GSXR 1000 Asphalt RPMs |
Lead | |
|
For those of you running a GSXR 1K on asphalt what RPMs are you turning them?? The low, in the corner, and high, down the straitaway, RPMs would nice. All
help is appreciated

i just about hit the limiter when i start to brake for the turn.

do you happen to know what that RPM is?? I will also try to find in on the internet Thanks

wired right?? | ||

2001 Gixxer 1000 will hit the limiter at 12,200. That is with a stock ECU, if it is wired correctly. The clutch needs to be pulled in, on the bikes, for
the motor to start. Early versions of cut down harnesses solved this by wiring it so the ECU thinks the clutch is always pulled in. The problem is THEN your
revs are limited to 11,900 RPM.... AND you have a tame ignition map.

clutch bypass | ||

I can't remember the wire color but if you add a 100 ohm resistor to (I think) the orange/white wire and connect it to the brown wire you can bypass the
clutch safety without going into the "limp" mode.

Wrong, a 100 ohm resistor won't work. I think you are confusing this with the anti theft override. I put switches in most wiring harnesses I cut to
simulate the clutch being in when starting. You just flip the switch off after starting. If you don't switch it off, you will remember after the first
straight when your rev limiter hits early. You can also add a relay in the circuit to automatically make the engine think the clutch is pulled in when you hit
the start button but you need a diode in the circuit to make sure the relay doesn't stay engaged when you release the start button. The residual voltage
coming from the ECU can keep the relay engaged. I normally go with the switch option for most people so I don't have them calling me up when they have a
starting problem and want me to troubleshoot over the phone. Flip is right about RPMs. 05 and 06 redline at 13,300. Earlier models can go higher with a Yosh
ECU box but anything over 12,800 and you will probably float the valves. 01 to 04 valves and valve keepers are a weak link. Turn them higher that 12,800 and
you will break the tip off of the valve. It will drop and at the best, require a new valve/seat. At the worst, holes in the engine.

gsxr 600 | ||

Ron,
Do you know if this holds true for the GSXR 600 also? I am pretty sure that all my cars just have the wires connected to bypass the clutch safety switch, and I don't think it is running in limp mode, after all it's pretty obvious when you do get the FI codes and it goes limp. |

still runs good | ||
|
The clutch in mode is not a limp mode. You can still make serious power at 11,900 rpm with the "tame" ignition map. I ran my 1000 this way for some
time (in 2002) until we discovered what was up.

600, 750 and 1000 | ||

The wiring is basically the same for the 600, 750 and 1000. I have made the same mods to all three models (and years from 2001 to 2006).

dont make it harder than it needs to be. | ||

. the black wire for the clutch goes to 3 places.
1. clutch lever (grounds the wire when pulled) 2. start solenoid 3.ECU (computer) the start solenoid needs it pulled (grounded) to start. but grounding it causes a "zero map" at the computer...... so what to do? 1.cut it at the computer so the computer can NEVER get a grounded signal. therefore operates in full function always. (unless its actually in neutral) 2.ground the wire to the start solenoid so the car can start. so..just to re-itterate. give the ground to the solenoid but not the computer. simple. no extra buttons switches or tom-foolery Sorry I didnt chime in sooner, I havent been online much. have fun out there and be safe Jeff B |
