Okay so I got a 03 cbr honda 600 RR. Originally I was going just going to replace the air filter. I figured since I had already got most of the plastics off and went as far as I did, why not replace the spark plugs! I was going to take it to the shop to let the dealers do it but I'm not too fond of getting over-charged for a job I know I can do. So, I just removed the gas tank and that's as far as I've gone. I plan on finishing it this weekend! So what I'm asking from you guys is how much further do I have to go? Is it right under the air filter box? I'm excited and nervous! haha... Thanks guys and any suggestions would be nice!

 

Not sure bout the RR. On the F4i yup right under the airbox. I suggest using on of the overflow hoses to retrieve the plugs, and to reinstall them. That reduces the chances of crossthreading.

 

cross threading? No clue on what that means?

 

Just installed new spark plugs on my F4i.

You need to get the air box off and there they will be. Nothing complicated about that. Used a magnet to pick the old ones out and put new in. Torqued them down to about 10lbs/ft.
Confirm the torque specs with the manual, unlikely they are different, but you never know.

Ohh yea, it's recommended to use some grease on threads of new plugs to make next change easier. Can't remember what the grease is supposed to be based on though.

 

Thanks man, I was pretty sure it wasn't all that bad... Torque them down to about 10lbs/ft? Want to explain that one too me? I have a manual for the bike aswell. I'll def grease up the spark plugs thanks!

 

The main reason why you want to grease the spark plugs is to insure that you can get them out without problems the next time. In worse case scenario you will strip the thread and it's a few hundreds of $ and some time without the bike.

Yes, torque is very important in any mechanical applications you come across. Not enough torque and something will fall apart; too much torque can lead to a premature wear/overheating. I always torque anything I'm dealing with apart from the fairings (thanks to low vibration our bikes produce). Buy yourself a torque wrench (the price goes from 15-300$). I've purchased one for about $50, and it accommodates all my needs. The way it works is very simple and intuitive. You set the amount of torque you want to apply and the wrench will either stop applying any force right after it reaches the set amount or will let you know that the amount is reached.

GL to you on this and let us all know if you have any additional questions.

 

Improperly starting the threads. Also leading to more time and money.
