I recently bought my first bike, and now I'm ready to do my first repairs to it. I'm having two problems. First, whenever I pull in the clutch and start downshifting, the engine dies. Secondly, whenever I get up to full throttle, the bike feels like its pulling you backwards, and sort of misfires. When I start it, it blows blueish smoke and really stinks of gas. So with all these symptoms, I figured it all points to the carb. So I am looking for any help anyone can give me. Any resources, tricks or tips you could give would be great. I haven't done much work on bikes, so I will need alot of help. Thanks.
