Thank you for supporting the awesome VFR 800 community!
This a great instructional video as well as letting us experience how to maintain this particular beauty! I love how you used the interior detailer spray then transitioned to bungee chord. Better than having a can or something proping it and risking knocking it off.
This is the only video where the frame and lighting isn't botched to change sparkplugs....thanks for the video!
For deep reach plugs i use a piece of rubber hose that fits snuggly over the plug to insert them, that way you don't need to drop them in and risk altering the plug gap, you can also start them off the same way and risk any cross threading.
Or just get a proper spark plug socket.
@@GPz84 I almost think the rubber hose is a better solution. If the plug socket comes loose from the extension and drops into the hole along with the plug, it's just that much more weight on the plug when it hits bottom. The hose also allows more feeling when starting the threads to keep from cross threading.
I cant helieve he dropped them in either. I like this tip, even more so than using a spark plug socket that has a potential for the plug to slip out. Unlikely but in tight quarters like this bike, im taking all precautions to not damage the plug or top threads
Good vid apart from showing the incorrect way to install spark plugs " Never drop a plug onto its hole" bad practice !! thread damage to plug & head can occur ... This is why a proper plug socket has a rubber insert to hold plug secure before attempting to start thread ... keep up the good work.
I have been watching you for a long time now you are doing a great job keep it up man 💯
This is what I am talking about! Great educational piece. 👏
Well done and thanks for taking us on the journey Hero.
Now go and purchase a Blackbird so I can learn about on that. 🤜👌
Excellent and easy to follow video. Cheers. Everything went well until the last spark plug (rear left hand side) rounded screw which i managed to hammer it off with a screwdriver. The £15 ebay pair blanking kit was easy aswell.bike fired up much quicker
Thanks again for sharing, it helps alot and saves me money😂
Hi there,
Thanks for the video.
I've just ordered myself a set of plate for the pair valve deletes.
I know there are two pipes one left one right going to the airbox. When you've removed the pair valve itself, there is also a secondo tube underneath, how do you close it?
Thanks
HI i have a question where can i get the block off plates after removing the pairing system is there a link to a site to get these ,,your vids great cheers John
I just came from your video from 4 years ago about the Suzuki drz. Can you talk about the klx 300sm, we need an update
Do you have a link where to buy pair valve block off plates?
Honda shud make a new vfr bike. I think u should also do some mods to ur vfr.
Where can I find block off plates for the pair system? I have the same yr vfr800 and can't seem to find block off plates for my bike.
how does deleting the pair system help the bike? i also own 2009 vfr and so far i only did snorkel/flapper mod
Nice work! I've plugged the PAIR valve from the air box (and it did help the bike run smoother at low speeds and small throttle openings), but is there an advantage to removing it? Other than tidying everything up?
Nope. Just declutter underneath and an insignificant weight savings.
Where'd you order the block off plates from?
What's the interval for spark plug replacement?
It actually does say "12 Nm" for the spark plugs (2002 Service Manual)
Ah ok, I only have the owner's manual, on page 103 it says to tighten 1/2 turn for NGK. Good to know the actual number is 12 nm.
I know your a honda guy looking to get my first cbr 600rr.. but I was told that 2007 vs 2008 has different. 08 is supposedly faster/more reliable
And 08 apparently has a different rake? Is this true? I'm not a honda guy can't find much on it, if it'll even make a noticeable difference or not. Is the rake in the frame or?
Nice 👍 but I would do something about that rust on your oil pipes to and from your oil cooler.
Yep, I'm going to use steel wool on them, should clean right up.
The 8th gen VFR torque specification is 12 lbf-ft (16 Nm) for the spark plugs.
Did the exhaust pop more with the PAIR delete?
What's your mileage at ? Manual says to change the spark plugs at around 50 000 km. Is this a bit early or are they due at that moment ?
What does this pair delete do? Looking at a VFr 5th gen
I just realized you have 158 thousand subscribers
Never having owned or ridden a VFR800............what is the purpose of a "Pair" valve for this machine!?!? Anyone know? Anyway..........LOVED watching this video,and showing how You changed the plugs on this and removed that "Pair" valve assembly!!! Thanks for sharing!!!
The PAIR system is a system made to take exhaust gases and put them back into the airbox (or the other way around, I believe it depends on the bike). It's an emissions thing that's pretty stupid to be honest.
The pair system bleeds air from the airbox into the exhaust ports at low rpm's and throttle load..it's purpose is to to bleed "raw" or clean air into the catalyst, the engine runs a little rich while doing so, so the catalyst gets both unburned fuel and oxygen to do its catalysing, and reduces emissions.
