Hey guys,

I have been working on my 1995CBR900rr for the last couple of weeks to try and get it running. Finally Got it running but now I have a whole new set of issues to deal with. It isn't idling smoothly or dies even at a high idle. The clutch 'clunks' when released when in neutral. The throttle is extremely sticky, and it is slow to rev up and slow to rev down. She is also backfiring.

To get it running I replaced the battery and the oil. I also removed and cleaned the carburetor.

When I initially got her running she seemed to run smoothly, but as I adjusted things (Idle screw and throttle/choke cables) she began running worse, and for shorter durations.

I am not sure of the history of the bike, or even when it was last ridden, as I inherited the bike. I am also new to working on bikes.

Here are a few short videos of it being started and attempting to idle. all less that 45 seconds.


Thanks in advance for any feedback

 

Change your spark plugs, fresh fuel, and new air filter! Do the basics and see if that helps.

 

When you went through the carbs what did you do to them? Exactly what did you clean or replace and what solvents did you use? How old is the gas that's in it and what grade did it start off with and did it contain ethanol (the end of motors as we know them)?

 

Did you check to see if your idle screw backed out completely?
