Having bought two TM 125 MX, one is a complete basket case that had been left out side to the elements, with the crankcase,s semi split. given up because they couldn't get them apart, I got them apart but not in the correct sequence. The crank needed rebuilding with conrod kit but the shift/selector drum was stuck in the crankcase because of two screw's that would not shift on the holding plate, so marked up on case and drum how it sat for reference on rebuild, took case to local MX shop who sorted it out. Having got the part's home to rebuild engine all my marks are gone, numpty me did not take picture's and can't work out how the drum is meant to be when in neutral with selector forks & gears when installed in case. IE: which groove's the forks sit when in neutral. Search web and workshop manuals but can't find anything. Any help would be appreciated. Ignor blue pen on shift drum. As you can see three selector forks and four possible locations. Rebuilt loads of these engines in the past normally have reference to rebuild, probably be obvious when some one like this. Thanks for any help.
