I just had a quick question I was hoping to get some help on. I have a 04 CRF 50 that i cant get running for the life of me. I bought it and it ran fine, but after i had it for a while and put a UNI clamp on it never would idle right. it would just die no matter how high you set the idle. you would think you had it, and then it would just die. I have cleaned the carb and the gas is new. the plug is an NGK and is new. Now i can barly get it to start. when it does it revs up and then just dies. if you try and give it gas, it bogs. i have tried everything. the plug is a sooty black when i pull it out leading me to think it is running to rich, but even with it right, it should idle. please help. any ideas?
