I have a 2 stroke Yamaha RXZ135, 135cc 2 stroke, reed valve with boost bottle aircooled engine.
I've been using Yamalube 2-S on it, it has about 3700 miles. Last two times I cleaned the sparkplug, the color was fine, but there were ash deposits on it!
Also the bike smokes quite a bit when cold.
Only way the ash could have got there is on the oil, so I guess it has a high ash content, but from the few information I was able to gather on the net (look for Yamalube 2-S and you'll find links to every yamaha product, except for actual info on the oil), it seems that it is no good.
How bad is it? Should I use all the remaining bottles I have of it and start using a different oil?
No Amsoil nor blue marble is available in here, I'm limited to a few types of Maxima and Motul, plus the cheap Castrol 2 stroke oil and even less known brands that will never touch my bike.
