I'm almost due for my first oil change. The previous owner said he changed out everything when he first got it... And i'm about 1k miles from being due (engine oil). He said he was going to put syn 3 20/50w in the tranny, which is what is in the primary... He said he had "rev tech" in the tranny now. When i go to do my oil change I kinda wanted fresh oil all the way around (even though the bike only has 13k miles on it) Anyway, i just wanted some feedback from a more knowledgable source, this is my first EVO. Is putting syn 3 in the entire thing a mistake? Should I use a different weight in the tranny? I should add i'm a big fan of synthetic oils in my bikes, and i think its wise to spend a little extra on oil. I have a bone stock 80 ci EVO motor and a 5 speed tranny.
