got a 1982 rm250 have not had many 2 strokes bought this 2 weeks ago for 300 bucks it starts and was riding like new after i did some work to it (not much) the bike accelerates but at a certain point in kinda just revs. Im wondering if to much oil could cause problems like this cause it was fine when i rode it then on the next ride it was having trouble. so i go away for may long weekend change my gear oil spark plug fresh gas and this thing was running excellent. come back from the ride put bike away. go for another ride now the bike is blowing quite a bit of smoke and past a certain rpm it will stop making torque and power to the wheel. it will start driving and then just stop making power. it wont idle i put a liter of Bel Ray gear saver in came back from like a ten minute ride and nothing left in the crank case. i love this bike fell in love with the power and need to fix it lol i only got on ride. ANY HELP APPRECIATED THANKS.
