Anyone else have problems adjusting the chain tension on there DRZ? I have a DRZ400S with Excel rims (supermoto setup) and I have had a lot of problems getting the chain adjusted. It seems like the axle continues to slip thus my chain tension gets REAL lose. On my sportbike I had a bolt that youused to adject the tension, on the DRZ they have a built in tension controller that does not seems to work very well. Am I missing something? Is there a trick to getting this to stay? I am using 42 lbs/torque per the DRZ manual. Any help would be greatly appreciated !
