vanish lol

I'd start looking for leaking tubing, ducts, etc. Then I'd inspect/test sensors and wiring.

OhioYJ · 08-05-2018, 08:57 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.

Sorry to hear that Sea Foam blocked your injectors. That's the first time I've heard that happening.
I've been using SF (cars, mx motorcycles, chain saws, lawnmower...) for years and it been awesome, especially for the motors that tend to sit unused for a while or a season or two.
Hope you get that cycle back running smoothly!

Btw, the KTM forum is a total snooze fest as well!

Im loving my 2010 Daytona 675 as it is lighter narrower than my 636 and handles like a dream. I like the 2nd generation 675 as it has the underseat exhaust unlike the new one.

I had to look up some images on that one. Dam, that's a sweet ride!!!

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.

Thanks, Im trying to post a picture but its not working. My triumph is a special edition 2010 version only 300 were made it is crystal pearl white and the frame is powder coated blue from the factory.

It works really well so well that it cleaned out some of the stuff in the sending unit and clogged my injectors. Lol I don't think the previous owner ran any fuel treatment very often so now I'm going to do it every third or fourth tank. Hoping that regular fuel maintenance will be enough

I feel you I like the New naked style old vintage Kawasakis they have out now. The new Z series or whatever. I don't know if they would consider that like a restomod or like an Ode to the Vintage era? Pretty sweet bikes though. I like the Vulcans to

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.
