I have a 03' YZ450. The guy before me(1st owner) only used Yamalube 4R 10W-50R semi-synthetic racing oil. I bought a case of Yamalube 4 20W-40 from Rockymountainmc.com because they had a reasonable price.
Would I be doing this bike a disservice by doing so?Any performance problems?
I really would like to hear from my Yamaha colleagues to know what you think...:bonk::thumbsup::thumbsup:

No issue...I'm getting ready to do the same thing, but I'm going the other way and switching to synthetic oil.

Change the oil frequently; 5-6 hours max. Yamalube does not retain its high temperature viscosity particularly well according to testing I have seen.
