spark plugs

Guys, maybe a dum one but - do I have to remove the spark plug cap/nut before installing on my CBR650F 2016 ABS? I am talking about the little screw on caps/nuts: Appreciate it in advance! :)

Hello, I am a new owner of a Honda CB650R, the motorcycle was bought with a defective cylinder head gasket, it was repaired but I have a question. In the repair manual I saw that one ignition coil is for spark plugs 1 and 4 and the other for 2 and 3. On mine I noticed that one ignition coil is...

Been having some strange issues with my cbr650f. Only had it about a month and it has about 8000km on it. Previous owner also rarely rode and it pretty much just sat in his garage for like a year. Engine is taking ages to rev back down to idle and is getting stuck on 3000rpm then takes several...

Recently had my spark plugs replaced by my mechanic from stock to its iridium equivalent (NGK CR9EHIX-9). Throttle response feels significantly improved but I can tell while idling, even after fully warmed up, that the engine noise now has these small, irregular hick-ups, almost like it skips a...

Hi guys, i just changed my plugs today and noticed that the old ones look kinda brownish. Plugs were a little bit wet with a drop of gasoline. But nothing much. I’m not much of an expert, but is my bike running good or too rich/ lean. The bike is from ‘21 and currently at 12.900km

Hello, I recently changed the spark plugs and air filter in my cbr650f. It was a bit tougher than expected but not too bad. Upon finishing, the bike started kinda rough and had the engine light flashing, I took it apart and found a missing connector near the spark plugs. I reconnected that and...

Let me know whatcha think? It felt like dark honey. Can it be copper grease? Tips were totally dry. Same on all of the spark plugs. Ps: Changed to Iridium tips. Goodbye spark plug maintenance:)

Hi folks, Am new rider and really could use some help! Am facing a sudden problem that my CBR650F 2018 ABS it’s only 9K miles . Started to lose power at high RPMs from 5K and above and the acceleration is not consistent, feels like cutting as I go up after the second gear, or like the gas is...

When replacing the spark plugs, check the owner’s manual or service manual first to determine the correct spark plugs for your bike. Unless you have a heavily modified bike and you know what you are doing, you should not deviate from the manufacturer’s specifications. Honda recommends either NGK...

I ride a CB650f from 2017 which has 15 000km. I have an IXIL aftermarket exhaust (without the db killer) and without an ECU flash/remapping. I made around 6000km in last year (since I bought the bike). I started noticing some problems as time progressed... *Exhaust pipe started to fill with...

Service Interval I am at ~15,100 miles and I missed the replacement interval for the air cleaner and I am coming up on the spark plug replacement interval so I decided I should probably just change them both right now (since I am doing other maintained/mod installs right now as well). I have...

I stumbled across this thread about removing the PAIR system and decided it sounded like it would address some minor issues for not a lot of money, and since this job would require removing the tank I figured I may as well swap the stock plugs out for a nice NGK iridium "the last plugs you'll...

Hi Guys, Could any body update about Brisk ZS performance spark plugs have anyone used/using the same here. Want to know what are the postive and Negative of the same

Want a cheap power boost (recovery) and a smoother revving engine? You may want to consider side-gapping your spark plugs. I did this on my Grom with an NGK iridium plug and it really smoothed out the powerband, and now my CB. It is very easy to do: Tools: - Hacksaw or Dremel with cutoff...

it was a scheduled service interval recently. not sure what was to be done but I got out of sequence and did Oil, oil filter, Air filter and sparkplugs. I have done an air filter change 24,000km ago and at the time, I hap propped up the tank to avoid disconnecting the fuel line. mostly because...
