Okay, I know the 'racers' here will probably kill me for asking this, but here goes.....
I have a new 08 ZZR600, and I've heard if you disconnect one of the spark plug wires that this will 'tone' down the power a bit. True, or no? The reason being, I just upgraded from a smaller crusier and I can't quite get used to riding this with the tremendous amount of power right now. I thought maybe with being a little toned down, I could acclimate more with how it rides, etc.
Any thoughts on this, and which to disconnect, where? Or other ideas how to achieve this?
(please don't kill me!! It would only be temporary)

 

disconnecting spark plug wires is not good. yeah you will lose power but damage the motor at the same time.

 

oh yeah welcome to KF

 

The only way to "tone down" a sport bike is to restrict the air flow. In or Out.
I've only seen problems that cause sluggish performance, but nothing on purpose.
So,
The primary cause for power increase during acceleration is the power valve in the exhaust. If you disconnect the actuator cables from the power valve, it'll run like a 600cc cruiser. The normal exhaust pressure will "force" the valve open, and the spring will always push it back.
Problems???
1st: The bike will run rich, not allowing the exhaust pressure to escape freely. That may lead to plug fouling, eventually.
2nd: When the bike is warm, it may tend to stall during deceleration. But it won't really occur until the plugs get gummed up from running rich. probably 2 or 3 hundred miles.
3rd: The FI light will be on all the time, because the actuator is not functioning properly. The ECU should adjust the injector pulse to compensate, but eventually the plugs will load up and foul.

So, Get your **** together, find some other rocket riders, and learn. It's definitely a different ball game on a sport bike, but if your honest to others, they'll be honest with you.

 

if you pull a spark plug wont that cylinder end up raw and disgusting inside because of the unignited fuel? maybe thats only in cars, but it sounds like someone was trying to trash your bike.

 

Can I lengthen the throttle cable, just a tad, in order to give a bit a play with the throttle?

 

It is a carburated bike, so there is no need to worry about the FI light...

Why did you buy the bike if you think it is too powerful? Sounds like a 500 or a 650 would have been a better option for you. I bought the same bike for my very first street bike, and I wasn't that awestruck by it's power. Maybe you should get a smaller bike before you get hurt. Not trying to be an a-hole, I am just saying that if you are worried about your bike all of the time, you may not be paying as much attention to the road. Good luck with making a decision bro.

 

+1 zzrick

dont leave only 3 cylenders running that wil mess everything up and when you go to use the 4th eventually it will be bad

 

god i cant spell today

 

Definitely keep all 4 cylinders operational. Hate to see ya F up a new ride, or any ride for that matter. Use your brain for your throttle control. Enjoy your new toy
