idle

It seems that I have this exact issue on my CBR650F 2014: https://650f.bike/threads/rough-idle-on-cold-start.2879/ Once warmed up the issue seems to go away. It seems from the Youtube/forum comments that the issue is the IACV. I found in service manual how to replace this...

Hallo. I have a problem with my CB650f (2015 abs) which seems I just cannot solve. At the end of the season I noticed a couple of things, of which I do not know if they are connected 1. After a drive with some fast acceleration i noticed a rotten egg smell coming from the bike / exhaust. This...

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...

Just a quick question. I've recently unrestricted my CB650R, and after doing so myself, I noticed the bike idling extremely high. Cold starts are at 2.8k, and even when warmed up, it idles at 1.7k. The shop that did my tune mentioned no major issues with the bike, other than the high idle, and...

Hello all, This is my first time posting here so apologies if I mess something up in the post. The bike is a 2016 CBR650F with ~23,000 miles with an akrapovic exhaust, besides that I believe it is stock. I got the bike this spring and went about 500 miles before having any issues. My issue is...

Hi, I've got an annoying problem with my bike and wondering if anyone has got any good ideas to try? The bike is a 2015 UK CBR 650 and the problem just started out of the blue a few weeks ago. It's started with a intermittent high idle, where the bike would tick over at about 3000rpm. It...

Hello, I have a CB650F (2014). My nightmare began when I couldn't start it for a while during a winter (Battery, sleeping outside,...) It finally started and i could drive it again. But then i let my bike sleep for almost a year. (in a garage). It started right away but a probleme appeared: The...

Hi everyone, Here is the problem, I've got an issue with my cb650f (2014, hrc one) When starting in cold conditions (whenever the temp outside) my bike start then there is no starter (starting from 1200rpm) and the idle go down (1000rmp then 800...) then she stalls I've got a video from...

After going through as many videos I could find on here, nothing seemed to be the same as what I'm experiencing, and as far as I can tell, it's not the pair valve system. The right side my engine has just started rattling after a long ride. It doesn't seem to change with rpm's or speed and can...

Hello everyone, I bought a 2018 CB650F yesterday, I wanted to know what is the correct engine RPM in idle mode? Mine is about 1250, is this normal? I feel like the engine is running fast! Thank You.

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...

Hello. I've got myself in a bit of a pickle guys. Over winter I've been changing the handlebars on Sweethearts CB650F. I now have issues I can't work out. Changing the bars has involved lengthening the front brake hose and the clutch cable. Every thing else is fine. Brakes bled up fine, and...

Don’t know if you can hear it in the video, but it almost sounds like a miss? Goes away when I give it any amount of gas. Does it cold or hot. Any ideas?

Hello everybody, I have a weird issue to report and would like a suggestion what I could do about it. When starting my bike cold (not driven yet) but in warm conditions (today were about 28°C) it revs up once to about 8k and then goes into idle with around 4k. I have to ride for about a...

Hello everybody! I have an issue with my CB650F (2016). It very often gets rough idle when cold. Exactly the same bahaviour: Has anyone encountered such problems?

Full story, picked up a 2014 CBR650F, and after a few days I had a weird issue where if the RPM's went over 3k, on the way back down it would hang there unless I fed the bike clutch to force it down a little and then it would drop to a normal idle. Lifted the fuel tank and looked around, found...

General question to all other owners of the 650R, how long does it take for the idle speed to drop from the initial 2000rpm at cold start-up to normal idle of just over 1000rpm? My bike seems to take about 3 minutes. This is first brand new bike I have had and my previous bikes and my current...

Hi, i was changing hand bars on my bike and one of my throttle cables fall off from other side(on fuel injectors) . I needed to remove fuel tank,air filter to put it back on. I reasamble everything double check all cables going to air filter. I turned the bike on idle was too high. Before was 2k...

Hello! I have encountered a slight problem regarding my 2017 CBR650F. During the winter, me and my dad who is a licensed motorcycle mechanic have tinkered with it. The bike has been restricted to 48hp to be legal to drive with an A2-license, an Akrapovic exhaust, a K&N air filter and some other...
