Hi Ruban welcome to the forum, sorry you're having issues with your 14, the guys will be along shortly & may be able to assist you.
I think a bit more detail / history on the bike & the issue would help in diagnosis. Good luck.
Welcome to the forum Ruban. :onya: Does it start up easily and run fine until warm them stall and not tick over smoothly when you restart it?
Welcome mate,
A blocked low and high pressure fuel filter can also contribute to rough running, same as incorrectly balanced throttle bodies, tp and stp sensors, perished vacuum lines and dirty injectors.
Also check the air filter and replace if dirty and check spark plugs.
Usually an introductory message at the right spot will help you get further responses, and perhaps some more detail about your bike and the issues you're having.
Doesn't a faulty clutch switch result in rough/poor running??
Only time I had black smoke was a blocked high pressure filter.
My assumption is the lower fuel pressure it caused resulted in a very poor spray pattern from the injectors and poor, incomplete combustion.
Yup, you need proper pressure behind the injector for a good spray pattern, a blocked hp filter limits the rail pressure too much.
