My 1991 Yamaha FZR600 is having engine dying problem.
the engine starts ok (sometimes). But after that, sometimes the engine revs ok on neutual, sometimes the engine feels like its choking then it dies. Even when Im riding about 30 MPH, sometimes the engine seems to not respond anymore even if I pull the gas lever all the way, then the RPM will slowly drop to ZERO, specially if I pull the clutch, the RPM drops to ZERO instantly.
also sometimes the transmission seems to just NOT let me shift gears no matter what my foot do. I have to shift with my foot like 20-30 times back and forth before I can get in gear, what is wrong?
HELP WOULD BE APPREICATED, THANK YOU

Oh ya and another thing? How do you check to see if the carb is clean or not? If its not clean, how do you clean it?

You really cannot tell if a carb is clean from the outside. Sometimes you cannot tell if it's clean when you crack it open because there are lots of narrow passages that you really cannot see.
Take your carb off, break it apart, remove anything rubber and use some carb cleaner (carb cleaner will destroy rubber). Then blow the carb cleaner out with compressed air, or just wait awhile for it to air dry. Reassemble to factory specs and reinstall on the bike

I dont really know what a carb looks like, do you know where I can found pictures? or a "step-by-step" guide to how to clean the carb?

I would buy a haynes manual if it's available for your bike. It has pictures with a step by step process keyed to your bike.

no offense jack but I think that you are better off taking it to a shop. If you don't know what a carb looks like then it would be hard for anyone, not standing over your shoulder, to tell you how to clean it, take it apart, put it back together and everything that you will be looking at.
On another post someone mentioned looking for cracks in the fuel line and you responded by saying you switched the fuel line from "on" to "res." with no luck. What you actually did was swith the petcock valve and if you have a full gas tank it would make no difference. The fuel lines are the tubes coming off the petcock, which work off a vacuum. If those are cracked then the vacuum isn't working properly and you aren't getting enough gas to the engine.
The best advice so far has been to get the haynes manual for your bike, I second that. We want to be helpful and will continue to do so but it makes it difficult if you don't communicate as much information to us as possible, including your comfort level and skill level for working on motorcycles.
best of luck and happy new year.

why does it that for one minute it works ok, then the next minute it start to act with problems?
I wonder if a oil change will help out this problem? I wonder if it has something to do with the tempurture (bad spelling). or the engine is getting gas at small doses at a time and not getting gas in streams?
I dont know whatever it is?????
