So after googling this over and over I checked with a friend who races GNCC/ISDE vet class for years on Suzuki's. He gave me the same answer all the searches gave me. It might be this, it might be that, try this or try that. Before tearing it apart I am going to run ATF in it and change several times to fluch out the gear box. May try 80W gear oil. In our conversation it came up that he has an 05 RM250 he has for sale. Bike was raced for two years, engine rebuilt, and was to be backup bike for 07. Never used again. What's the good and bad on this year? Maybe I just sell the 125 and put him on a 250.
