Hey guys,i need some fork oil help.I have a 1990 YZ 125 that i'm working on and need some info about the fork oil weight. It has the amount, but not the weight? I always use 5 wt in my KTM, but am having a hard time finding any info on this older gem. Any input would be welcome, and thanks for the help

Check Racetech out. They will have your fluid levels and spring recommendations if you need stiffer springs. You should probably find an an online service manual. With a old bike like that, the manual makes life a lot easier.

Thanks, I'll have to call today and see what they recommend.

Might also consider checking the Yam Wrench Report for that year also.
