You'll have to pull the tank. It's not hard. Should just be a couple bolts holding it on. Do you have a repair manual?

all i have is the stock manual it sucks, i've had the tank off plenty but not the air box wich covers the plugs i've never really taken it apart past there. how long do plugs usually last? and what do you think it cost me for a complete tune up?

I replace my plugs every year. I run NGK's...and get them at about $9 bucks each. Tune up will cost you a few bucks...but it's a necessary evil.


Look on eBay for a service manual for your bike. It'll really help...it explains all that stuff.

I like to do most of my own work. Unless its outta my league. But I do simple stuff...oil, plugs, etc.

Tune up could be talking about a number of things....plugs, air filter, wires, fuel filter, etc.

You could also go a step further and swap out the fork oil and seals too. As well as checking valves, changing your coolant, etc.

I erringly got an '03 service manual at home that won't work for me. If I haven't given it away at another forum then I'll send the stuff to you. Drop me a PM with contact info and I'll get back to you when I can.

Plugs are simple. I have a 00 zx6r but they should be really similar. 4 10mm bolts on the tank 2 in front and 2 on rear under driver's seat. unhook the gas line and remove the tank. The airbox has 2 holes on the top with a rubber plug in them. Remove the plugs and there is 2 10mm bolts in there. Remove them and the 6 other 10mm's around the box. The box then pulls straight up and back. Then there will be some vacuum lines in the way, label them with a white out pen then remove them. You should then see your sparkplug coils and harnesses. Remove the harnesses and pull the coil and wallah there is the plugs. Like I said it should be very similar so good luck.

I buy my plugs at advance auto they are ngk cr9 and they are $3.50 each.

Download the free manual on the sticky thread from the technical help forums. It takes a long time to download but definatly worth it!
