Hey there. I am new to this website and was hoping someone could give me a hand with my situation. I recently obtained a 1993 RM250 from a neighbor that was destroyed beyond belief! I've had the cylinder bored out and sleeved, fresh gaskets on everything, new piston, rings, etc., new reeds, and then some plastic work done. All in all, it's cost me about 450 bucks to get the thing where it is now. I was so excited to get everything put together and pull some sick wheelies, but I've run into problems. The bike DOES NOT want to start without severe coaxing, and usually has to have a run start. When it does run, it blows a lot of blue smoke and bogs out in the top-end. Anywhere in between is great. It has less power than my old Yamaha 125. I've got 150 psi so i know thats not the problem. I've thorughly cleaned the carb. What else? HELP!!!!
