elloo..
My cbr400rr nc29 is runnin on only 2 cylinders that is left cylinders and right cylinders are not working properly...
When i use wet cloth on left exhaust pipes they are very hot n in the same way when i use to both right exhuasts they both are semi hot...
Even i tried using hands on air intake on carbs, left both sucking air strongly n right both none:( ..
Since i am thinking about compression in piston is not good...so how to regain it back...
Change piston rings or piston?
And more over my plugs getting dry fouling even though i bought new air filter n plugs...

:(
Please tell me

Did it run correctly before this?
It could be the carbs need cleaning and setting up.
You could also have a bad head gasket between those two cylinders or the valves need setting.
Can you do a compression test?
