I just got a 1998 rm 125 and bought some belray gearsaver transmission oil, and that stuff seems to work really bad as for it creates false nutreals in 5th gear and takes like 2 clicks to shift into 5th gear, i noticed alot of people use type f oil and i just dont want to use it because it isnt full protection, i am looking for a 10-40w 2 stroke oil, does anyone have any suggestion on what oil to use, im not to concered about the price, i just want for my bike to shift into gear smoothly and no false nuetrals!!!!
