Re: HELP- I\'m Getting Black Smoke!
Well I now realize that i have not given you guys very much information to go on. It is a 93 honda 300 4x4. I live pretty close to sea level (so thats my elevation) I have taken the needle out before to clean it but that was way back and it never caused any probs. I guess you could say that i am a moderatly hard on my bike. I am a mud nut, but i make sure i keep it from getting in the bike. The problem didn't suddely appear, I noticed it getting worse as time went on (over a 6 month period). I know that it is not the air filter.
I got an idea, i will run it by you guys.
In the carb there is a spring loaded valve that limits the ammount of air going through. (not the throttle valve)It is attached / or is part of the vacuum piston. Has anyone seen this become damaged, I know that when a lot of air is rushing through there it is supposed to lift the valve up. I am going to do some experiments tommorrow morning. Any ideas will help!
