Re: Gsxr 1000 k2 c46 code

Bugman used to have a website with such information. I wasn't in complete agreement with what he did but it was valuable information nonetheless. He and the site appear to have been abducted by aliens about six months or so ago as it's vanished. If you have a stock system, I suggest that you belly up and follow the Suzuki procedure. If an aftermarket system, I suggest that you look at the Yoshimura instructions for K1/K2 systems. I haven't bothered to check but the Akrapovic instructions may show an alternate approach. There are complications with regard to disconnecting the actuator from the harness.

Would be nice if the Bugman stuff could be retrieved into a pdf or possibly put up here for reference.

Ok, so you should refer to the exhaust manufacturer's instructions on SET valve removal.

Sounds like a job for the Internet Archive!

Re: Gsxr 1000 k2 c46 code

^Yes, that's the Bugman stuff. Nice to see that it's still available, though the aliens still seem to have some of the pictures.

As I recall, Yoshimura has different ways for K1 and K2, if that's what you're referring to. I'd have to check but I think that they want the EXCVA to remain connected for at least one of the years. Bugman showed how to remove the EXCVA by shorting the leads to its motor. The idea was fine but I took issue with the way that he did it (involved chopping up leads on the wiring harness).

Re: Gsxr 1000 k2 c46 code

So in short i have read many different threads on here about removing the lot,i skimmed through bugmans internet archive but it still seems to contradict what others have said about just removing the ecu wire?Can someone tell me if just removing the ecu wire after either disconnecting cables and leaving the rest in or full removal if this will get rid of the f1 light alone or do i need to twist two wires together..kinda just wanna get rid of the f1 light which is popping up from time to time,and once the rain here in the uk stops ill get it inot dealer mode to make sure its the exhaust servo?

EDIT..read more threads,so if i just disconnect cables leaving servo plugged in its the black/brown wire
if i take the lot out its short the servo wires to fool it into thinking its all still there and remove ecu wire for f1 code..
that sound right?

one last thing i need the flapper valve open how is best to go about this if i leave everything in place including cables as the valve seems to be working its just the light i need gone which im guessing is to do with the valve sticking from time to time

Re: Gsxr 1000 k2 c46 code

One way to avoid chopping up the harness is to cut the leads (Gr & P?) on the actuator side of the connector and short them together.

I think that the valve is spring loaded to stay open. So nothing more may be required. For peace of mind, you could wire it open.

Plug the hole where you remove the B/Br wire.

Re: Gsxr 1000 k2 c46 code

ive read so many conflicting comments its all got a little confusing if im honest..obviously hoping as the valve is spring loaded when cables come off it jumps to the open position..

Yes, when cables are disconnected, the flap will be fully open.
