I'm no mechanic... and I didn't stay at a Holiday Inn Express last night... but I decided I didn't want to pay someone to do this for me so I drug the toolbox out, dusted it off and went at it. This isn't meant to be a "How-To", really... just a few pics that might help someone out if they decide to try it. I don't have a manual yet, so it was "hunt and peck" for the plugs and how to get to them. BTW... you do not have to remove the air box to do this :2cool: Just remove the gas tank, both filter housings, the right-front and left-rear chrome covers on the heads, the two pieces of plastic that wrap around the gooseneck (?) and go for it. The owner's manual that gathers dust under the seat recommends gapping the plugs between .024 and .028 (I gapped mine at .025)

The center spark plug on the rear (closest to the seat) cylinder is the easiest:



The outer spark plug on the rear cylinder is behind the left-side chrome cover:



You can get the right-front chrome cover off WITHOUT unbolting the rear brake reservior from the frame... try a few angles and it'll come off.
The center spark plug on the front cylinder is a little harder to get to. Good thing my Dad gave me most of his tools a while back:



The swivel adapter he bestowed on me came in very handy today. Thanks Pop :D



You can get the center spark plug out even if your socket won't hang on to it after it's loose. Look just behind the outer spark plug and there's access to it:



Both outer plugs are easy to get to with a socket extension:



I found another place where coolant was leaking, too :verymad: I'll post it seperately with pics.

Good show. I was cursing that center front plug, but after the appropriate cursing, it can be done.

4 spark plugs ::)
Then why did I buy two????
 My vast motorcyle mechanical training and background, I guess!!
and I paid ten bucks apiece for them at the dealer
...I bet a better price could have been found somewhere like direct line, our sponsor here, for 7.45 each!

actually a swivel is not needed,but various short extenions are for the front and rear inside plugs.

I've always liked to perform my own maintenance and service work, looking at this pictures is reminding me of trying to work on new cars. Nothing is going to be easy anymore. :-\

This link sends you to buy the plug they recommend to correct the situation if the standard plug becomes too wet. the link for the standard plug which I have never noticed as a problem, the link to the same site but with the standard plug is,

This second link is for the recommended plug to use if your standard plug is apt to overheat.

Hey I learned something too. I never knew that chrome piece that covers the spark plug can come off, so now I'm going to paint it!

This is a good thread with pics for anyone going to change their spark plugs for the first time like I did last night. I have 9000 miles on the bike and the manual says changes the plugs after 7,500 miles.

My plugs didn't look bad at all really. They were a little white so I guess I could have went with the cooler running NGK CR9EK's but I stuck with the Standard CR8EK's. But I'm not running too rich which is good.

3 of the 4 plugs are very easy to get to and it's no big deal. The fourth plug (the one closest to the forks) is a bugger however. Just not much room to navigate in there (see attached pic). You definitely need two extensions (one short & one long) as well as a swivel to get it loosened & retightened.

I do not know why you would have to change plugs every 7500 miles, I checked mine and they look good so they stay, I have 18000, my plan is to change around 25000 unless there is a problem. But as good as these look I don't expect there to be any issues.
