I have done a search on this and found a lot of usefull information, but none that pertains exactly to me. I have a '91 xr600r, I run the twin air filter cage and filter, and most of the time I have the baffles out of the stock exhaust. The bike has a bog when you hit the throttle hard, I understand that this is natual for a stock carb, but I would like to minimize it as much as possible. I have never rejetted a carb before, but I'm going to give it a try. I was hoping that you guys could give me some advice on what settings to try and perhaps point me to some literature that could teach me what they all mean. thanks!
