Today's project..change the spark plugs in the bike..

F75gunslinger · Jun 1, 2015

Seat and airbox taken off,battery taken out,and tank tipped up get to the plugs..

This is all the stuff I had to remove to get to the plugs..

View from the other side..

The heart of the beast...the plugs are under the rubber flap in front of the throttle bodies...

All buttoned up again...

While I was in there I put a new K&N filter in it as well. Taking my time...only a 5 1/2 hour job ! Sheesh!

Just got the suspension rebuilt on mine.

Seeing it apart made me wonder if it would ever go back together again.

Amazing what you have to do to service a bike!

Good job.

Fortunately, that is not a job you will have to do very often. Ditto valve adjustments.

I'd really like.....

Cool beans. I'd really like to have a vehicle that I didn't have to depend on and could work on myself with mostly standard tools.

Where is the chrome? Bike ain't got no chrome.

Well let's see now...5.5 hrs X your dealer's hourly shop rate. I'd say
time well spent!

Every 8k for the plugs on this one..I was a bit overdue..still ran good..and the plugs I took out we're decent..but worn! I can't stand to pay out dealer prices for stuff I can do myself...even if it takes time. I like to work on my own hardware..and I like knowing how it works and goes together.

No chrome...all of my goodies are anodized!

Kidding you. I was selling new cars when the plastic "impact" bumpers first came out. I can't count the number of times I heard "It ain't got no chrome!".

Good looking bike.

Impressive....

I'm more like one cylinder one sparkplug

(not my bike, but i have a similar project going)

What kind of bike is that? My that's a lot of time for mostly changing plugs but doing so on some other multi cylinder enclosed bikes may be just as time consuming. BMW's K1600 in-line 6 cylinder comes to mind! But as you did, while all the stuff is apart you take the opportunity to do the air filter, change coolant, etc.

Changing plugs on my Harley and airhead BMW is simply a matter of pulling the plug cap, unscrewing the plug and screwing in a new one, snapping the cap back on. All of 2 minutes per plug. Same for the Waterboxer GSA only a section of each crash bar has to come off making it close to 30 minutes for both. I haven't changed them on my Honda 919 yet but I've *heard* it's a 30 minute job, just raise the front of the tank and Honda's special articulating plug tool reaches them all.

Good job.

Try synchronizing four carbs with three adjustments on each.

OP, I know your pain! I changed the plugs on my old CBR900rr once, & it took me forever. I was trying to do it without removing the tank & the air box & somehow I managed. It wasn't any fun at all. The next time I was at the dealer I asked the service manager what they got to change out the plugs. If I remember correctly, it was like thirty bucks. He told me that yes, they pulled the tank & the air cleaner. So I said fine, next time it needs plugs you can do it!

F75gunslinger · Jun 1, 2015

The bike is an '09 Yamaha R1...I can only imagine what the dealer would charge. I look at it like this. I have the tools and the time to do it, and the mechanical ability, so why not do it myself. I could probably do the job faster now that I know how it all comes apart. First time through I took my time and looked through some threads on the R1 site as well as looking through the shop manual for it to make sure I was removing things the proper way. Lots of small plastic plugs and hoses as well as other stuff you don't want to force apart.

My buddy could tell ya...he had one for years.He upgraded to a Blackbird, so he'll have some fun when it comes time to change his now. The sportbikes are kinda rough, because they want to make them as small and light as they can. So they pack everything into a compact package.

Might be a touch easier to work on that one...

Nice bike and nice photos.

I have the same operation coming with my 2002 Honda CRR954RR Fireblade.

I have to lift the gas tank, open the airbox, take out the air filter, disconnect a cable, remove the airbox plus a myriad of other details I do not even remember. Phew...!

camsdaddy · Jun 1, 2015

I'm pretty sure they hold the plugs and build the bike around them. On my Harley Sportster I simply pulled plug wires and replaced plugs. Sport bikes are little more intense. I work at a shop and when you tell a guy 1.5 or $100 they look at you like you are crazy. More often than not we get the bike the next week partially disassembled. I never give grief. I personally do everything I can for myself and enjoy knowing my bike or gun or whatever

F75gunslinger · Jun 1, 2015

Thankfully for me..I have enough mechanical ability to do stuff for myself. I see different bills my friends have..yikes! I agree that I like to know how stuff works...
