Guys, need some help please. i need to bypass the clutch switch on start up. i have read that, pulling in the clutch when you press the statr button send a different map to the ECU saying that the bike is starting. is it easier just to put a push button switch on the bars to replicate the clutch swich, (ddint really want that) or is there another way,

thanks in advance :biggrin:

Not all manufactures have this feature.....

Some people do it for sport clutch levers as it doesn't accommodate the switch.

I set this up on my bike before, took some searching. I pulled the relay out because I was throwing a code due to my secondaries being out of my ITBs. I was thinking along time ago just to run wires to the starter button too alleviate the whole issue.

I don't know about safety being overrated. I've seen people get very severely injured while catching a race bike falling at walking speed because the clutch safety switch was disabled. A moment of simple clumsiness and a dropped bike most times, or a broken leg gored by a solid mount foot peg another time.

A carefree attitude about an extremely dangerous sport is a really bad idea.

Well, basically, from looking at my ECU wiring diagram, I should use the wires on either side of the starter switch and connect those in parallel to the coil of my relay, and then connect in parallel the wires from either side of the clutch switch to the switched side of the relay?

Then, for the neutral safety feature, I can run a relay in the positive side of the wire coming from the starter switch to the original relay, which is activated when the neutral light is lit.

I believe that would work to either start the bike in neutral without the clutch depressed, or I should still be able to start the bike in gear with the clutch depressed. Right?

Lol, jk. I think I need to connect the wire post starter switch to the relay that is enabled by the neutral light. That output then goes to activate the second relay which acts as the clutch switch. I believe wiring this way I can start in neutral with just the button, or in any gear with the clutch depressed. Attached wiring diagram.

Old thread but not that easy.

Your solution is the same as jumping the wires together. The ECM always thinks that the clutch lever is pulled back so it neuters the engine performance.

It is a nanny part just like the sidestand switch. Worthless unless you forget you are in gear when you try to start the bike, then it might be worth quite a bit if it saves you from crashing or dropping the bike.

Well, you guys know (because you put me right! ;) ) that my GSXR has some sort of failed neutral switch so that it won't run at all unless the side stand is up.

You have to sit on it to start it, anyway (or rear stand).

Honestly, I like it like that. Never had an issue, and when I come to a stop, no messing around with extra button presses, just drop the stand and the engine stops.

Get in the habit of just cranking the bike to start and I am sure you will end up with many dropped bikes.

My 893 'Blade is like that. Won't start with the stand down (or without pulling the clutch in either). You can put the stand down once started though. Sit on bike, stand up, pull clutch, hit the starter.

Apparently that's how Honda designed them originally.