Proof that this is the concept comes from when the inlet rubbers get old and start leaking, the bikes exhaust sensors spot a lean exhaust stream and it then closes off the pair system.
Most bikes have the same type of system. I deleted the pair valve on my 2019 klx250 and 2020 r3 as well
@@hellfire08 Got a Bandit 650 from 2011 and was tempted to do the same. But ended up keeping the bike entirely stock
Thanks everyone for your helpful answers!!! Basically sounds like a PCV-system on a cager!?!?! Thanks for taking the time to answer!!! It's appreciated!!! :-)
id strongly suggest finding alternative screws requiring sockets or spanners than those allen head screws for the rear coils. when they dont play ball there a nightmare
What does the pair system do?
Hero, are you a mechanic by trade or are you self taught to do the maintenance and repairs on your bikes?
@herorr is there any harm to engine by removing pair valve system ??
No it’s safe if done properly. It’s for emissions.
Where can I find your center stand? And will it fit on my fz 07
Center stands are standard on the 6th Gen VFR. As far as getting an after Market one. I honestly have no idea
if you dont have a magnet to retrieve spark plug, just put the coil down there it will clip in just like normal then pull it out. no magnet needed
Good tip!
Dropping plugs like that knocks the gap out of spec. Lower gently with magnet or a cut off end from an old spark plug wire, works great. ⚡
I can't believe you dont use a swivel fitting to the plug. Taking a big risk on what you talked about, cross threading.
What is the purpose of the pair?, and why get rid of it?
It’s for emissions. Mine was already disabled so I was just getting rid of it to save some space and weight.
@@HeroRR thank you.
"i used the interior detailer spray" :P
i dont have that, can i use some other type?
If you buy a brass wire brush and use it to clean spark plugs it’s possible to make them last a lot longer. Just check the gap and stick them back in. Simple.
Not sure when this skill was lost. Possibly sometime in the 1990s.
It is more difficult to find brass wire brushes these days, but Lidl was recently selling sets of four wire brushes: 2 steel and 2 brass for a silly cheap price. So I bought two sets.
This works on traditional copper-based plugs but could damage the iridium plugs so might not be a good idea for those type of plugs.
@@NevinPower Who told you that? Was it a spark plug salesman by any chance?
@@NevinPower Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, it is considered the second-densest naturally occurring metal with a density of 22.56 g/cm³ as defined by experimental X-ray crystallography. Wikipedia
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.
Please explain why you believe brass will damage iridium.
I have no idea how humans can regress so much in their comprehension of basic facts in such a short time.
@@G58 cool, do whatever you want. You obviously have not "regressed". I'm sure you're a lovely person having a bad day. Best of luck with your spark plug issue.
@@NevinPower You amused me with your reply:
“G58 cool, do whatever you want. You obviously have not "regressed". I'm sure you're a lovely person having a bad day. Best of luck with your spark plug issue.”
Have you considered that I might actually just be someone using common sense?
But by all means engage in the straw man aspects of the debate and ignore all the facts I gifted you. 🧐😎😜
easy job, go slow and you will have it done in an hour maybe?
also make sure you put antiseze on the threads, some dielectric goop on the coils output and input to help prevent rusting.
if you want grab a bottle of throttle body cleaner and give the tops of your cylinders a good hit, don't flood, but a good hit. let sit for a half an hour / as long as it takes you to do this job and it will help burn off much of the built up carbon.
results, faster ignition / bike turns on faster and more reliable burn/ less low end stumble.
yeah honda says what 50k miles? but you should do it ever 10k miles as a way to also check on the bike to make sure all is well.
Betting eliminating Air system would result in precisely zero gain on dyno. Weight? really now.
It was already blocked off because when you get your bike dyno'd you have to disable it. There are no benefits to having it on so why not get rid of it.
Sorry but all you have to do the pair delete is block the fresh air coming from airbox. Without air going into the pair valve it can not do anything. I would also say only do this mod if you have deleted catalytic converter. The whole purpose of pair is to get rid of unburned fuel in your cat. If you still have a cat all you will be doing is shortening it's life. That's my 2 cents worth.
Yeah it's not a performance improvement at all. It only saves about 2 lbs of weight and does nothing other than that... however it does remove a lot of clutter underneath which I like.
This is great advice, but had to stop watching because you utterly ruined it with that pointless hideous repetitive musac loop. Why do that? It’s truly awful - like being on hold with a government dependent phone line.
Your vids are always brilliant. But This one is the worst vid you’ve ever posted, and I’ve very reluctantly had to give it the thumbs down.
Please, no more nasty musac loops.
Peace
