Hi, I am tearing into my 1983 Yamaha XT125 and need to pull the flywheel. I already have a 27 MM flywheel puller for my DT175 and others. It is too large to fit the 83 XT125 flywheel. I have searched everywhere and all I can find are 27MM flywheel pullers listed. Does anybody know the correct size flywheel puller for this bike and if so where I can get one? Thanks in advance. -Tony
