[MatanCb650]

Hi there i just bought this cb650f 2016 abs model. And when I ride it at the beginning it feels ok and after few minutes it’s not having power and it sounds wired like just 2 cylinders are working..
Somebody can help me fix it please 🙏🏽

You’re not giving us much to go on. If it feels like it’s running on 2 cylinders, I’d suggest verifying it by the tried and true method of squirting water on the pipes to see if one or two are colder than the other and know that this bike (for some crazy reason) still uses coils for ignition and there one per two cylinders. So if you are losing spark to 2 cylinders, it’s likely ignition related.

We’ve also seen coils fail on this forum so that wouldn’t be uncommon.

From there we would need way more info. Did it ever run right, just start one day, miles on the bike, service history, mods you’ve done, etc.? There is a link to the service manual in the resources section to help troubleshoot.
