pair

I’ve finally had chance to look inside the gubbins of my 2018 CB650F. It’s done 7k, it had 3.5k when I bought her a year ago so I had no reason to as it runs perfect. It’s standard except for a full stainless Lextek exhaust system which was on when purchased. Note: the Lextek was designed to...

Installed CS Racing exhaust yesterday, and thought was a exhaust leak on the bike, messed with it and messed with it and im unsure if its a exhaust leak or a pair valve making noise. It seems to disappear or be every quiet around 3k. Potentially need to replace exhaust gaskets but bike is only a...

Hi, Is this the right hose to block with a marble? I've read the "PAIR VALVE REMOVAL - CHEAPEST AND EASIEST WAY" thread and it was different from it. If the picture I provided is the right one to be blocked - is there any hose do I still need to block or just this one?

Quick question, apologies if there’s an existing thread. As I’ve been researching PAIR valve deletes, it seems that the only prerequisite mod is a cat delete. The Akrapovic S-H6R11-AFT does not come with a cat installed. Am I correct in assuming that I can install the PAIR valve delete...

Hi all, wondering if anyone can give me any insight into this. I recently did a service on my 2018 CBR650F (plugs, air filter, oil change). When I was removing the air box to access the plugs I noticed that one of the hoses at the front of the air box (the one on the right side if you're sitting...

Evening all, I have a 2015 CBR650F and I have recently noticed a rattle coming from what I think is the top of the engine. The bike didn't have this issue before I fit a full SP engineering exhaust system which leads me toward the rattle being from the PAIR valves so I am going to blank them. I...

Hey Im considering getting the ECU flashed to a custom map. I will keep the stock exhaust as noise regulations are getting pretty strict here(dont wanna waste money on aftermarket exhaust if i cannot ride it legally around here) So my question is, should i remove/block off the pair valve system...

Hi, I've seen this video for cb650R For Cbr650F (ebay picture) what hose would I block?

Hi All, I know there has been lots of discussions about Pair Valve issues, removal and noise. I rode my bike today after a few months off. The bike rides fine but when ticking over there are noises which make it sound like marbles, clicking and clacking sounds. I thought it might be cam...

Hey so recently I had my bike flashed tuned to de restrict it and tuned for my exhaust and air filter. Next I’m going to block off the pair valves because the noise it makes is quite annoying. Will I need to get a re tune for this or would I be fine blocking them off and riding?

So Ive watched a few videos about plugging the pair valve hose but when I got into it, the hose is not there where it was in the video. 2016 Cbr650f. In the video it shows the hose coming down over the top of the airbox cover right under the tank? Attached a pic of mine…

I’m in the middle of blanking my pair valves on my 2019 CB650R Tanks off, filter housing off etc. I can now see where the valves are located, further forward than I had thought. I realise there is a thread by Aaron for this, but I can get no write up showing, just around ten pictures, which...

Hi all, After some research with some motorbyke workshop, I discovered that the noise (ticking) is from the pair valve system. Introduction: I bought the bike with 5k miles and MIVV exhaust. The bike had a Power Commander installed, but the old owner sold it before, so I've bought the bike...

Hi, I've been reading the thread about removing pair valve but just wanted to get some clarification. Is it safe to do so with stock exhaust. Some users mentioned cat being destroyed, but apart from that would blocking the pair cause damage to engine or anything that may affect the performance...

...if the previous owner has already removed it without taking the bike apart. So I've been searching the threads to try to identify if I need to do the mod. Basically my throttle seems very sharp across the rev range but especially at low revs. Some people say removal makes the throttle...

Hi Everyone, I was wondering if someone with a CB650FA 2017 could post a video clip of the engine idling after a ride, so it’s hot. But recorded around the right hand side near the cam chain tensioner and cam cover. I know about pair valve noise, but think the cam chain maybe a bit noisy...

Hey all, Remote assistance really appreciated if anyone can help. Brought my bike 2 months ago, second hand and been riding it with no issues. Put on a couple of hundred miles as it’s only just starting to be nicer weather here in the U.K. Bike sounds great and no issues noted, test rode fine...

Hi all, First post on here so hi everyone. Recently purchased a mint 2015 650F with 5k miles. It has a full Honda service history so thumbs up. A little history on the bike, it was not used much in the last 2 years by the previous owner, it did 4 miles in the last year and less than 1000 the...

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...

-Did some measuring and made a quick sketch this eve. Now that I'm back at work, i'll mill up a couple of these plates. -and maybe make a better drawing for you all?
