now how the hell am i supposed to get the damn spark plugs out... **** man my gsxr was alot easier than this.

 

Should only need the correct size spark plug socket and a short extension. I used an adapter on the socket so I could use a 1/4 inch drive extension - the skinnier extension makes manuvering the plug out easier. Other than that it should be no sweat.

 

thanks bro, any idea on the socket size?

 

They are tough to get out, eh! As weird as this may sound, the best tool to get them free is the one that came in the Honda tool kit. It has a built in wobble feature that can solve all the problems you might have. When I changed mine I would not have been able todo it without it. I went in through the front by dropping the radiator out of the way. It was hard but looked easier than removing the airbox. I was prob wrong though. It was so difficult I swore I would sell the bike before I did it again. I guess I am a liar though, because it's that time again, and I'm not letting go. Anyway the Honda tool kit has the ticket to solve your problem.

holy hell!! I'm just starting this endeavor as we speak. I tried using my plug socket and an extenstion first so now that I have it dropped in the hole, I'm not sure I'll ever get it back out again. My bike didn't come with a tool kit when I bought it but I got one from a dude I know. I really hope it has the right tool in there.

Here's an odd one: the reason I'm doing this spark plug swap.....when I was riding today, all of a sudden my bike sounded really loud and lost hella power. after some investigating, one of my plugs backed itself out[:@] How the hell can that happen??? When I looked at the plug that came out, it was bridged (is that the right word? it didn't have a gap anymore). could that have caused it to back out?

 

chpanther69 - I believe it's a 16mm socket for the plugs, but I used a 5/8 inch spark plug socket which holds on to the plug. If you drop anything down there, a magnet or mechanical fingers will retrieve it.

ibkevman - that's wierd. I would make sure the plugs are correct for the bike. If so, get a new set ( usually the iridium plugs come factory-gapped ) and install them to the proper torque.

Also, do yourselves a favor, and get the Haynes Manual, everybody....or download stephygee's on-line Honda manual. Better yet, for 60 bucks you can order the real manual from Honda.

 

Good info... I have the 929 service manual in pdf format (the 700 page one). 59megs in size. Great book.

Also, I never trust factory gapping. Besides, what if that number 3 cylinder (picking an inner cylinder randomly) is burning just a little rich? Wouldn't you want to compensate just by adjusting the gap every so slightly. Silly little tricks like this, help to optimize fuel, etc...

I dunno, but the spark plugs tell so much of a story about how the bike runs, in addition to grabbing a handful of exhaust fumes and taking a wiff.

 

what plugs do you all use in the 929? factory recommends denso iuh27d but the ones I pulled out are NGK imr8c's. also, any place better than others to buy them from? I try to avoid stealerships if at all possible.

 

I got my NGK Iridiums at the Honda dealer - Ithink they were like11.25 apiece. I think the cheapest I saw em online was maybe 9.50 or so. I changed them at 9500 miles, man what a difference they made.
