There is really nothing to it. It's been awhile, but if I remember correctly, all you have to do is prop the tank up a little bit to get to the back one. The front plug is right behind the front tire. Pull the wires off, get a spark plug socket with a little extension and the rest is easy.

You do not need to remove the tail. I did not have any problems. Just have to remove the two screws so it can pop out a bit when the tank is raised. thats all.

That's a +1 there mang., I did the samething, removed the 2 side screws right at the fuel cell, put a 100%cotton rag between the fuel cell and the cowl and raised slowly...:clapper
Side Bar- Chuck... Have You not got the messages that I've Called!...

18,000 miles! Wholey CRAP Dude! :eek: TXRC51fatboy is right, You WILL be amazed once you've install NEW Spark Plugs!... I change mine like every 4,000 miles, 6,000 at the most!:clapper


Spark Plugs set at 13ftlbs.... DO NOT Over Tighten the plugs!

I have to say though man, I'm really concerned about you doing this JOB.... When you are asking about how to do it or "Tips or whatever the case maybe.. My god bro., there spark plugs...;)

IF You don't have one (sounds like you don't:rolleyes: ) Get Yourself a HONDA OEM Service manual!

Peace Maverick

10mm ratchet wrench and blow dust off before removing the plugs.

btw it does run funny at 18,000 miles +

i'll pick up some plugs over at CycleGear in town.

Not to beat a dead horse, but I recommend going crazy with the compressed air before plug removal. There was more than just *dust* in my plug holes, and I cringed to think that all of that debris would've fallen into the combustion chamber had I not blown it all out. Can you imagine the damage!?

Yeah, so...blow it out. :D

One last thing you need to is when you tighten the spark plugs, loose them back up and retighten them again. That's why they come with crush washers. Spark plugs have a bad habit of coming loose from the vibration of the motor. Good luck bud.

You did you valve adjustments at the same time? Good work.

I'm doing those right now, and it's certainly a bit tricker than changing the plugs!

Send them to Dan Kyle and he'll turn them in 3 days usually. You won't believe how good they work after he does his magic on them!:rockon

IIRC when I had my RC apart after I wrecked last time, it seemed to me like the tank would be a bitch to prop up because of those short ass lines underneath that attach to the part that you prop up. Maybe my shit is just routed weird or something but that rear spark plug is going to be a mother****er to replace if i am right :(

Don't worry, it's not that bad. Yeah the lines are kinda short and the tank won't go up to far, but there is space. I didn't think it would be possible either, but I started working on it and managed to find the ratchet and extension that fit. You might have to go through a little trial and error, but it's pretty easy.
