Spark Plugs

VFR love that is a great price. Is that the same plug as the Denso (VNH27Z)?

 

ridervf Cheap OEM spark plug for the 2002 on VFR800? I'm all ears.

 

Sorry I'm not sure. I verified they were correct back when I did the job, checked the gaps (they were correct) and bike continues to run good. Thought I noticed more pep but that's butt dyno talk.
What I presume are the originals in photo are after 16k.

My bike feels faster too, thinking it must be fall's cool, dense air.

sez butt talk is always good shtick.

 

Cool cool......thanks again....

 

Just picked up the correct NGK plugs from O'rilleys for $9.99 each

 

OK three more questions, first-----is there a secret to release the coil connection????
second----has anyone done this without taking off the fairings??? and what if I don't have compressed air to blow out the holes before removing plugs ??? Thanks again

 

Should be just one 8 or 10 mm bolt holding the coil in place.

The contact from coil to plug terminal is spring loaded so they just slide right out.

I don't believe you need to remove any fairings. The front are accessible from between/above the exhaust. The rears require you move the tank as shown in my pic in a previous response on this thread. First to one side, then the other if I recall correctly.

Don't make more of this than it is. Once you take a look you'll see it's all readily accessible. Just put the bike on the center stand and have a couple of socket extensions handy.

Blowing out the holes... I didn't have a compressor to do that either. If you are very concerned a can of spray duster could work.. Or a vacuum. It's a good idea, but even if a bit of some small bit of contaminent got into the cylinder it would likely get expelled through the exhaust valve on startup.

Cool, thanks Man

 

Thanks guys, that can of compressed air is perfect. Have one in the office for my keyboard.

 

Let us know how it goes. Also be careful not to over tighten. The plugs have crush washers that smoosh and conform. The heads are soft and they can be damaged with over tightening. Also- don't do it when the bike is hot - the threads can gall.

Thank VFRL.....thought I might wait another 1000 miles and do my oil at the same time. Seeing that I do 375 miles a week to work and back .that wont take much time. So cold.... tighten loosen them up and re.tighten snug. 10-4

 

Sounds like the perfect time to do a pre oil change and plug seafoam treatment

Oh....I did get seafoam also......cant wait.

 

Just be upwind on a consistently breezy day. Trust me.

Okey..had time yesterday..changed oil.. then swapped out the plugs...just took off the seat straped a tie down to the front of my tank with a rag and the other end to the sub frame under seat..worked perfect....couldnt believe that the plugs were at least 4 inches inside the heads. pretty dang easy.......as soon as I empty this tank of fuel I'll sea foam the fill up.
Just alittle carbon on the plugs thats it. cool cool

 

Are you supposed to remove the little screw on caps off the plugs before fitting? you can see I'm a top mechanic!!

 

sure
